Abstract

Fifty-five entries comprising ten parents and their 45 hybrids of Brassica campestris L. var. sarson Prain were studied for phenotypic and genotypic correlation by path analysis. In general, correlation coefficients at genotypic and phenotypic level showed the same trend and genotypic correlations were of greater magnitude than phenotypic ones. Grain yield was significantly associated with plant height, number of primary and secondary branches, length of main siliqua bearing axis, number of siliqua on main axis, siliquae per plant, days to maturity, grains per siliqua and 1000-grain weight. Path coefficient analysis showed that number of siliquae per plant is the important yield component followed successively by number of secondary branches and length of main siliqua bearing axis. Days to flower and plant height showed negative direct effect on grain yield. Based on present study, the requirement of an ideotype in yellow sarson have also been discussed.
