High heritability coupled with high genetic advance as percentage of mean and estimates of genotypic coefficient of variation were higher for number of secondary branches per plant in all the environments of Indian mustard have consequent chancesn of improving these traits through simple selection, indicating additive gene action may be responsible for expression of these traits. The correlation and path analysis studies showed that for developing new plant type in Indian mustard should be multiple primary and secondary branches, more number of siliquae on main raceme, plant height, high biological yield and seed yield which improve the productivity of plant, while in addition to these traits large seed size should provide more emphasis for developing plant types in Indian mustard under different environments. A subsequent genetic diversity among the genotypes was observed.
