Resumo: The objectives of this work were to characterize the genetic diversity of tomato accessions from the Vegetable Germplasm Bank of Universidade Federal de Viçosa (BGH-UFV) and to evaluate the relative importance of characters in determining this diversity. Seventy tomato accessions were evaluated in three experiments in a randomized block design with three replicates, using the Santa Clara and Débora Plus cultivars as controls. In the first experiment (January to July 2002), 30 accessions were evaluated; in the second (August to December 2002) and the third (January to July 2003) experiments, 20 accessions were evaluated. The divergence study was performed through the joint analysis of variance, the grouping of the averages by the Scott-Knott test, and the grouping of accessions by Tocher's method. The study of the relative importance of characters was done by the Singh method and by canonical variables. The variability for 16 characters was verified by the Scott-Knott test, and the accessions were separated in ten groups according to Tocher's method. There is great genetic diversity between tomato accessions of BGH-UFV, with high variation in morphologic, agronomic and quality characteristics.

Setenta acessos de tomateiro foram avaliados em três experimentos em blocos ao acaso, com três repetições, com as cultivares Santa Clara e Débora Plus como testemunhas. No primeiro experimento, de janeiro a julho de 2002, foram avaliados 30 acessos; no segundo, de agosto a dezembro de 2002, e no terceiro, de janeiro a julho de 2003, 20 acessos. No estudo de diversidade genética, foram realizadas análises de variância agrupada, agrupamento das médias pelo teste de Scott-Knott e agrupamento dos acessos pelo método de Tocher. Foi realizado, também, o estudo da importância relativa de caracteres pelo método de Singh e por variáveis canônicas. A variabilidade para 16 características foi verificada pelo teste de Scott-Knott, e os acessos foram separados em dez grupos pelo agrupamento de Tocher. Existe grande diversidade genética entre acessos de tomateiro do BGH-UFV, com ampla variação tanto para características morfológicas quanto para características agronômicas e de qualidade.    Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPq, FAPEMIGMarim, Bruno GarciaSilva, Derly José Henriques daCarneiro, Pedro Crescêncio SouzaMiranda, Glauco VieiraMattedi, André PugnalCaliman, Fabiano Ricardo Brunele2010-12-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/2168Pesquisa Agropecuaria Brasileira; v.44, n.10, out. 2009; 1283-1290Pesquisa Agropecuária Brasileira; v.44, n.10, out. 2009; 1283-12901678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/2168/5841https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/2168/1559info:eu-repo/semantics/openAccess2012-06-17T11:53:41Zoai:ojs.seer.sct.embrapa.br:article/2168Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:53:41Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
