Combining ability of parents and hybrids for juice yield and its attributing traits in sweet sorghum [Sorghum bicolor (L.) Moench]
An investigation was carried out to assess the combining ability and nature of gene action in respect of juice yield and itsattributing traits in 72 new hybrids of sweet sorghum developed by crossing 4 male sterile lines with 18 testers in Line × Testermating design and grown in Randomized Block Des...

| description | An investigation was carried out to assess the combining ability and nature of gene action in respect of juice yield and itsattributing traits in 72 new hybrids of sweet sorghum developed by crossing 4 male sterile lines with 18 testers in Line × Testermating design and grown in Randomized Block Design with two replications during kharif 2008. The variance among the linesin respect of their general combining ability was highly significant for days to 50 per cent flowering, nodes per plant and juiceyield, where as variance among testers was significant for juice yield. The variance due to line × tester interaction was significantfor all the characters indicating differential response of lines with different testers. SCA variance was relatively higher inmagnitude for all the traits indicating predominance of non-additive gene action in the genetic control of these traits. ICSA 38and ICSA 102 among the lines and ICSV 93046, E 36-1, ICSV 700, SEREDO and GD 65008 among the testers, were identifiedas good general combiners indicating their ability in transmitting additive genes in the desirable direction to their progenies.Highly significant sca effects were observed in most of the hybrids for all the characters studied and good specific combiners fordifferent characters involved parents with high × high, high × low, low × high and low × low general combinations |
