Summary: The objective of this work was to evaluate and compare the genetic diversity of 29 barley genotypes, on the basis of molecular markers and quantitative agronomic traits, under irrigation in the Brazilian Cerrado. The randomly amplified polymorphic DNA (RAPD), inter sequence simple repeats (ISSR), and simple sequence repeat (SSR) molecular markers were used. The quantitative agronomic traits were evaluated in two irrigated environments in the Brazilian Cerrado, for the following parameters: estimated grain yield, grain size, thousand seed weight, plant height, lodging degree, and days to heading. Marker polymorphisms were 91, 51.46, and 85% for RAPD, ISSR, and SSR, respectively. The RAPD, ISSR, and SSR markers are complementary for the identification of genetic variability among barley genotypes. The low correlations between the distances estimated on the basis of molecular markers and the distances estimated on the basis of agronomic traits emphasize the importance of using complementary analyses of molecular markers for more complete studies on genetic variability. The agronomic traits of the genotypes are different in the two environments. The selected genotypes can compose the working collection of irrigated barley in the Brazilian Cerrado because of their wide genetic variability.

Foram utilizados os marcadores moleculares “randomly amplified polymorphic DNA” (RAPD), “inter simple sequence repeats” (ISSR) e “simple sequence repeat” (SSR). As características agronômicas quantitativas foram avaliadas em dois ambientes, sob irrigação no Cerrado, quanto aos seguintes parâmetros: rendimento estimado de grãos, tamanho do grão, peso de mil sementes, altura de plantas, grau de acamamento e dias para espigamento. Os polimorfismos dos marcadores foram 91, 51,46 e 85% para RAPD, ISSR e SSR, respectivamente. Os marcadores RAPD, ISSR e SSR são complementares quanto à identificação da variabilidade genética dos genótipos de cevada. As baixas correlações entre as distâncias calculadas com base nos marcadores moleculares e as distâncias calculadas com base nas características agronômicas enfatizam a importância da utilização de análises complementares de marcadores moleculares para estudos mais completos quanto à variabilidade genética. As características agronômicas dos genótipos são distintas nos dois ambientes. Os genótipos selecionados podem compor a coleção de trabalho de cevada irrigada no Cerrado, em razão de sua ampla variabilidade genética.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSayd, Ricardo MenesesAmabile, Renato FernandoFaleiro, Fábio GelapeBrige, Felipe Augusto AlvesMelo, João Victor Pinheiro2022-08-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/27111Pesquisa Agropecuaria Brasileira; V.57, Jan./Dec., 2022: Publicação contínua em volume anual; e02731Pesquisa Agropecuária Brasileira; V.57, Jan./Dec., 2022: Publicação contínua em volume anual; e027311678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/27111/15048Direitos autorais 2022 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2023-01-23T13:40:21Zoai:ojs.seer.sct.embrapa.br:article/27111Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2023-01-23T13:40:21Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
