Combining ability of some rapeseed (B. napus L.) varieties
The objects of the study were the combining ability (CA) of five rapeseed (B. napus L.) varieties, mode of inheritance of oleic and linoleic acid content in the F1 generation and components of genetic variability. Diallel crosses without reciprocals were made between five varieties. The plants used as mothers were turned male sterile by hand.Diallel analysis was done according to Griffing (1956) (Method 2, Model 1). The mode of inheritance was assessed according to Borojevi(c) (1965), while the analysis of components of genetic variability was done according to Jinks (1954). In the inheritance of both characters, positive heterosis, dominance of the better parent, dominance of the poorer parent and intermediacy were expressed. Additive components of genetic variability played the more important role in the inheritance of both character. In the process of inheriting seed oil content, dominant genes in the parents prevailed over recessive ones.
