Study on correlation coefficient, direct and indirect effect of various characters on seed yield and quality traits in Indian mustard [Brassica juncea (L.) Czern and Coss]

Abstract

A study was conducted to evaluate correlation and path analysis of 18 yield and quality characters in Indian mustard (Brassica juncea). 15 lines and 4 and their crosses were evaluated during 2023-24 in randomized block design with three replications at CSAUA&T Kanpur. At phenotypic and genotypic level, seed yield per plant exhibits significant and positive correlation with harvest index in both F1 and F2 generation. High direct positive impact on seed yield at phenotypic level exerted by harvest index and biological yield/plant in both F1’s and F2’s. At genotypic level high direct positive impact on seed yield exerted by harvest index, biological yield/plant in F1 and by oil content, plant height in F2 generation. Hence these characters given more weightage in selection programme of high yielding genotypes.
