Forty six hybrids of sunflower obtained from 5 cms lines (2A, 5A, 207A, 234A and 821A) and 19 genotypes were evaluated for their days to 50% flowering, plant height, head diameter and seed yield/plant. The hybrid 207 A x 234 B and 234 A x TNAUSUF 15/1 recorded 142 and 116 percent as standard heterosis, respectively for seed yield per plant. Therefore, these two hybrids could be recommended for large scale evaluation.
