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&#13;
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&#13;
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.</mods:abstract><mods:classification authority="lcc">Sorghum</mods:classification><mods:classification authority="lcc">Genetics and Genomics</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8061">1983</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>ICAR</mods:publisher></mods:originInfo><mods:genre>Article</mods:genre></mods:mods>
