Correlation and Path Analysis for Seed Yield and Its Component Traits in Indian Mustard (Brassica juncea L. Czern and Coss.)

Abstract

A study for 17 agronomic traits was conducted to evaluate correlation and path analysis in Brassica juncea L. Czern and Coss. Ten lines with diverse genetic makeup and their crosses which were performed in half diallel fashion were grown in Randomized Block Design in three replications during rabi season (2021-22). At phenotypic and genotypic level, seed yield per plant exhibited significant positive correlation and positive direct effect on seed yield via plant height, total siliqua per plant and biological yield per plant in both F1 and F2 generations, while number of primary branches, seeds per siliqua and oil content showed negative direct correlation with seeds yield per plant at genotypic and phenotypic level in both F1 and F2 generations. The results of the study concluded that plant height, total siliqua per plant and biological yield per plant exerted high correlation and direct effect on seed yield per plant generations. Hence, these characters might be considered for selection and in improvement of seed yield of mustard genotypes.
