Isabgol belongs to the family Plantaginaceae and genus Plantago with chromosome number 2n=8)). The seed husk of this plant is commonly called Psyllium . The seed husk has the property of absorbing and retaining water which accounts for its utility in checking constipation, diarrhea and intestinal irritation. It is diuretic, alleviates kidney and bladder complaints, gonorrhea, arthritis and hemorrhoids .There is an ample scope to increase the productivity of isabgol through genetic improvement. The genetic improvement is primarily depends upon the nature and magnitude of variability in plant characters, overall genetic diversity among genotypes and association between characters. The limited existing genetic variability is major bottleneck for the improvement of the isabgol .Mutation breeding is ultimate source of variation. It provides raw material upon which other factor of evaluation act and therefore all the new species ultimately arises from the mutation.

Grain production is a complex phenomenon, entailing several contributing factors. These factors influence grain production both directly and indirectly and the breeder is naturally interested in investigating the extent and type of association of such traits. Towards a clear understanding of the type of association, correlation, path and divergence analysis are logical steps. Studies like heritability estimates could also be helpful to know the performance of parents in hybrids. Similarly, Knowledge on the extent and the pattern of genetic variability present in a population is essential for further improvement of any crop. At present, there is lack of detailed information pertaining to these aspects. Therefore, this book intends to show comprehensive logical steps that a plant scientist should follow to reach a concrete conclusion on the variability and genetic relation of different characters taking an experiment conducted in bread wheat as an example. The book is important for plant breeders and other plant scientists interested in learning more about the ways of crop improvement.

Tomato (Solanum lycopersicon Mill.) is an important vegetable crop belongs to family solanaceae. It is well known and very popular vegetable among farmers and grown successfully throughout the world. It is used as vegetable and ripe fruits are also utilized into salad, soups, pickles, sauce, ketchups etc. Yield of tomato crop is primarily governed by the genetic makeup of the variety. Thus, full genetic potential of the variety can be utilized through recommended cultural practices. To develop the variety, existence of significant heritable variability is of prime importance. Some biometric techniques like variability, correlation and path analysis provide information about the relative contribution of various yield related traits. Genetic and phenotypic correlation coefficients seek out the association between yield and yield contributing traits in tomato. Thus, these biometric techniques help in selection of superior plant genotypes for breeding programme.

Grain amaranth (Amaranthus hypochondriacus L.) production has declined mainly due to lack of producer awareness of its nutritive value, non-availability of suitable high yielding varieties and lack of improved production techniques. Varietal improvement is needed to increase yield potential of this crop. Proper plant densities is essential in maximizing grain yield. In this context, there is an imperative need for the breeders to evaluate and identify the stable genotypes that could give standard performance when tested under different plant density levels. Population density is a major environmental factor influencing the genetic parameters like variability, heritability and genetic advance among the characters. Study of the extent of such influence of different plant density levels in these genetic parameters is required to formulate appropriate breeding strategies.

Soybean is one of the most popular protein rich leguminous crop used as food and feed. However, yield performance is very low and varied in different environments drastically in Bangladesh. Therefore, the present work has been planned to select high yielded stable soybean genotypes through mutation breeding. I performed two experiments where fifteen soybean genotypes were used. In the first experiment the superior soybean mutant genotypes were selected by testing yield performance and genotype-environment interaction was observed for stability. In the second experiment selected soybean mutants were characterized using RAPD marker. Polymorphic bands of RAPD markers suggesting that genotypes were different from each other and possessed genetic diversity among them. Thus, these markers could be efficient for comparing the genetic relationships, patterns of variation and measurement of genetic distance among the selected soybean genotypes. Therefore, from these soybean mutants SBM-09, SBM-17 and BINA Soybean-1 had been selected as stable and higher yield performing genotypes for enhancing yield.

Genetic variability is prerequisite feature for crop improvement programmes. Plant breeders are handicapped due to lack of availability or non-existence of adequate genetic variability. The induced mutagenesis is one of the promising approaches for creation of new genetic variability and offers the possibility of inducing desired attributes that either cannot be found in nature or have been lost during evolution. Recent reviews on mutation breeding indicates that although induced mutagenesis is a best approach for creation of genetic variability but most of interest paid towards crop plants, even widely used medicinal plant spp like C. roseus , an anticancerous and antihypertensive alkaloid yielding plant could receive little attention where its application is helpful in developing improved ‘idiochemovars’. These ‘idiochemovars’ are important for industrial crops, such as medicinal plants, content of the economically important metabolites is more important than the yield of the plant parts containing the metabolites because it determines the cost of extraction of the metabolite.

