WebJensen (1970) suggested the use of diallel selective mating system (DSM) for genetic improvement of wheat. This is a modified form of recurrent selection which permits incorporation of several parents in the hybridization programme. This technique helps in breaking linkage blocks and creating vast genetic variability. WebDiallel mating design is used to evaluate several inbred lines in terms of combining ability variances and effects. Diallel cross refers to mating of selected parents in all … WebThe bulk or population method is considered one of the easiest and cost- and resource-efficient method of handling segregating populations. This method is useful when the parents used in creating breeding families (i.e., breeding populations) are of adapted types, and characters under consideration are polygenic in nature. mercure maldives kooddoo all-inclusive resort
