This study assessed genotype x environment interaction effects on common bean yield and its components. Sixteen genotypes were evaluated in two agricultural years in two traditional cropping seasons in Rio Grande do Sul state -Brazil. The results obtained showed significant genotype x years interaction, which changed the genotype rank in each evaluation year. Path analysis showed that correlation between yield and its components was modified by the genotype x years interaction. These results suggest that more years of evaluation are necessary to obtain more reliable and useful estimates. KEY WORDS:Phaseolus vulgaris L., correlations, path analysis, cropping seasons. experiments carried out during the cropping appropriate season .

RESUMO O rendimento de grãos do feijão é afetado pela ocorrência de alta temperatura do ar, durante o período reprodutivo. Sendo assim, foi objetivo do trabalho avaliar a variabilidade genética do feijão para tolerância à alta temperatura do ar durante o período de pré-floração (R5) à formação de vagens (R7

RESUMO Com o objetivo de identificar a percentagem máxima
