Abstract:

A set of 15 rapeseed genotypes including five yellow sarson and ten toria genotypes, was evaluated following organic cultural practices during Rabi 2017-18 and Rabi 2018-19 to assess genotypic performance, genetic variability and character interrelationship. The pooled analysis of variance revealed significant variation due to genotypes, environments and genotype-environment. JYS14-2, PYS2012-1, JT13-1 and JT13-5 were found as promising genotypes. Analysis of genetic parameters revealed high heritability and genetic advance for days to 50% flowering, leaf size and main shoot length indicating that these three characters were under the influence of additive gene action. For these characters significant genotypic variation was observed. Correlation and path analysis exhibited that main shoot length and leaf size were the most important yield attributes for organic rapeseed breeding.
