The present investigation was carried out at the Research Fields, ICAR-Indian Institute of
Oilseeds Research, Rajendranagar, Hyderabad, Telangana, India. The material for present
study consisted of twenty newly developed mono and multi headed restorer lines including
CMS lines. The data for agronomic and yield traits i.e. days to 50% flowering, days to
physiological maturity, plant height, head diameter, volume weight, 100 seed weight, seed
yield per plant oil content and oil yield was recorded. The analysis of variance revealed
significant differences among the genotypes for almost all characters which favour the
selection. Associations among characters especially indicated that among the seven traits
studied, seed yield per plant had a highly significant positive association with head diameter
and significant negative correlation with days to 50% flowering and days to maturity. The
genotypes, COSF-6B, COSF-7B, RGP-11-P1-S2, RGP-58-P4-S1-1 and RGP-46-P3 were
identified as the most important genotypes for different traits and should be utilized in
heterosis breeding programme to realize high heterosis for yield and yield contributing
traits.
