Book Description
Yield data from three experiments of maize single cross trials grown at 5 to 8 locations in 1994, 1995, and 1996 were analyzed for stability using regression methods. Only single crosses grown in all locations and years (environments) were included in the analyses. Effects for environments, genotypes, genotype x environment, heterogeneity of regression (slopes), and deviations from regression were tested for significance. Slopes and deviation from regression were calculated for each single cross and slopes were tested for equality to 0.0 and 1.0. Slopes sums of squares were subdivided into sums of squares due to concurrence and non-concurrence. Subsets of each experiment were also analyzed to examine whether stability changed in environments stratified by mean yield levels or by years. The analysis of one experiment revealed significant differences among single cross slopes and non-concurrence. The other two experiments were unusual in that the tests for heterogeneity of slopes were not significant.

Estabilidade de desempenho de producao e uma caracteristica desejavel em hibridos de milho (Zea mays L). Muitos metodos tem sido propostos e usados para medir a estabilidade da producao em estudos aplicados. O objetivo do estudo foi determinar a producao relativa de graos e estabilidade de producao de graos entre grupos de simples cruzamento de hibrido de milho produzidos de linhas congenitas selecionadas de milho. O metodo usado foi o de Eberhart e Russel para desempenhar a analise de estabiliade de variancia e parametros da estabilidade calculada.
