Summary: The selection success in a breeding program depends on the existence of genetic variability. The objective of this work was to evaluate the level of genetic divergence among 24 common bean genotypes, being 22 F5 populations of the Common Beans Genetic Breeding Program of Epagri/Cepaf. Treatments were arranged in complete randomized blocks with four replications. The genetic divergence of eight agronomical important traits was estimated by the generalized distance of Mahalanobis. The genotypes were grouped by the method of Tocher and next neighbor. Populations CHP 97-05 and CHP 97-08- 21 were identified as the most promising. They will be further evaluated to obtain new lines. These two populations can also be crossed with populations identified as divergent and complementary in agronomic traits.

O objetivo deste trabalho foi avaliar o nível de divergência genética existente entre 24 genótipos de feijão, sendo 22 populações F5 do Programa de Melhoramento Genético de Feijão da Epagri/Cepaf. O experimento foi conduzido no delineamento de blocos casualizados, com quatro repetições. A divergência genética entre oito caracteres de importância agronômica foi estimada pela distância generalizada de Mahalanobis e os genótipos foram agrupados pelo método de Tocher e vizinho mais próximo. Identificaram-se como mais promissoras as populações CHP 97-05 e CHP 97-08-21. Estas populações devem ser conduzidas para a extração de novas linhagens, bem como poderão ser utilizadas em cruzamentos com outras populações identificadas como divergentes e complementares em caracteres agronômicos.Universidade do Estado de Santa Catarina2008-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/5329Revista de Ciências Agroveterinárias; Vol. 7 No. 1 (2008); 9-15Revista de Ciências Agroveterinárias; v. 7 n. 1 (2008); 9-152238-1171reponame:Revista de Ciências Agroveterinárias (Online)instname:Universidade do Estado de Santa Catarina (UDESC)instacron:UDESCporhttps://periodicos.udesc.br/index.php/agroveterinaria/article/view/5329/3535Elias, Haroldo TavaresBackes, Rogério LuizVogt, Gilcimar AdrianoPacassa, Luiz FernandoValentini, Giseliinfo:eu-repo/semantics/openAccess2022-07-01T14:54:01Zoai::article/5329Revistahttps://periodicos.udesc.br/index.php/agroveterinaria/PUBhttps://periodicos.udesc.br/index.php/agroveterinaria/oairca.cav@udesc.br | portal.periodicos@udesc.brhttps://doi.org/10.5965/223811712238-11711676-9732opendoar:2022-07-01T14:54:01Revista de Ciências Agroveterinárias (Online) - Universidade do Estado de Santa Catarina (UDESC)false
