Summary: | Common bean genotypes (Phaseolus vulgaris L.) belonging to the black group (evaluated in six environments) or to the 'carioca' group (evaluated in five environments) were tested for grain yield in the season of 2006/07, in the Santa Catarina State. The objective of this study was to evaluated the genotypic sensibility through predicted functions among the differences of the grain yield considering all the possible combinations among the studied environments. Significance absence for all tested genotypes of the black group indicates an insensitive behavior of these genotypes relatively to the pair of environment Chapeco vs. Lages. On the other hand, the Ponte Serrada environment intensely affected all the predicted functions relatively to the other environments regardless of bean group (black or carioca), indicating that these genotypes should be recommended for cultivation in stratified environments. Key words: phenotypic variance, BLUP, sensibility, grain yield bean. Genotipos de feijao (Phaseolus vulgaris L.) dos grupos preto (testados em seis ambientes) e carioca (testados em cinco ambientes) foram avaliados para rendimento de graos na safra agricola de 2006/07, no Estado de Santa Catarina. Desse modo, o objetivo deste trabalho foi avaliar a sensibilidade genotipica, por meio de funcoes preditas entre a diferenca do potencial rendimento de graos medio (kg [ha.sup.-1]), considerando todas as combinacoes possiveis entre os ambientes estudados. Ausencia de significancia para todos os genotipos testados de feijao preto indica um comportamento insensivel destes genotipos frente as variacoes do par de ambiente Chapeco versus Lages. Por outro lado, o ambiente de Ponte Serrada, independentemente do grupo (preto ou carioca) e do outro ambiente de cultivo, afetou intensamente todas as funcoes preditas, indicando que estes genotipos devem ser recomendados para cultivo em ambientes estratificados. Palavras-chave: variancia fenotipica, BLUP, sensibilidade, rendimento de graos de feijao. |
