Abstract
The expression of various characters in the hybrid depends upon the extent of genetic variation as well as genetic divergence existing between parents. Consequently a high yielding genotype nay not necessarily transmit its superiority in cross combinations. The present investigation was therefore. undertaken to estimate heterosis and combining ability for forage yield and its attributes in sorghum" The experimental material comprised of two male sterile lines (2219 A and 3660 A), 55 male parents and their 110 hybrids and two check varieties (M. P., Chari and GFS-3. The experiment was conducted in kharif 1988 at the Forage Research farm, Gujarat Agricultural University, Anand Campus, Anand, using simple lattice design with two replications. The material was dibbled in a row plots, the Inter and intra row spacing being 45 and 10 can respectively.
