Environmental Variability of Thousand Kernel Weight in Maize Hybrids of Different Maturity Groups

Thousand kernel weight (TKW) is an important yield component trait affected by the environmental conditions. This study’s objectives were to determine variability for TKW in 32 maize hybrids, sorted four FAO maturity groups (FAO300, 400, 500 and 600), compare 12 environments Croatia (six locations two years) according joint linear regression stability analyses across groups. In general, effects of environment, genotype, their interaction (GEI) significant. A three-factor ANOVA revealed greatest highly significant year effect, while location effect was non-significant all analysis did not detect any preferences with regard trends It indicates that Pannonian region included this study suitable evaluation genotypes belonging The seems be appropriate yield-component breeding due a high heritability GEI nature.
