Resumo: The aim of this study was to evaluate the reaction to hydric deficit of five bean genotypes of the black commercial group and five bean genotypes of the Carioca commercial group. Two experiments had been carried out in Londrina (PR) in 2002/2003 wet season. The hydric deficit was obtained during twenty days in the beginning of blooming phase. Mobile shelters constructed in iron had been used and covered with transparent roofing tiles to prevent the rain. During the period of hydric deficit, the soil humidity was determined in both treatments. In the phase of physiological maturation 10 plants of each subparcel were evaluated for number of knot, plant height, number of pods per plant, number of seeds per pod, 100 seed weight, plant yield and total yield. The estimates of the coefficients of genetic variation, coefficient of genotypic determination and B index indicated high genetic variability between the genotypes. The estimates of the coefficients of phenotypic correlation showed the presence of correlated characters indicating the possibility of doing simultaneous election between them. Based on the index of yield reduction and on the total yield of grains without hydric stress (kg /ha) genotype LP 99-85 of the black group and genotype LP 99-79 of the Carioca group were identified as tolerant to hydric deficit. The line LP99-79 has been registered for cultivation in the SNRC / MAP with the designation of IPR Siriri.

Foram estabelecidos em Londrina (PR), na safra das águas 2002/2003, dois experimentos independentes, um para cada grupo. O déficit hídrico foi imposto durante vinte dias na fase de início de florescimento, por meio de abrigos móveis de ferro, cobertos com telhas transparentes, para proteger da chuva. Durante o período de déficit hídrico, foi determinada a umidade do solo em ambos os tratamentos (com e sem déficit). No estádio de maturação fisiológica, foram amostradas, ao acaso, 10 plantas de cada subparcela, avaliando-se número de nós, altura da planta, número de vagens por planta, número de sementes por vagem, peso médio de 100 sementes, rendimento por planta e rendimento total. As estimativas dos coeficientes de variação genética, coeficiente de determinação genotípica e índice B indicaram alta variabilidade genética entre os genótipos. As estimativas dos coeficientes de correlação fenotípica revelaram a presença de caracteres correlacionados, indicando a possibilidade de se efetuar a seleção simultânea entre eles. Com base no índice de redução de produtividade e no rendimento total de grãos sem estresse (kg/ha), a linhagem LP 99-85 do grupo preto e a linhagem LP 99-79 do grupo carioca destacaram–se como as mais tolerantes ao déficit hídrico. A linhagem LP99-79 esta sendo registrada para cultivo no SNRC/ MAPA com a denominação de IPR Siriri.UEL2008-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/284810.5433/1679-0359.2008v29n1p1Semina: Ciências Agrárias; Vol. 29 No. 1 (2008); 1-14Semina: Ciências Agrárias; v. 29 n. 1 (2008); 1-141679-03591676-546Xreponame:Semina.
