Abstract

An experiment was conducted to exploit heterosis in F1 hybrids of sweet sorghum (Sorghum bicolor L.) and to identify parents with desirable genetic effects with respect to single-cut green fodder yield and its component traits. 48 F1 hybrids were evaluated to assess general and specific combining ability and gene action governing the green fodder yield and its attributing traits. Analysis of variance revealed the presence of sufficient variation in the experimental material. The SCA variance was greater in magnitude than GCA variance for most of the traits under study indicating predominance of non-additive gene action in the genetic control of those traits. Line 185A and testers RSSV138-1, RSSV466 and RSSV404 emerged as good general combiners for single-cut green fodder yield. Based on sca effects, 185A x RSSV466, 185A x RSSV138-1, PMS71A x RSSV138-1 and PMS71A x RSSV404 were identified as good specific combiners for green fodder yield and its attributing traits.185A x RSSV466 recorded maximum singlecut green fodder yield with 12.53 per cent heterosis over the best check CSV30F.
