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.