Chickpea is an important legume grown in more than 45 countries globally. More than 95% of the area, production and consumption are in the developing countries. Due to its ability to grow under stress environments, its yield provides the much needed food, which enhances food security. The protein content in chickpea exceeds 20% which makes it an important source of protein for the rural poor who can’t afford expensive sources of protein. It has also been found to be an excellent rotation crop because it fixes nitrogen and its ability to grow under residual moisture. However, with the increasing temperatures, its yield will decrease in the semi arid tropics. It is therefore important to breed for varieties that can grow under elevated temperatures. For this to be possible, genetic variability has to be determined and more importantly sources of high temperature tolerance identified. This book looks at genetic variability of over 100 chickpea genotypes and identifies sources of high temperature tolerance. It also looks at heritability of selected traits in chickpea.

Phylogenetic relationship among local and exotic genotypes of Capsicum were elaborated through morphological characterization and molecular markers.Protocols for isolation of total genomic DNA and seed storage proteins were optimized for Capsicum genotypes. Four RAPD primers were used to amplify genomic DNA. Unweighted Pair Group of Arithmetic Means (UPGMA) estimates of Genetic distances (GD) using RAPD primers ranged from 0 to 100%. Total seed storage proteins profile of the genotypes using SDS-PAGE analysis showed high range of genetic distances i.e. from 0–100% among various comparisons.The data obtained from PCR and SDS-PAGE was also used to study phylogenetic relationship through constructing two independent dendrograms. Dendrogram based on DNA data showed that the twenty-five genotypes were clustered into four groups.No such grouping was visible in the dendrogram based on the SDS-PAGE. Hence it was concluded that DNA based data is more useful for phylogenetic elaboration of Capsicum genotypes. Further morphogenetic and taxonomic study is recommended for assessment of the exact taxonomic status of genotypes segregated into different groups.

Tea plant, Camellia sinensis (L.) O. Kuntze, used to produce the oldest and most popular non-alcoholic soft beverage across the world, is one of the most important cash crops of many countries, including Vietnam. Known as a freely cross-pollinated plant, with many overlapping morphological, biochemical and physiological attributes, tea can not be separated into discrete groups to identify various taxa. Since hybrids are used and clonal propagation is recommended, genetic diversity of tea can be diminished if care is not taken. Information on taxonomic characteristics, genetic diversity and biogeography of tea in the living collections may help in identifying genotypes with high productive potentials which could be used as progenitors to improve the existing genetic base of commercially grown tea. Revealing the genetic diversity by using molecular markers has assisted breeders assigning appropriate parents to be used in crosses.

Turmeric (Curcuma longa L.) is one the best known among various taxa of economic, medicinal (anti-cancerous, healing, blood purifier properties), ornamental and cultural importance of the genus Curcuma. India and Thailand with at least 40 species in each area have the highest diversity. Genetic variability in a population can be partitioned into heritable and non-heritable variation with the aid of genetic parameters such as variance, genotypic coefficient of variation, heritability and genetic advance, which serve as a basis for selection of some outstanding genotypes from existing ones. Cluster analysis have proved to be effective methods in grouping turmeric accessions that may facilitate effective utilization of the accession in crop improvement programmes through selection, as conventional breeding is difficult in this crop. Moreover, correlation and path analysis of morphological traits indicated importance of desirable traits for strengthening the turmeric breeding programme for higher rhizome yield.

The hilsa shad, Tenualosa ilisha is an important anadromous clupeid species from the Western division of the Indo-Pacific region. It constitutes the largest single fishable species in Bangladesh. Information on genetic variability and population structure is very important for both management and conservation purposes. We examined genetic variability and divergence in two riverine (the Jamuna and the Meghna), two estuarine (Kuakata and Sundarbans) and one marine (Cox’s Bazar) populations of T. ilisha by applying PCR-RFLP analysis of the mtDNA D-loop region. The amplified PCR products were restricted with four restriction enzymes namely, XbaI, EcoRI, EcoRV, and HaeIII. High levels of haplotype and gene diversity within and significant differentiations among, populations of T. ilisha were observed in this study. The UPGMA dendrogram based on genetic distance resulted in two major clusters, although, these were subsequently divided into three, corresponding to the riverine, estuarine and marine populations. The study underlines the usefulness of RFLP of mtDNA D-loop region as molecular markers, and detected at least two differentiated populations of T. ilisha in Bangladesh waters.

