Correlation and path analysis in Indian mustard (Brassica juncea L.) in agro – climatic conditions of Jhansi (U.P.)

Abstract

An investigation was undertaken to study the correlation and path analysis of thirteen quantitative traits in 12 Indian mustard (Brassica juncea L.) germplasm lines. The experiment material was evaluated in a randomized block design with three replications. Analysis of variance ratios of all the characters were found highly significant. Coefficient of variation for GCV and PCV were found high for the following traits i.e. biological yield per plant, grain yield per plant and silliqua on main raceme. Biological yield per plant, silliqua on main raceme, grain yield per plant and number of seed per silliqua exhibited higher heritability and higher genetic advance. Correlation study revealed that biological yield per plant and silliqua on main raceme exerted high positive significant genotypic correlation with grain yield per plant and secondary branches per plant was found negatively correlated with grain yield per plant. path analysis revealed that days to 50 % flowering showed maximum positive direct effect however the highest indirect effect of this trait was exhibited through biological yield per plant.
