Abstract:
Rapeseed-Mustard is one of the most important oilseed crops in India. Yellow sarson (Brassica rapa L. var. yellow sarson), an important ecotype of rapeseed has higher oil content due to thin seed coat. The present investigation was conducted to analyze combining ability, heterosis and maternal effects for the yield traits in three Yellow sarson varieties (B9, YSH 401 and NRCYS 05-03) crossed in Complete diallel design (Griffing, 1956). Significant differences were observed for all the thirteen characters from the analysis of variance. ANOVA for Combining ability revealed that variation due to GCA, SCA and reciprocals were significant for various characters. Analysis made on the Hayman’s (1954) model exhibited maternal effects, which mainly accounted for the significant reciprocal effects for many characters. YSH 401 was the best general combiner while YSH401 x B9 was the earliest and best cross showing good mean performance for various yield traits showing high heterosis.