BREEDING INVESTIGATIONS OF BIPARENTAL MATING IN BHENDI (Abelmoschus esculentus (L.) Moench) The genetic improvement of any crop relies mainly on the presence of substantial magnitude of variability in the populations and the extent to which the desirable trait is heritable. Breeder’s very often use segregating populations as source populations to exercise selection for identifying homozygous recombinant lines with better performance to develop varieties. Most often the source F2 population of single cross hybrids and/or double cross hybrids would offer limited opportunities for achieving high success because of narrow genetic base and impose restrictions on the chances of better recombination and also associated with the weakness of causing rapid homozygosis and low genetic variability. However, biparental mating, on the other hand is expected to break larger linkage blocks and provide more chances for recombination to occur. It is a useful system of mating for generation of increased variability and may be applied where desired variation for traits of interest is lacking or insufficient.

Tomato [(Solanum lycopersicum Mill.) Wetted] is one of the most important vegetable crops grown in India. However, modern cultivars of tomato have a limited genetic diversity further the demand for high yielding disease resistant hybrids is alarming. In this study an effort was made to increase genetic variability for development of ToLCV resistant high yielding varieties and hybrids by utilizing exotic tomato breeding lines. Diversity analysis of 19 exotic tomato breeding lines and popular varieties viz., Pusa Ruby (P20), Vaibhav (P21) and Arka-Vikas (P22) was made with the D2 analysis, PCA, RAPD and SRAP markers, which revealed that exotic lines are diverse from popular varieties. Nineteen exotic tomato breeding lines and cultivars viz., P20, P21 and P22 were crossed in line x tester design to assess the combining ability and heterosis. A perusal of the results indicated that P21 x PT4227A, P22 x CLN2123E, P21 x CLN2768A, P21 x CLN2777F, P21 x CLN2400B, P22 x CLN2460E, P22 x CLN2777B, P20 x CLN2498E and P20 x CLN2777F showed significant heterosis over the best check hybrid. Further these hybrids could be used to develop mapping population and breeding for hybrid development.

Substance (e.g., heroin) dependence has been influenced by both genetic and environmental risk factors. It has been estimated that genetic factors contribute to 40%–60% of the vulnerability to drug addiction, and environmental factors provide the remainder. The aim of the work in this book is to identify genetic markers within selected candidate genes that may influence substance dependence susceptibility and treatment responses. Pharmacogenetic studies can assess the effects of genetic variation on the risk for a particular phenotype (e.g., being an alcoholic). In addition, pharmacogenetic variability in treatment efficacy and adverse reactions can be investigated to identify particular genetic variants associated with altered responses. Knowing the genetic factors that are involved in substance dependence and treatment will allow us to more accurately match individuals to different treatment options. Our improved understanding of the role of genetics in drug metabolism may also provide additional information about an individuals’ metabolic pattern or drug consumption patterns. The information may also enable forensic toxicologists better interpret post-mortem toxicology results.

The field experiments were carried out in the Institute of forage crops - Pleven during the period of 2009 - 2012. Studied was the variation of some genotypes of forage peas belonging to different subspecies with the directions of using methods of pick out, sexual hybridization and mutagenesis. Applied was crossing between varieties with alternative traits. It was found that in F2 generation there was great diversity of types and created opportunity for selection of suitable progenies. Perspective lines steady on stress factors were selected. The inheritance of the element of productivity is determined mainly by additive dominant gene effects. The phenotypic diversity of the quantitative traits in F2 is characterized with continual variability and transgression activities. The uses of method on experimental mutagenesis is analyzed the reaction of four forage peas genotypes to radiation influence (gamma rays Cs137). For actively influence on the mutability and the heritability of the organisms should be matched with suitable methods and ways for change of the ancestral information.

