Estimates of gene effects based on analysis of generation mean were obtained for nine traits in three crosses in castor (Ricinus communis L.): SKP-84 x DCS-94, VP-1 x DCS-94 and GEETA x GC-3. The study material includes P1, P2, F1, F2, BC1 and BC2 generations of these crosses.The individual scaling test and joint scaling test indicated that an additive-dominance model was adequate in three traits viz., length of main raceme, number of effective branches per plant and seed index in the cross VP-1 x DCS-94. The analysis showed the presence of additive, dominance and epistasis gene effects for the traits.However, to exploit both additive and non-additive gene action reciprocal recurrent or biparental mating procedure may be adopted for improvement of traits. Duplicate epistasis played a greater role than complementary epistasis. Key words:- Castor, Gene action, Generation mean, Polygenic traits, Scaling test

The concept of breeding cultivars with wide adaptation is itself well adapted by researchers. In fact, there are two broad categories of breeding strategies in crops: broad adaptation and location-specific adaptation. Considering the complexity of the growing environments in a country and the need to maximize yield, the strategy should be directed toward developing varieties with location-specific adaptation. Reliance on a few varieties renders crops growing highly vulnerable to pest and disease outbreaks. Varietal interactions depend on the environments, but these interactions involve the individual genotype's physiological and genetic traits. In order to identify physiological traits related with environmental factors, there is a need for an effective statistical procedure. Additive main effects and multiplicative interaction (AMMI) analysis is ideal for this task. An AMMI statistical analysis is introduced as a tool to separate and quantify the GxE associated with yield and physiological components. This technique uses better statistical analysis for GxE partition and the bi-plot graphs useful in analyzing which genotype "wins" in an environment.

Proteomic is now increasingly considered as useful technique to reveal genetic diversity among different bacteria isolates differentiating live pathogens from dead ones. This book, therefore, reveals proteomic diversity of thirty Xanthomonas oryzae pv. oryzae (Xoo) isolates, the causative agent of rice bacterial leaf blight disease in West Africa, using isozyme polyacrylamide gel electrophoresis (PAGE) analysis. The study revealed 23 isozyme loci in which SKDH produced 33.3-93.3 % polymorphism, EST and G6PH equally gave 40-96.7 % polymorphism within the Xoo isolates enzyme profile. Phylogenetic relationship among 30 Xoo isolates revealed two major genetic groups (Xoo-A and Xoo-B) with two subgroups each (Xoo-A1 and Xoo-A2) and (Xoo-B1 and Xoo-B2). The distinct pattern of each isolate suggested high level of genetic variation and frequent occurrence of mutants in Xoo isolates in different host cells. This information should especially be useful for rice breeders, rice pathologists, rice disease epidemiologists, rice biotechnologist and the scientific community aiming at development of durable Xoo resistant rice cultivars to different localities in West Africa.

Soil health has become a cause of concern for sustainable agricultural production in the new millennium. Use of high analysis fertilizers, heavy sulphur removal by the crops under intensive cultivation & neglect of S replenishment contributed to widespread S deficiencies. Sulphur deficiencies have been reported from 72 countries in the world. Sulphur has a great role in N-fixation by influencing active nodulation in legume & despite the relatively low S requirement of rice , the productivity of these staple food grains may drastically be reduced by an inadequate supply of S. Sulphur has the ability to benefit more than one crop in sequence due to it's significant residual response. Application of higher dose of phosphorus (60 kg P205 /ha ) and increasing levels of sulphur up to 40 kg S/ha proved to be the best in improving the growth, yield attributing characters, grain yield of green gram. Varying levels of residual fertility and basal dose of nitrogen application significantly improved the rice yield and yield attributes. The research data of this book makes it useful reference for researchers, under graduate and post graduate students of agriculture and farming community.

Taro (Colocasia esculenta L.) is one of the major staple root crops in different countries of the world.However, the yield potential is seldom realized, and among the yield limiting factors, soil fertility is one of the major factor affecting the yield of the crop. Thus, this book gives research result on 'Response Taro to Applied N and K Fertilizer Levels. Two types of fertilizers at different levels, i.e. K (0, 75, 150 and 225 kg ha-1) and N (0, 50, 100, 150 and 200 kg ha-1), were combined in factorial for the experimental study. The response of taro to N and K levels was assessed by examining growth and yield parameters. The result revealed that K had no significant effect on the growth and yield of taro, except for the corm dry weight. But N had significantly affected both the growth and yield of taro. The maximum yield (60.96 t ha-1) was obtained by application of 150 kg N ha-1. Economic analysis showed that the highest net benefit was obtained in treatment combination of 75 kg K ha-1 with 150 kg N ha-1. However, the marginal rate of return analysis was optimum when 100 kg N ha-1 was applied. Thus, 100 kg N ha-1 was found optimum for taro production based on this experiment.

