ABSTRACT

A partial diallel analysis (S=7) involving 20 parents was studied in F 1 and F 2 generations in yellow sarson. The variances for general and specific combining ability were highly significant in both the generations. The estimated components of variance revealed that additive gene action was more important for days to flowering, days to maturity and plant height in both the generations. Primary branches/plant, secondary branches/plant, siliqua length and siliquae/plant showed additive gene action in F 1 but non additive in F 2. Non-additive gene action played a major role in genetic variation for seeds/siliqua and seed yield/plant in both the generations. Parental performance as judged by gca effects indicated that AJL4, AJL18, AJL19, AJL20, AJL55, AJL43 and YID 1 were promising genotypes. These genotypes may be used as potential source in hybridization programme
