Resumo: The objective of this work was to quantify the genetic diversity of elite genotypes of irrigated barley in the Brazilian savanna. Thirty elite barley genotypes from Embrapa Cerrados' collection were evaluated using 160 RAPD markers, 12 agronomic traits related to yield components, and 10 malting quality parameters. The genetic dissimilarity matrices based on molecular markers, quantitative traits, and malting quality characters were calculated and a cluster analysis was performed using the unweighted pair-group method with arithmetic mean (UPGMA) as grouping criterion. High genetic diversity among accessions were observed. The estimated genetic dissimilarities were weakly correlated, showing the complementarity of the different character groups. Selection indices and graphical dispersion analysis allowed the selection of promising genotypes and the indication of suitable crosses for maximizing the heterotic effects in breeding programs for irrigated barley in the Brazilian savanna.

Trinta genótipos‑elite de cevada, da coleção de trabalho da Embrapa Cerrados, foram avaliados com base em 160 marcadores moleculares RAPD, 12 características agronômicas relacionadas aos componentes de produção e 10 características de qualidade malteira. As matrizes de dissimilaridade genética foram calculadas com base nos marcadores moleculares e em caracteres quantitativos e qualitativos, e as análises de agrupamento foram realizadas com o método da média aritmética não ponderada (UPGMA) como critério de agrupamento. Observou-se elevada diversidade genética entre os acessos. As dissimilaridades genéticas estimadas estiveram fracamente correlacionadas entre si, o que evidenciou a complementaridade dos diferentes grupos de características. A utilização de índices de seleção e a análise de dispersão gráfica permitiram a seleção de genótipos promissores e a indicação de cruzamentos apropriados para maximizar os efeitos heteróticos no programa de melhoramento genético da cevada irrigada no Cerrado.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraEmbrapa e CNPqAmabile, Renato FernandoFaleiro, Fábio GelapeVieira, Eduardo AlanoPeixoto, José RicardoCapettini, FlávioRibeiro Júnior, Walter Quadros2013-10-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13925Pesquisa Agropecuaria Brasileira; v.48, n.7, jul. 2013; 748-756Pesquisa Agropecuária Brasileira; v.48, n.7, jul. 2013; 748-7561678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/13925/12249https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/13925/9371info:eu-repo/semantics/openAccess2013-10-31T18:42:04Zoai:ojs.seer.sct.embrapa.br:article/13925Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2013-10-31T18:42:04Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
