Avoid the common mistakes References. Al-Jiboury HA, Miller PA, Robinson HP (1958) Genotypic and environmental variances and covariances in an upland cotton cross of ... 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.