Data about rare genetic disorders in Iraqi patients is not available. Iraq is a country that has been in turmoil due to the devastating impact of three major wars and a long period of imposed economic sanctions over three decades. The development of genetic research in this country has been markedly hampered. Relatively common genetic disorders in Iraq include Down's syndrome, hemoglobinopathies (B-thalassemias, and sickle cell anemia), glucose 6 phosphate dehydrogenase (G6 PD) deficiency, Duchenne muscular dystrophy, and achondroplasia. In an experience extending over about 20 years we have documented the rarest genetics in Iraqi patients. Some of these disorders are very rare through out the world such as Coffin Siris syndrome and cutis laxa type II (Debre type) some of these disorders is very rare in Arab population such as Nephropathic cystinosis and Aicardi syndrome. A new clinical association of a genetic nature has been observed for the first time in Iraqi patients. A very rare combination of two genetic disorders was also observed.

‘‘If it were not for the great variability among individuals medicine might as well be a science and not an art.’’- William Osler. Although periodontitis does not follow Mendelian inheritance patterns, evidence is mounting of important hereditary influences. A number of aspects of the inflammatory and immune responses, that are suspected to play a role in the development of periodontal disease, have a clearly defined genetic basis. Possible associations between several of these aspects of immune defence and genotype have been discussed in the context of both family and population studies.

Tomato (Lycopersicon esculentum Mill.) is an important vegetable crop grown through out the world under outdoor and indoor conditions. The crop is subjected to attack by various diseases and early blight caused by Alternaria solani (Ellis and Martin) Sorauer is most destructive one. Field screening of 81 tomato genotypes against early blight indicated that 11 genotypes were highly resistant, 23 resistant, 22 moderately resistant, 15 susceptible and 10 highly susceptible. Genotypes resistant to early blight gave much higher yield as compared to susceptible ones. All the test fungicides (Dithene M-45, Blitox-50 and Kavach) and neem pesticides (Bioneem, Fortune and Nimbicidine) exerted possitive effect on disease control and yield increase of the test host plants. Highly resistant wild species, L. pimpinellifolium and L. peruvianum had higher quantitiy of sugars, phenols, vitamin 'C, total free amino acids, total crude protein, chlorophyll and NPK content in comparison to susceptible genotypes at pre-infectional stage, whereas, after-infection a marked reduction in the level of these constituents was observed in susceptible genotypes than in resistant genotypes.

Sesame (Sesamum indicum L.) is the oldest oilseed crop known and cultivated by man. Among the oilseed crops, sesame ranks first for having the highest oil content of 46-64 per cent and 6355 K cal per kg dietary energy in seeds. The seed of sesame is also rich in protein (20-28 %), sugar (14-16 %) and minerals (5-7 %).The specific reasons identified for the low yield of sesame in India is due to its cultivation under sub-marginal lands without due importance to the choice of appropriate season, high yielding variety, nutrient management and new agro-technological packages. One way of increasing the productivity in sesame is by increasing the number of branches leading to increase in total number of capsules per plant. Maintaining the plant population also plays a vital role in realizing the yield potential of sesame. Possibility of cultivation of sesame in summer season under irrigated condition wherever supplemental water resource is available had not been tried or practiced by the farmers of this region. Therefore, selection of suitable variety, time of sowing, appropriate geometry and agronomic technologies are importance for increasing the productivity of sesame in this region.

Complementing breeding effort by deploying alternative methods of identifying higher yielding genotypes in a plant breeding program is important for obtaining greater genetic gains. Spectral reflectance indices (SRI) are one of the several indirect selection tools that have been reported to be associated with many physiological processes of different crop species. The value of SRI as a plant breeding tool for yield improvement has not been well established. Therefore, this book provides a comprehensive analysis of the potential use of SRI as a plant breeding tool for yield improvement using breeding populations and released cultivars of wheat. Association between grain yield and SRI, biomass and SRI, heritability of the SRI and yield, response to selection and correlated response, relative selection efficiency of the SRI, and efficiency in selecting the higher yielding genotypes by the SRI are discussed. The findings should help wheat breeders to utilize SRI as an indirect selection tool for yield improvement.

African Marigold (Tagetes erecta L)is an important commercial flower of India, belonging to family Asteraceae. It is also known as friendship flower in the United States and represents vulgar minds. Easy cultivation and wider adaptability of the crop has increased its popularity . Flowers are sold in the market as loose flower or for making garlands, offering in temples, churches, festivals, beautification and landscape. Although marigold is a very important flower, yet very little research work had been done towards the crop improvement. It has a lot of variation with respect to growth and flower characters, which varies with germplasm. Germplasm serves as valuable natural reservoir in providing needed attributes for developing successful varieties. However, the extent of improvement depends upon the amount of variability in different characters present in the crops, which is an indispensable prerequisite for successful breeding programmes. Therefore, selection accordance to high GCV and PCV is more effective for a particular traits. High heritability alongwith high genetic advance in per cent of mean provides a best guiding to formulate effective selection programme.

