Abstract
An experiment was conducted to estimate heterosis in forty eight F1 hybrids of sorghum
[Sorghum bicolor (L.) Moench] with respect to grain yield and its components using six lines
and eight testers. The hybrids and their parents were evaluated to assess the combining
ability and gene action governing the traits by using line x tester analysis at Directorate of
Sorghum Research (DSR), Rajendranagar, Hyderabad during 2011-12. Non-additive gene action
was predominant for all the traits under study. The line 234 A ; testers CB 111 and CB 119
emerged as good general combiners for yield and its component traits. Based on sca effects,
three hybrids viz., 234 A x CB 127, 151 A x CB 126 and 3183 A x CB 119 were identified as
promising for good specific combiners for grain yield per plant and other traits. The hybrid
3183 A x CB 119 recorded maximum grain yield with 84.22, 69.78 and 26.93 per cent heterosis
over the mid parent, better parent and standard check, respectively.
