Genitores potenciais para hibridações identificados por divergência genética em feijão carioca

Abstract: RESUMONoventa genótipos de feijão carioca (Phaseolus vulgaris L.) foram avaliados, em dois anos agrícolas, em Santa Maria, RS, a fim de definir quais características agromorfológicas constituem-se como melhores descritores, realizar agrupamento em função de dissimilaridade genética e de definir quais combinações híbridas mais promissoras serão obtidas para o desenvolvimento de populações segregantes. Dos 20 caracteres agromorfológicos avaliados, apenas nove (ferrugem nos legumes, acamamento, nota geral, cor do… Show more

“…This fact indicated that the Tocher method was efficient in distinguishing cultivars from the different gene pools. The use of the genetic dissimilarity measure as a predictable hybrid value at the beginning of breeding programs, where there are a huge number of genotypes, is a very useful tool, because the parents for hybridization, instead of randomized, could be chosen by a genetic divergence study restricting crossings to only more promising combinations with economy in time and work (MALUF;COIMBRA et al, 1999;MACHADO et al, 2002;RIBEIRO;STORCK, 2003).…”

“…In agreement with Johnson e Wickern (1988) recommended the use of a set of genotypic and phenotypic traits to obtain information on genetic dissimilarity the use of multivariate statistics, which include canonic variables, principal component analysis and the cluster methods by Tocher and Single Linkage (CRUZ;REGAZZI, 1994). These have been widely used to characterize the common bean (BEEBE et al, 2000;BEEBE et al, 2001;ISLAM et al, 2002;RIBEIRO;STORCK, 2003;TEIXEIRA et al, 2004;CHIORATO et al, 2005;DURÁN et al, 2005;MIRANDA-LORIGADOS et al, 2006).…”

“…A panela é mantida em fogo médio e à medida que ocorre o cozimento, a haste cai e perfura o grão. O tempo médio de queda das 13 primeiras hastes foi considerado como tempo médio de cozimento de cada amostra (RIBEIRO et al, 2007).…”

“…A cor do tegumento dos grãos foi determinada com o auxílio de um colorímetro, por meio da leitura de luminosidade ("L"), que avalia a claridade da cor da amostra com variação de 0 a 100, ou seja, quanto maior o valor de "L", mais clara é a coloração do tegumento STORCK, 2003;RIBEIRO et al, 2008).…”
