Abstract:
An investigation was undertaken to study correlation and path coefficient analysis for seed yield and its components among 20 genotypes of Indian mustard. The field experiment was conducted under timely sown condition in randomized block design with three replications at Nidharia farm, S.M.M. Town Post Graduate College, Ballia during Rabi season 2017-18. The data were observed on 11 characters viz. days to 50% flowering, number of primary branches, plant height, days to maturity, number of siliquae per plant, number of secondary branches, number of seeds per siliqua, biological yield per plant, test weight, harvest index and seed yield per plant. The seed yield per plant had positive and significant correlation with days to 50% flowering (0.284, 0.256), plant height (0.423, 0.405), test weight (0.590, 0.577) and harvest index (0.749, 0.746) at both genotypic and phenotypic levels. However, it had associationship with number of seeds per siliqua (0.278) at genotypic level only. Furthermore, path coefficient analysis of yield contributing characters clearly indicated that harvest index (1.277) showed the highest positive direct effect on seed yield followed by biological yield per plant (0.9511), days to maturity (0.1951) and number of secondary branches (0.1430). Observations suggest that these characters served the basis for selection in breeding programme for yield improvement in Indian mustard.