Need for the improvement in wheat yield is increasing continuously due to day by day increase in human population on the same land. This challenge is much greater in the developing countries than the developed world. Many breeding programs are based on selection of desirable parents for hybridization that’s the main source to create genetic variation which is heritable to offspring. This study was carried out to have information on the magnitude of heritability and genetic advance of various important wheat parameters as it plays an important role for planning breeding strategy. For this purpose second filial (F2) generation of ten cross combinations involving seven wheat varieties/genotypes were studied. These were planted in field in a Randomized Complete Block Design with three replications. At maturity 200 plants from each cross and 20 plants from each parent were taken and data were recorded. The information derived will be very helpful to make improvement in wheat yield through reliable selection as it is suggested that varieties/genotypes showing good results should be given due importance in future breeding programs.

Following its importance in the export market, the production of sesame in Ethiopia is booming in the last decades. Humera is the major sesame producing area in Ethiopia. This area is also known for its production of premium quality sesame‘white sesame'.However,productivity (kg/ha)of the crop remains very low. There is a wide gap between the yield obtained at research station (2200 kg/ha) and under farmers traditional management practices (450 kg/ha). Among others,water-logging and higher seed rate are the most important factors that limits sesame yield. Therefore, this research was conducted to estimate the effect of planting methods and spacing on the yield and yield components of sesame. The result indicated that sesame yield was increased by 150% when planted on ridge,compare to flat planting. Moreover,ridge planting associated with 20 cm between plants and 40 cm between rows has increased yield ha-1 of the crop. This would give an important insight to increase sesame yield in the study area in particular and in similar area of the world in general.

Plant yield and quality are complex characters depending upon a number of genetic factors interacting with the environment. The development of superior variety is based on magnitude of genetic variability in the base population and extent of heritability of desired character. The limited variability in durum wheat owing to its evolutionary history is of great concern in improving its yield potential. Yield enhancement could be obtained indirectly by improving yield components which are controlled by a number of genes with small additive effect which are called as Quantitative Trait Loci (QTLs). Ability of the wild progenitor species to improve yield and quality characters is well known.Thus, there is a scope to improve the protein content and other quality parameters and quality of various products made from durum wheat through the transfer of alien genes from the related wild progenitor species.

Mutation breeding is one of the innovative methods in plant breeding. Hugo de Vries introduced the term mutation in the late 19th century. Since the induction of artificial transmutation of gene by X-rays on Drosophila by Muller in 1927, the field of mutation breeding has gained improvement. Cowpea is an important food legume of the tropics and subtropics.Improvement of cowpea by conventional breeding techniques is time taking and involves constraints such as small flower, difficult crossing, poor seed setting and less number of seeds per pod. Mutation breeding in recent times as an effective tool for crop improvement and an efficient means supplementing existing germplasm for cultivar improvement in breeding programs. Cowpea has immense scope for genetic improvement for various qualitative and quantitative characters besides widening the genetic base through induced mutagenesis. This book will be definitely helpful for researchers, teachers as well as postgraduate students in standardizing the studies on mutation breeding in cowpea. This book deals with the study of induced genetic variability through gamma rays and EMS in two distinct varieties.

Wheat (Triticum aestivum) is king of cereals and it is the staple food of the people of Pakistan. To understand the genetics of drought tolerance two promising elite lines V- 04189 and V-03138 were crossed to develop F1, F2 and back cross generations (BC1 and BC2). Six generations (P1, P2, F1, F2, BC1 and BC2) were raised under water stress conditions. Analysis of variance showed significant difference among generation means which indicated presence of sufficient genetic variability. Hybrid vigor was observed in most of the cases except plant height, spike length and flag leaf area. Generation means analysis revealed presence of additive [d], dominance [h] and epistasis genetic effects in the inheritance of traits. Two parameter model [md] provided the best fit for spike length, number of tillers per plant relative water contents and excised leaf water loss which shows the presence of additive genetic effect is prominent with simple inheritance while, [ml] showed best fit for grain yield per plant that indicates epistasis is involved in the inheritance of trait. The remaining traits exhibited higher parameter models and indicating the complex inheritance.
