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. 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.
