An attempt was made to assess the heterotic capability of inbred lines in F6 generation of a sorghum [Sorghum bicolor (L.) Moench] cross 3660 B x MR-750. Seventy-three inbred lines in F6 generation were crossed to 296A, a well-known male sterile tester to develop 73 derived F1s. The hybrids exhibited desirable transgressive segregation for grain yield and some hybrids were even better than cbmmercial check (CSH 5) for their per se performance. This implied that lines with improved heterotic capability could be found in progenies from cross of two elite lines in sorghum.
