Abstract
Feeding assay of F2 and F3 seeds, derived from a cross between bruchid resistant wild greengram Sub2 and a bruchid susceptible high yielding cultivar B1 revealed that bruchid resistance in greengram is dominant and governed by a few major genes (probably two) with some modifiers. A single dominant gene is responsible for the production of purple coloration in the hypocotyl region at the seedling stage of greengram. Involvement of two or more genes along with the effects from environment was observed for the traits like leaf lobation, leaf vein colour, seed lusture and seed shape. No particular seed coat colour or phenotypic traits was found to be associated with the bruchid resistance. Significant and positive correlation was there between seed weight and bruchid susceptibility.
