Abstract:

Screening of 230 F4 segregants of cross DC 615 (Susceptible parent) × Dharwad local (Resistant parent) along with checks (Dharwad local, DC 615, DC 15, DCS 47-1 and C 152) was carried out against bruchids (Callosobruchus maculatus) at the Department of Genetics and plant Breeding, University of Agricultural Sciences, Dharwad. Out of 230 segregants, 36 were highly resistant, 43 moderately resistant, 110 least susceptible, 34 moderately susceptible and 7 were found to be highly susceptible. The segregants F4-191, F4-199 and F4-162 were most superior in terms of per cent bruchid infestation, which recorded least values for actual weight loss, apparent weight loss, per cent seed damage, number of bruchids emergence after 45 days of infestation, per cent germination and seedling vigor after bruchid infestation.
