Regressions and nature of associations among different quantitative traits in some interspecific hybrid derivatives of Indian mustard (Brassica juncea)

Abstract

Indian mustard (Brassica juncea) is an important oilseed crop next to groundnut in India. There is a wide gap
between demand and supply of edible oil. Major emphasis of Brassica breeding programme has been on improving
productivity in terms of seed yield and oil content. Yield is a complex character involving a number of components
which are quantitative in nature. Success of any breeding programme depends on the efficiency of selection of those
characters which have a maximum degree of positive influence with the other traits of interest. The present investigation
was undertaken to estimate the correlations among the traits, their direct and indirect effect on yield
