Abstract

Hybridization was effected between twenty lines and four testers and the resultant eighty F, hybrids were selfed to obtain F, seeds. The F,s and Fs were evaluated along with their parents. Observations were recorded for six quantitative traits namely days to maturity, plant height, number of capsules, test weight, seed yield and oil content. Two hybrids namely Si.3214 x SVPR 1 and TMV 6 x SVPR 1 recorded significant heterosis over standard check Co 1. In general, crosses with significant heterosis expressed significant inbreeding depression in F. The F, progenies of cross Si.3214 x SVPR I showed high heterosis with non-significant inbreeding depression for seed yield.
