“…The table showed that the mean sums of squares due to GCA and SCA for all characters under study were highly significant (p ≥0.01) indicating the prevalence of both additive and dominant gene action. The influence of both type of gene action also reported by Hemlatha et al (2014), Patel et al (2016), Ali et al (2020) and Scaria et al (2020). Kamal et al (2023) reported non-significant mean squares for yield and component traits.…”

“…These parents (Q2, Q3, and Q4) are good combiners for transfer of early maturity traits. Krupakar et al (2013), E1-Shamarka et al (2015 and Patel et al (2016) also reported significant negative gca effects for these traits. When it comes to PH and EH, significant negative gca effects were Environment Conservation Journal 2020) also reported significant negative gca effects for plant and ear height.…”

In the present study twenty-eight hybrid combinations resulting from the half-diallel mating of eight quality protein maize (QPM) inbred lines were chosen in order to examine the potential to combine and gene activity for ten yield and component attributes. As part of the All India Coordinated Research Project (AICRP) on maize during the kharif-2020 season, the experiment was done at the research farm of college of Agriculture, Odisha University of Agriculture & Technology (OUAT) Bhubaneswar, using a randomized complete block design replicated thrice. Every observation recorded was subjected to statistical evaluation and it was revealed that the mean squares derived from the general combining ability (gca) and specific combining ability (sca) were highly significant (p ≥0.01). Estimates of sca effects were greater than that of gca effects for all of the variables used in the study, suggesting to the predominance of dominant gene action. The inbred lines Q4-DQL 2221-1-1(833.792), Q2-DQL 2099 (517.658) and Q3- DQL 2159 (350.325) shows high gca effects for yield and its attributing traits due to more additive gene action thus identified as good general combiners for yield. Twelve of the twenty-eight crosses showed significant (p ≥0.01 and 0.05) positive sca effect on grain yield. The best experimental crosses for grain yield based on per se performance and sca effects were Q2 x Q8 (2106.748), Q1 x Q6 (2053.048), Q3 x Q7 (2027.082), and Q3 x Q6 (1719.884).

“…Positive heterosis for green ear yield indicates the yield advantage of hybrids over the check Madhuri. Previous workers reported significant heterosis for GEY in positive direction (Melani and Carena 2005, Nepir et al 2015, Patel and Kathiria 2016, Ghosh et al 2018, Tulu et al 2018, Ali et al 2019. Whereas, only 13 hybrids showed significant positive standard heterosis for sugar content indicating the scope for use of more genetically divergent parents for better realization of higher heterosis for this trait(Table 1).…”

Forty two experimental hybrids generated through full diallel mating were evaluated in Randomized Block Design during kharif 2019 to study the magnitude of heterosis in sweet corn. Mid-parent heterosis ranged from -21 to 258 for DEW; -25 to 2 for GFW; 3 to 229 for GEY and standard heterosis ranged from 2.13 to 134.95 for DEW; 82.93 to 317.07 for GFW; -15.70 to 68.40 for GEY. Green ear yield exhibited positive significant correlation of mid-parent and commercial heterosis with NKPR, DEW and GFW in common, while no significant association between GEY and TSS was observed. The crosses KH1831 × SC Syn, SC Syn × SC Sel 2 and SC Sel 2 × SC Syn manifested highest mid-parent heterosis for de-husked ear weight, green ear yield and green fodder weight thus utilizing these hybrids in breeding programmes will serve for dual purpose of yield with fodder.
