Six genotypes of bush snap beans were evaluated in Anápolis, Goiás State, Brazil, during autumn-winter (25th May - 13th August, 2002) and spring-summer (12th November, 2002 - 10th January, 2003) seasons cultivation in an organic cropping system. The experimental design was of randomized blocks, with six treatments (breeding lines Hab 1, Hab 19, Hab 39, Hab 46 and cultivars Coralina and Turmalina), with four replications. All the genotypes resulted in higher yield during autumn-winter season. Cultivars Coralina and Turmalina were earlier in both seasons. 'Coralina' and Hab 39 showed the highest yields, higher than cv. Turmalina, but similar to the other breeding lines. During spring-summer season, 'Coralina' presented better results than Hab 46.
