    Abstract

    The nature and magnitude of gene effects for several quantitative and qualitative characters were estimated in 2 commercial hybrids of grain sorghum [Sorghum bicolor (Linn.) Moench]. Dominance and dominance x dominance type of non-allelic interactions were found to play a significant role in the expression of heterotic manifestations in both the hybrids. The magnitude and to some extent even the nature of gene effects governing heterosis for various characters were found to differ when estimated over the 2 years. Gene effects should hence be studied in different environments (over years and locations) so that the influence of the environment is precisely estimated before chalking out breeding strategies.