Bacterial Leaf Blight caused by the bacterial pathogen Xanthomonas oryzae pv. oryzae (Xoo) limits rice yield in all major rice growing regions of the world, especially in irrigated lowland and rainfed conditions where predisposition factors favour disease development to epidemic proportions. Since bacterial pathogens are difficult to manage, development of host plant resistance is the most effective means of disease management.To combat the problem of resistance breakdown, pyramiding of resistance genes into different cultivars is being carried out. The present book deals with the gene specific marker for detection of BLB resistance genes in rice genotypes.

9052 руб.
Litter size is one of the most important traits in overall reproductive efficiency of breeding sows. The triat has low heritability, is measured only in females and is expressed relatively late. Genetic improvement for litter size is possible due to large enough direct additive genetic variance, the availability of records on many relatives and short generation interval. Litter size is affected by many environmental and genetic factors and interaction between them. The goal of this study was to determine covariance functions for litter size i.e. number of piglets born alive using random regression model. Further, the aim was to compare it with estimates of genetic components obtained by using repeatability and multiple-trait model.

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.

Since the middle of the 20th Century yield design approaches have been identified with the lower and upper bound theorem of limit analysis theory – a theory associated with perfect plasticity. This theory is very restrictive regarding the applicability of yield design approaches, which have been used for centuries for the stability of civil engineering structures. This book presents a theory of yield design within the original “equilibrium/resistance” framework rather than referring to the theories of plasticity or limit analysis; expressing the compatibility between the equilibrium of the considered structure and the resistance of its constituent material through simple mathematical arguments of duality and convex analysis results in a general formulation, which encompasses the many aspects of its implementation to various stability analysis problems. After a historic outline and an introductory example, the general theory is developed for the three-dimensional continuum model in a versatile form based upon simple arguments from the mathematical theory of convexity. It is then straightforwardly transposed to the one-dimensional curvilinear continuum, for the yield design analysis of beams, and the two-dimensional continuum model of plates and thin slabs subjected to bending. Field and laboratory observations of the collapse of mechanical systems are presented along with the defining concept of the multi-parameter loading mode. The compatibility of equilibrium and resistance is first expressed in its primal form, on the basis of the equilibrium equations and the strength domain of the material defined by a convex strength criterion along with the dual approach in the field of potentially safe loads, as is the highlighting of the role implicitly played by the theory of yield design as the fundamental basis of the implementation of the ultimate limit state design (ULSD) philosophy with the explicit introduction of resistance parameters. Contents 1. Origins and Topicality of a Concept. 2. An Introductory Example of the Yield Design Approach. 3. The Continuum Mechanics Framework. 4. Primal Approach of the Theory of Yield Design. 5.

Wheat (Triticum aestivum. L) is an important cereal, used as staple food and a good source of income in different countries. It is providing food to the one third of world's population. Wheat grain is highly venerated for a number of products. To feed the increasing population of world is a great challenge for researchers. The only way to tackle this challenge is to develop new genotypes with good yield potential and to enhance the potential of available genotypes. Breeding strategies for high potential varieties made on the basis of scientific and agronomic knowledge is good way to achieve this goal. Both quality and quantity of grain are important targets to improve. Genetic analysis is one of best tools to exploit the potential of species for application on commercial scale. It will not only enable us to feed humanity but also direct to use natural resources in proper way.

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.

Buffalo contributes 38.0 % milk in Asia. A total of 5033 records were utilized to investigate breeding efficiency (BE) and its various contributors. Effect of herd, period, season of calving, birth weight (BW), age at puberty (AAP), lactation yield (LY) and calving interval (CI) were analyzed. The effect of year and season of calving, lactation yield, calving interval, age at first calving and birth weight was found significant (P<0.001), while that of herd was non significant. BE correlated positively with BW and LY and negatively with AAP, AFC and CI. It was concluded that birth weight was the most significant contributor. In the succeeding study herd, sire nested into herd and parity had a significant effect on lactation yield, while the effects of year, season of calving, year x season and age at puberty x season was found non significant. It was suggested that the milk production ability of dairy buffaloes was improved by increasing birth weight and an increasing maturity. The last study suggested that heritability estimates of first lactation economic traits provided a better tool for selective breeding.

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.

Rice is the staple food for more than half of the world's population. Abiotic stresses such as drought and salinity limit rice production under rainfed environments, which comprise about 45 per cent of the global rice area. Increasing salinization of agricultural land causes toxic effects in plant development, primarily at the seedling level. Hence developing suitable rice genotypes for salinity prone areas will help us to stabilize the yield under the rainfed / water limited environments. Thus, there is a need for identifying, cloning and validating functional genes and transcriptional factors from our local plant species adapted to various biotic and abiotic stresses finger millet this will help us to have improved understanding of adaptive and general protective mechanisms conferring enhanced salt tolerance to plants.

