Study of maize yield stability with nonparametric methods

High and stabile yield in different production environments is priority maize breeding. New statistical methods are constantly being sought to accompany analysis of variance, order achieve more reliable hybrid assessment. In this study nonparametric stability applied assess GxE interaction for 36 commercial hybrids. The experiment was set up at five locations Serbia three years according the Randomised complete block design replications. Yield investigated genotypes analysed by parameters Si (1), (2), (3), (6) TOP RS. Analysis variance identified highly significant F values all experimental factors. Bredenkamp method confirmed existence non-crossover interaction, yield. Hybrid ZPH15 achieved most stable based on (1) (2). According parameter (3) it ZPH5, while ZPH34. highest overall ZPH36 (11.18 t ha-1), which quite unstable (rank 24 (2)), very 34 (6)). hybrids had average yields. total, ZPH23 best rank (15.93). Based parameter, (yield), followed ZPH11, ZPH20, ZPH21 ZPH9. However, RS revealed that hybrid, so taking into account both productive hybrid. research, selecting new particular environment. case identical value, genotype with lowest value should be selected. can used as alternative selection moderate high stability.
