Book Description
Cowpea (Vigna unguiculata (L.) Walp) is an important food legume cultivated in many parts of the world covering Asia and Oceania, Middle East, Southern Europe and Central and South America. It constitutes a major source of dietary protein, starch, minerals and vitamins for many poor families especially in Africa. The cowpeas grown in different parts of the world vary widely in seed colour and type, and preferences change from region to region. These varying preferences necessitate the need to develop cowpea varieties with different characteristics as no single variety can be suitable for all regions. The need to have a better understanding of the genetics of pigmentation in cowpea therefore becomes essential. This book presents a holistic approach to the understanding of the genetics of pigmentation in cowpea with a view to elucidating the inheritance pattern of pigmentation in plant, flower and seed. This would be useful to geneticists and breeders in developing suitable strategies for the breeding of cowpea varieties that suit the varying needs of consumers.

Book Description
The book 'Genetics of cowpea' is a compilation of research findings on the study of morphological traits of cowpea (Vigna unguiculata [L.] Walp.). The inheritance pattern of some qualitative traits, such as purple pigmentations on the vegetative parts of the plant, flower colour, pod colour, seed colour, shape and texture, plant habit, and number of branches; and some quantitative traits, such as days to flower, days to maturity, pod length, peduncle length and seed weight are discussed. These traits exhibited monogenic, digenic and multigenic patterns of inheritance with various types of gene interactions which include dominance, complementarity, epistatis, etc. Some of these coloured parts of the plant showed close association with each other which could either be as a result of pleiotropy or linkage. The literature cited in the text is given at the end of the book. The book will meet the needs of university students, plant breeders and researchers.

Book Description
This authored book gives insight into the morphology, physiology, genetics, plant protection and biotechnology of three important arid legumes, viz., moth bean, cowpea and horse gram. There are seven chapters for each crop that provide in-depth information on cultivation, genetic improvement, plant protection measures, management of physiological and abiotic stresses along with related genetic markers and biotechnological advances pertaining to these legumes. The chapters present research findings and brief reviews concerning the advances made in the improvement of these legumes.Legumes are utilized as pulses or grains aiding as an important source of protein for both human and animal consumption and also provide raw materials to the food and feed industries. They are also valuable for soil building, improving soil quality and biological nitrogen fixation. Physiology and genetics provide an inimitable source of information on the distinct aspects of basic and applied legume research for general readers, students, academicians and researchers. Arid legumes are crops characterized by inherent features and capabilities to withstand adverse and harsh climatic conditions, significantly replenish the soil, as well as provide protein and micronutrients. Adaptability to several stresses including drought makes them key to agriculture in areas receiving scanty rainfall. This comprehensive book disseminates significant information on the genetic diversity, cultivation, manipulation through mutagenic techniques, molecular biology and other breeding techniques. The book, therefore, is of importance to teachers, researchers and policymakers who are interested to acquire knowledge about moth bean, cowpea and horse gram. It also serves as an additional reading material for MSc and PhD students of agriculture and environmental sciences. The book is also useful to national and international agricultural scientists and policymakers.

Book Description
Cowpea (Vigna unguiculata) is a warm-season legume that is primarily cultivated for protein rich grain. Seed size is an important breeding target that distinguishes most domesticated crops from their wild relatives and is a particularly important trait for the grain legumes. This dissertation describes efforts to breed cowpea varieties with larger seeds using marker-assisted approaches to breeding. The first chapter of this dissertation describes the development of a consensus genetic map of 1,107 molecular markers which was constructed by analyzing bead-assay genotype data from 13 experimental populations. The content and organization of the cowpea genome was also compared to the genome of soybean (Glycine max) to describe regions of synteny. The second chapter utilizes the genetic map, legume synteny, and phenotypic information collected from field and greenhouse trials to develop associations between allelic variation and the inheritance of seed size. Many of the regions of the cowpea genome important for seed size were found to be syntenic with regions of the soybean genome that were previously associated with the inheritance of seed size. These marker-trait associations are applied in the third chapter to breed cowpea varieties with up to 52% larger seeds which was accomplished by introgressing a rare Mozambican haplotype into the genetic background of a California blackeyed pea. Preliminary field screening identified introgression lines that also performed well for other important agronomic traits including yield, maturity, and plant architecture. The introgression lines developed in this work could be used as parents for deploying large seed size in other pedigrees and could be studied to better understand the impact of seed size on nutritional content and agronomic performance.

Book Description
Research data is expensive and precious, yet it is seldom fully utilized due to our ability of comprehension. Graphical display is desirable, if not absolutely necessary, for fully understanding large data sets with complex interconnectedness and interactions. The newly developed GGE biplot methodology is a superior approach to the graphical analys