Project Report from the year 2013 in the subject Audio Engineering, grade: 10, , course: ECE, language: English, abstract: Audio source separation is the problem of automated separation of audio sources present in a room, using a set of differently placed microphones, capturing the auditory scene. The whole problem resembles the task a human can solve in a cocktail party situation, where using two sensors (ears), the brain can focus on a specific source of interest, suppressing all other sources present (cocktail party problem).For computational and conceptual simplicity this problem is often represented as a linear transformation of the original audio signals. In other words, each component (multivariate signal) of the representation is a linear combination of the original variables (original subcomponents). In signal processing, independent component analysis (ICA) is a computational method for separating a multivariate signal into additive subcomponents by assuming that the subcomponents are non-Gaussian signals and that they are all statistically independent from each other. Such a representation seems to capture the essential structure of the data in many applications.Here we separate audio using different criteria suggested for ICA, being PCA (Principal Component Analysis), Non-gaussianity maximization using kurtosis and neg-entropy methods, frequency domain approach using non-gaussianity maximization and beamforming.

Epilepsy is a common and diverse set of chronic neurological disorders characterized by seizures. It is a paroxysmal behavioral spell generally caused by an excessive disorderly discharge of cortical nerve cells of the brain. Epilepsy is marked by the term "epileptic seizures". Epileptic seizures result from abnormal, excessive or hyper-synchronous neuronal activity in the brain. About 50 million people worldwide have epilepsy, and nearly 80% of epilepsy occurs in developing countries. The most common way to interfere with epilepsy is to analyse the EEG (electroencephalogram) signal which is a non-invasive, multi channel recording of the brain's electrical activity. It is also essential to classify the risk levels of epilepsy so that the diagnosis can be made easier.This study investigates the possibility of Extreme Learning Machine (ELM) and Continuous GA as a post classifier for detecting and classifying epilepsy of various risk levels from the EEG signals. Singular Value Decomposition (SVD), Principal Component Analysis (PCA) and Independent Component Analysis (ICA) are used for dimensionality reduction.

DNA typing of non-human DNA is a fast developing area of research and professional practice. The application of DNA typing in wildlife forensic science is one of these prime uses of DNA typing and is gaining increasing profile. The use of DNA profiling in wildlife forensic science falls into two broad areas: species testing and genetic linkage. Species testing answers the question ‘what species is this?’ and genetic linkage answers the question ‘did these two samples come from the same organism or population?’ Wildlife DNA Analysis: Applications in Forensic Science provides an accessible introduction to both of these key areas. Clearly structured throughout, the introduction highlights the different types of crime where these techniques are regularly used. This chapter includes a discussion as to who performs forensic wildlife examinations, the standardisation and validation of methods, and the role of the expert witness in this type of alleged crime. This is followed by a detailed section on the science behind DNA typing including the problems in isolating DNA from trace material and subsequent genetic analysis are also covered. The book then undertakes a comprehensive review of species testing using DNA, including a step-by-step guide to sequence comparisons. A comparison of the different markers used in species testing highlights the criteria for a genetic marker. A full set of case histories illustrates the use of the different markers used. The book details the use of genetic markers to link two or more hairs/feather/leaves/needles to the same individual organism and the software used in population assignment. The problems and possibilities in isolating markers, along with the construction of allele databases are discussed in this chapter. The book concludes with evaluation and reporting of genetic evidence in wildlife forensic science illustrated by examples of witness statements. •An accessible introduction to this fast developing area of research within forensic science •Case studies throughout to link theory and practice and to highlight the use of DNA testing in species testing. •Covers both crimes against wildlife and offences where wildlife can provide vital evidence •Assumes only a basic background knowledge of DNA •Includes a comprehensive review of species testing using DNA, including a step-by-step guide to sequence comparisons

Wheat encounters severe salt problems in comparison to rainy season crops because of high salt concentration which is built up in the root zone owing to high crop transpiration or by the use of saline water which adversely affects the growth of plant due to osmotic effects, ionic toxicity, nutritional imbalances and physico-chemical degradation of soil. Although reclamation is a solution to this problem but scarcity of irrigation water, financial constraints and lack of drainage facility hampers its implementation. In such an eventuality, breeding for salinity tolerance is the only admirable approach. Available information on genetic architecture of yield and it's contributing characters of bread wheat for salinity conditions is very less; thus it is necessary to study the genetics for yield and related characteristics and their inheritance under salinity conditions. The ensuing investigation were undertaken to analyse three crosses of wheat including salinity tolerant parents under saline and normal environments with the relevant objectives like estimation of the magnitude of gene effects for yield and its contributing characters in three crosses of wheat for improving tolerance.

