This book was released on 2012-08 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Analysis of antioxidant activity (AOA) of entries in the 2002 Regional Southernpea Cooperative Trial revealed not only significant differences among entries, but that entries with pigmented (black and red) seed coats were clustered among the highest, cream types were the lowest, while pinkeye and blackeye types were intermediate. Red colored peas were higher in antioxidant activity than black types. These findings provided strong evidence that compounds responsible for pigmentation were involved in AOA. The objectives of the present investigation were to investigate the inheritance of AOA in cowpea and further study the relationship between AOA and seed coat color. Four advanced selections, ARK95-356 (black), ARK98-348 (red), ARK96-918 (cream), and LA92-180 (cream), were crossed in a complete diallel mating design, generating F1, F1', F2, F2', BC1, and BC2 populations. Individual seeds were ground and samples were extracted in methanol and analyzed for AOA using the free radical 2, 2-Diphenyl-1-picrylhydrazyl (DPPH) method. Combining ability tests using Griffing's Method I Model I indicated presence of highly significant general combining ability (GCA), specific combining ability (SCA), and reciprocal (REC) and maternal (MAT) effects, with pigmented lines exhibiting positive GCA and MAT, while non-pigmented lines exhibited negative GCA and MAT. AOA in the F1 was not significantly different from the maternal parent, with seed coat color also resembling the maternal parent. Segregation for seed coat color was observed in the F2 and F2'. Additive, dominance, and epistatic effects were significant. The broad sense heritability estimate was 0.87. Minimum number of genes responsible for AOA was estimated at about five. Factors governing high AOA appeared to be the same as those responsible for seed coat color, with apparent pleiotropic effects. In conclusion, breeding for high AOA is possible using highly pigmented parental lines.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
