Exploitation of heterosis and assessment of combining ability by using half diallel analysis over the three environments was done at the Main Maize Research Station, Anand Agricultural University, Godhra during 2016-17. The experimental material comprised of ten inbred lines, 45 hybrids and two standard check hybrids viz., GAYMH 1 and HQPM 1 were used to evaluate and followed Randomized Complete Block Design with three replications under three environments (E1, E2 and E3). The observations were recorded for 20 characters viz., initial plant stand, days tasselling, tassel blasting, days silking, Anthesis Silking Interval (ASI), leaf rolling, leaf senescence, plant height, ear height, days to brown husk, final plant stand, ear length, ear girth, kernel rows per ear, kernels per row, shelling percentage, 100 kernel weight, kernel yield per plant, kernel moisture and proline content.EnglishThesis