The fruit provide two MJ per kg/wet weight of ripe perianth and contain high levels of carbohydrates, protein, starch, calcium and vitamins. Jackfruit has diverse medicinal uses especially for anti-oxidant, anti-inflammatory, antimicrobial, anti-cancer and anti-fungal activity. MatK (maturase K) genes are fast evolving, highly variant regions of plant chloroplast DNA that can serve as potential biomarkers for DNA coding and also in generating primers for plants with identification of unique motif regions. Advances in the genetic markers such as RFLP and PCR based methods are more reliable for identification of genetic diversity than morphological markers, although each technique has advantages and limitations. The objective of this research work was to estimate the level of genetic diversity and to assess genetic relationships among six varieties of jackfruit using 'matK gene' based on PCR technique and RFLP markers. The partial sequence of the 'matK' gene of six different Artocarpus varities was used in the analysis. The size of amplified products was approximately 700 bp. After sequencing and sequence editing, sequence information on a 674 bp region was finally obtained for analysis. The alignment of sequences revealed two haplo...

Mark Stoneking An Introduction to Molecular Anthropology

10029.31 руб.
Molecular anthropology uses molecular genetic methods to address questions and issues of anthropological interest. More specifically, molecular anthropology is concerned with genetic evidence concerning human origins, migrations, and population relationships, including related topics such as the role of recent natural selection in human population differentiation, or the impact of particular social systems on patterns of human genetic variation. Organized into three major sections, An Introduction to Molecular Anthropology first covers the basics of genetics – what genes are, what they do, and how they do it – as well as how genes behave in populations and how evolution influences them. The following section provides an overview of the different kinds of genetic variation in humans, and how this variation is analyzed and used to make evolutionary inferences. The third section concludes with a presentation of the current state of genetic evidence for human origins, the spread of humans around the world, the role of selection and adaptation in human evolution, and the impact of culture on human genetic variation. A final, concluding chapter discusses various aspects of molecular anthropology in the genomics era, including personal ancestry testing and personal genomics. An Introduction to Molecular Anthropology is an invaluable resource for students studying human evolution, biological anthropology, or molecular anthropology, as well as a reference for anthropologists and anyone else interested in the genetic history of humans.

Maize is one of the most important cereal crops in the World's agricultural economy both as food for humans and feed for animals and poultry. Maize is known as "Queen of Cereals" due to its higher yield potential compared to other cereals. In India it is the third most important food crop after rice and wheat. The demand for maize is increasing day by day in India, owing to the increased demand for poultry and cattle feed and for the same reason it is also emerging as an important cereal crop in India. In crop plants, the physiological basis of dry matter production is dependent on the source-sink concept, where the source is the potential capacity for photosynthesis and the sink is the potential capacity to utilize the photosynthetic products. Hence, for improving attainable crop yields the knowledge of yield forming physiological processes such as source-sink relationships is required. Many studies have been conducted on source-sink relationship in different crops including maize to understand this phenomenon towards maneuvering such crops. Since, maize being the sink limiting crop, it is important to study the source-sink relationship to improve the sink capacity and maize yield

Since the middle of the 20th Century yield design approaches have been identified with the lower and upper bound theorem of limit analysis theory – a theory associated with perfect plasticity. This theory is very restrictive regarding the applicability of yield design approaches, which have been used for centuries for the stability of civil engineering structures. This book presents a theory of yield design within the original “equilibrium/resistance” framework rather than referring to the theories of plasticity or limit analysis; expressing the compatibility between the equilibrium of the considered structure and the resistance of its constituent material through simple mathematical arguments of duality and convex analysis results in a general formulation, which encompasses the many aspects of its implementation to various stability analysis problems. After a historic outline and an introductory example, the general theory is developed for the three-dimensional continuum model in a versatile form based upon simple arguments from the mathematical theory of convexity. It is then straightforwardly transposed to the one-dimensional curvilinear continuum, for the yield design analysis of beams, and the two-dimensional continuum model of plates and thin slabs subjected to bending. Field and laboratory observations of the collapse of mechanical systems are presented along with the defining concept of the multi-parameter loading mode. The compatibility of equilibrium and resistance is first expressed in its primal form, on the basis of the equilibrium equations and the strength domain of the material defined by a convex strength criterion along with the dual approach in the field of potentially safe loads, as is the highlighting of the role implicitly played by the theory of yield design as the fundamental basis of the implementation of the ultimate limit state design (ULSD) philosophy with the explicit introduction of resistance parameters.
