- Evaluation of common bean accesses with multi-category variables Amanda Nogueira de Albuquerque Marco Antônio Aparecido Barelli Leonarda Grillo Neves Vinícius Ribeiro Arantes Kleberson Luiz Miranda da Silva Agrociencias UPGMA Phaseolus vulgaris genetic divergence morphological description The morphologic traits of the common bean genotype (Phaseolus vulgaris L.) in Cáceres MT, Brazil, are evaluated to optimize genotypes for future improvement breeding cultures. Sixteen genotypes were evaluated through 33 morphological characters. The experiment was carried out in randomized blocks with four replicates at the Mato Grosso Company for Research and Extension (EMPAER) in Cáceres, Mato Grosso State. A dendrogram was produced by Unweighted Pair Group Method with Arithmetic Mean (UPGMA) and Plan projection. Results showed the occurrence of genetic variability among the genotypes and the dendrogram revealed the formation of two main groups, one comprised genotypes of the black group and the other comprised genotypes of the Cores and Carioca group, placed side by side. This fact may also be observed by a projection on a bi-dimension plane. The most divergent materials were LP 98-122 and Jalo Precoce, whereas the most similar genotypes were IPR Chopin and BRS Grafite, IPR Chopin and Graúna, IPR Chopin and LP 98- 122. Genotypes in the experiment have a possible genetic variability of being used in genetic breeding programs. 2011 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303026598024 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
