Abstract:
Twenty genotypes of Indian mustard were evaluated for seed yield and its seventeen yield components for correlation and path coefficient analysis. The seed yield per plant had significant and positive correlation with plant height, number of primary branches, number of secondary branches, silique on primary branches, silique on secondary branches, silique on primary mother axis, biological yield per plant and physiological maturity at both genotypic and phenotypic levels. Among the component traits, biological yield per plant had significant and positive association with number of primary branches as well as number of secondary branches, silique on primary branches, siliqueon secondary branches and silique on primary mother axis at genotypic level. Further, path coefficient analysis of seventeen yield contributing characters clearly indicated that number of primary branches as well as biological yield per plant showed the highest positive direct effect on seed yield followed by harvest index, test weight, length of siliqua, silique on primary mother axis, which indicated positive direct effects in descending order and other characters contributed indirectly towards seed yield in Indian mustard.
