Genetic Correlation and Path Coefficient Analysis of Yield Attributing Parameters in Indian Mustard

Indian mustard (Brassica juncea L. Czern. & Coss) is a natural amphidiploid which the greatest pre-dominating crop of oilseed Brassica group. A study was undertaken to estimate genetic variability, correlation and path coefficient analysis yield its contributing traits in 75 genotypes grown Randomized Block Design with two replications. The variance highly significant for all characters investigated. All thirteen were showed higher values phenotypic coefficients variation than genotypic variation. heritability broad sense estimated characters. High value indicates that it may be due contribution components. coupled high advance as percent means recorded days 50% flowering, plant height (cm), number(s) secondary branches per plant, length main raceme siliquae seed (g), plot harvest index biological indicated predominance additive gene action inheritance these traits. direct positive correlations yield, numbers primary branches, on documented. Whereas, maturity negative grain yield. Seventy-five genotypes, included grouped into 6 clusters. maximum inter cluster D2 III IV are not so closely related while I related. It apparent therefore; various clusters differ significantly regards their relative distance from values. This makes clear have wide range diversity used hybridization programme develop yielding cultivars.
