Genetic Analysis in Wheat

Genetic information, especially about the nature of combining ability and type of gene action governing inheritance of important traits are guidelines to a breeder in selecting parents for development of hybrids, varieties and lines. This book is about results of research conducted on non segregating generations (parents and F1s ) and selected segregating (F2) population derived from 12 elite bread wheat (Triticum aestivum L.) genotypes following line by tester mating system. Parameters such as days to flowering and maturity; plant height, number of tillers per plant; peduncle length; spike length; total biomass per plant; number of grains per spike; grain yield per plant; 100-grain weight; and harvest index were analyzed and moreover, rust resistance mechanism was also considered. The objective is to reveal information on extent of heterosis and inbreeding depression; nature of gene action; extent of variability and genetic advance; association of component traits with each other and grain yield; and the way the component traits affect grain yield and finally rust resistance mechanisms. The book is helpful to mid-level researchers and students who seek to know more about wheat.
