Abstract
The present investigation consisted of 53 entries including 36 hybrids along with 12 parents, 3 testers and 2 checks viz., PHM-3 and Pratap Raj Hybrid Maize 1095 were evaluated in three different environments during Kharif 2023. The estimates of standard heterosis for grain yield and its attributing traits along with quality traits showed that hybrid L4ÃT3 exhibited maximum estimates of significant positive standard heterosis for grain yield per plant E1 (9.80%), in E3 (9.31%) and on pooled basis (13.67%). This hybrid also possessed maximum significant estimates of economic heterosis for ear girth (7.92%) in E1 and protein content in E1 (7.88%) while negative economic heterosis for ear height (-17.20%) in E1 environment. For other agro-morphological traits, hybrid L9ÃT1 for 100-grain weight (6.50%), L1ÃT1 for ear height (-8.44%) and L8ÃT3 for number of grain rows per ear in E3 (8.21%) and L8ÃT1 (6.90%) for harvest index showed maximum economic heterosis across the environment. L4ÃT3 exhibited maximum estimates of significant positive standard heterosis suggesting that hybrid may be exploited before commercial release for confirmation of its superiority.
