Genotype by Environment Interaction on Early-Maturing and High-Yield Maize Hybrids

productivity in drylands Indonesia. Trials of hybrid maize candidates several locations and different seasons are highly needed to determine the stability prior commercial release. The objectives research were: (1) evaluate performance hybrids seasons; (2) assess early-maturing grain yield characteristics genotypes evaluated (3) that can be released as new superior/elite varieties. was conducted at 14 populations (7 locations, 2 seasons). Each population planted according randomized block design with 10 treatments 4 replicates, so 40 experiment units were obtained. Ten tested: six derived from a diallel cross high potential traits (G1, G2, G3, G4, G5, G6) elite varieties checks (G7 = SK, G8 ANM, G9 Pertiwi-x, G10 BISI-x). combined analysis variance (ANOVA) on revealed genotypes, environments (season, location, season x location), interactions (genotype season, genotype location) significantly affect harvest age per hectare (p < 0.01). G4 had an early (91.93 days) above average all (8.71 ton ha-1), also declared stable based three analyses: Finlay-Wilkinson, Eberhart-Russel, AMMI. Thus, is recommended variety early-maturing, high-yield, stable, broad adaptability traits. Doi: 10.28991/HEF-2023-04-01-05 Full Text: PDF
