The current research was conducted on fifty genotypes of Brassica juncea L. in order to evaluate the relationship of
seed yield with its component characteristics according to the path coefficient and correlation analyses at genotypic
and phenotypic levels. Genotypic correlations were found to be stronger compared to phenotypic correlations and
indicated a significant effect of genetic factors in the relationships between traits. Correlation analysis indicated that
branching characters, siliqua length and seed/siliqua were positively correlated with seed yield all the time, whereas
delayed maturity and more siliquae/plant were undesirable. Path coefficient analysis established biological yield/plant
and the harvest index as the main principal determinants of the seeds yield and other characters like siliqua length,
seeds/siliqua and branching played indirectly through these important components. The research identifies that selection
based on biological yield and harvest index, underpinned by principal reproductive traits, would be optimum for genetic
enhancement of seed yield in Indian mustard.
