Research investigation was carried out with 45 new hybrids of sweet sorghum developed by crossing 3 male sterile lines with 15 restorers in L × T mating design and were grown in randomized block design (RBD) with three replications during Kharif-2019. Parents RSSV-355, RSSV-512, RSSV-454 and RSSV-498 were observed as good general combiners for juice yield and its contributing traits. Among the lines, CMS-1409 has been observed best general combiner for juice yield and its contributing traits. Out of 45 hybrids, 14 hybrids recorded significant positive SCA effects, among which, cross combinations CMS-1409 × RSSV-499, CMS-185A × RSV-350 and CMS-185A × RSV- 498 exhibited high sca effects for juice yield, with high SCA effects for its contributing characters. Based on per se performance, GCA effects of parents, SCA effects of hybrids and heterotic performance for yield, the cross combinations viz., CMS-1409 × RSSV-512, ICMS-479 × RSSV-355 and CMS-1409 × RSSV-499, CMS-1409 × RSSV-498 and CMS-1409 × RSSV-355 appeared to be the most promising.

Combining ability, Sweet Sorghum, Juice yield, SCA effects

The parents RSSV-355, RSSV-512, RSSV-454 and RSSV-498, were observed good general combiners for juice yield and its contributing traits. Among the lines, CMS-1409 has been observed best general combiner for juice yield and most of its contributing traits. Out of 45 hybrids, 14 hybrids recorded significant positive sca effects, among which, cross CMS-1409 x RSSV-499 (high x low), CMS-185A x RSV-350 (low x high) and CMS-185A x RSV-498 (low x high) combinations exhibited high sca effects for juice yield with high sca effects for juice yield contributing characters.
