Heterosis is a quantifiable, trait-dependent and environment-specific phenotype, and the response of parental lines and their hybrids to environments resulted in various levels of heterosis hence, conformation of standard heterosis in maize hybrids is essential to exploit them commercially and thereupon uplifting their production potential. Therefore, the present study was designed in order to deduce the hybrid potential and useful heterosis to magnify the production and productivity of maize. Thirty single cross hybrids along with four standard checks were evaluated at three location using randomized block design during rabi, 2022-23. Analysis of variance due to mean square of genotype exhibit significant difference for all the studied traits indicating the presence of sufficient variation. Thirteen hybrids recorded the higher grain yield than the best check Bio 9544 and GP 329×GP 83, GP 82×GP 83 and PFSR 145×GP 69 were the top performers. Seven hybrids (GP 329×GP 83, GP 82×GP 83, PFSR 145×GP 69, GP 329×GP 86, PFSR 393×GP 107, GP 329×GP 107 and PFSR 204× GP 107) exhibited the significant and positive heterosis over the best check hybrid. Hybrid PFSR 393×GP 86 for ear length, GP 329×GP 69 for ear girth, GP 329×GP 86 for number of kernel per ear and number of kernel per row and PFSR 393×GP 83 for 100 grain weigh reported the significant heterosis in desirable direction over best checks. The hybrid GP 329×GP 83 had higher yield potential and found to be early in maturity indicating its significance in developing potential early maturing maize hybrid. The identified promising hybrids could be endorsed for future breeding programme following the conformation of results by repeating the research across locations. Not Available |
