“…The estimates of σ 2 sca were more than σ 2 sca for all the traits studied and the ratio of σ 2 sca/ σ 2 gca is more than unity indicating non-additive gene action operating in the inheritance of yield contributing traits. Similar results have also been reported in sorghum by Mengistu et al (2020), Kumari et al (2018), Akata et al (2017), Sayed and Said (2016), and Aruna et al (2010). The findings of this study, such as non-additive genetic variance for grain yield and yield components, suggested that in early generations of sorghum, selection and accumulation of desired alleles for the enhancement of yield and yield components is likely to be effective.…”

“…The least heterotic effects were observed for days to 50% flowering, 100 seed weight, and fodder yield per plot, in contrast to these. Many researchers have observed significant positive heterosis for grain yield (Mengistu et al, 2020, Prateeksha et al, 2018, Aaref et al, 2016, Choudhari et al, 2016, Mindaye et al, 2016, Gite et al, 2015and Kalpande et al, 2015. .…”

Forty eight hybrids, utilizing six male sterile lines and eight restorers of Sorghum (Sorghum bicolor (L.) Moench) were evaluated for general and specific combining ability, variance components and standard heterosis. Among the lines ICSA 427 and ICSA 433 and testers ICSR 13009 and ICSR 13031 were found to be good general combiners for grain yield per plot and other yield contributing traits. The estimates of σ 2 gca and σ 2 sca suggested a non-additive genetic variance for all the traits studied. Most of the cross combinations showed higher magnitude of specific combining ability effects volving high × high (H × H) and high × low (H × L) combining ability effects of lines and testers for grain yield per plot and other yield contributing traits. The estimates of standard heterosis for grain yield per plot ranged from -49.53 and -50.46 (ICSA 435 × ICSR 13004) to 41.96 and 39.35 (ICSA 433 × ICSR 13043) over CSV-41 and CSH-16, respectively. Out of 48 cross combinations, six registered highly significant positive heterosis (over CSV-41 and CSH-16) for grain yield per plot.

“…Based on per se, sca effects and heterosis, the hybrid viz., CO(S) 28 x IS 18551, SPV 2424 x IS 9807 and CO 30 x SPV 759 exhibited significantly superior. In sorghum, this result was in consonance withUmakanth et al (2012),Kumari et al (2018),Sandeep and Biradar (2020),Mengistu et al (2020),Maiga et al (2021) andDiatta et al (2021).…”

Combining ability effects, heterosis and gene action of selected sorghum lines for yield and yield contributing traits were assessed. Twenty hybrids were synthesized involving five lines and four testers through L x T mating design. The hybrids, parents and check variety CO 30, were evaluated in a randomized complete block design with three replications and seventeen traits were recorded. The analysis of variance for combining ability revealed that the mean sum of squares due to general combining ability was significant for all the traits. The ratio of σ 2 gca / σ 2 sca revealed that non-additive gene action predominated in all the traits. On the basis of gca effects and per se performance of the parents viz., CO(S) 28, SPV 759 and IS 9807 exhibited significantly superior gca value and identified as a good general combiner for yield and yield contributing traits. The hybrids viz., CO(S) 28 x IS 18551, SPV 2424 x IS 9807 and CO 30 x SPV 759 showed significant specific combining ability effects, significant and higher heterosis of all the three types and per se performance for studied traits. These hybrids were identified as promising hybrids and can be commercially exploited for heterosis breeding programmes.
