Resumo: | This study aimed to quantify genetic variability among 46 accessions of papaya from ‘Solo’ and ‘Formosa’ groups using 19 morphoagronomic traits separately and simultaneously, and to evaluate the efficiency of simultaneous analysis. The experiment was conducted for three growing seasons (May and August 2007, and November 2008), in Linhares-ES, using a randomized block design with two replications and 20 plants in two rows per plot. Quantitative traits were analyzed by analysis of variance and then used to estimate the Mahalanobis distance, while for the qualitative traits it was used the coefficient of simple coincidence. The genetic distance for the joint analysis was estimated based on the algorithm of Gower. The matrices of distance were compared using the Mantel correlation with 1000 permutations. The clusters of accessions were performed by UPGMA. Although they have made the same number of groups (seven), both types of variables separately and jointly did not allow the formation of groups substantially similar to the group ‘Formosa’. On the other hand, the accessions of ‘Solo’ group were allocated practically in the group I for all distance used. The cluster formed by the data simultaneously provided greater disjunction of accessions, due to greater homogeneity within groups and heterogeneity among groups. |

O experimento foi conduzido em três épocas distintas (maio e agosto de 2007, e novembro de 2008), no município de Linhares-ES, utilizando-se delineamento em blocos casualizados, com duas repetições e 20 plantas por parcela em fileira dupla. As características quantitativas foram submetidas à análise de variância e posteriormente, utilizadas para estimar a distância de Mahalanobis, enquanto para os descritores qualitativos utilizou-se o coeficiente de coincidência simples. A análise conjunta das variáveis quantitativas e qualitativas foi estimada com base no algoritmo de Gower. As matrizes de distâncias foram comparadas usando a correlação de Mantel com 1000 permutações. Posteriormente, foi realizado o agrupamento dos acessos pelo método UPGMA. Embora tenha sido constituído número igual de grupos (sete), os dois tipos de variáveis separadamente ou em conjunto não possibilitaram a formação de agrupamentos consideravelmente semelhantes para o grupo Formosa. Ao contrário, os acessos do grupo heterótico Solo ficaram alocados praticamente no grupo I em relação a todos os métodos de distância. O agrupamento formado pelos dados em conjunto proporcionou maior disjunção dos genótipos, decorrente de maior homogeneidade dentro dos grupos e heterogeneidade entre os grupos.UEL2012-04-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/585910.5433/1679-0359.2012v33n1p131Semina: Ciências Agrárias; Vol. 33 No. 1 (2012); 131-142Semina: Ciências Agrárias; v. 33 n. 1 (2012); 131-1421679-03591676-546Xreponame:Semina.
