Resumo: The objective of this work was to evaluate the genetic diversity of nine maize races (Zea mays ssp. mays) from Northwestern Mexico and one population of teosinte of the Balsas race (Zea mays ssp. parviglumis). A total of 649 alleles were identified, with an average of 20.9 alleles per locus using 31 microsatellite loci; 84.3% of them were polymorphic loci with a 0.49 expected heterozygosity. Graphic representation of principal coordinate analysis (PCoA) showed broad variation and population distribution. The highest probabilistic value obtained with the ΔK criterion confirmed the existence of five population groups clustered by the Bayesian model. This grouping coincided with the population distribution observed in the PCoA graph. Maize races examined retain broad genetic diversity among and within the evaluated populations.

Foram identificados 649 alelos, uma média de 20,9 alelos por locus, utilizando 31 loci microssatélites. Desses, 84,3% eram polimórficos e apresentaram heterozigosidade esperada de 0,49. A representação gráfica da análise de fatores principais (PCoA) mostrou ampla variação e distribuição populacional. O maior valor probabilístico obtido com o critério ΔK confirmou a existência dos cinco grupos populacionais agrupados com o modelo bayesiano. Esse agrupamento coincide com a distribuição populacional observada no gráfico PCoA. As raças de milho examinadas apresentam ampla diversidade genética entre e dentro das populações avaliadas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraIsrrael Vega-Álvarez, Colegio de PostgraduadosAmalio Santacruz-Varela, Colegio de PostgraduadosMario Rocandio-Rodríguez, Instituto de Ecologia Aplicada- Universidad Autonoma de TamaulipasLeobigildo Córdova-Téllez, Colegio de PostgraduadosHiginio LVega-Alvarez, IsrraelSantacruz-Varela, AmalioRocandio-Rodríguez, MarioCórdova-Téllez, LeobigildoLópez-Sánchez, HiginioMuñoz-Orozco, AbelHernández-Bautista, Aurelio2017-12-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/25083Pesquisa Agropecuaria Brasileira; v.52, n.11, nov. 2017; 1023-1032Pesquisa Agropecuária Brasileira; v.52, n.11, nov. 2017; 1023-10321678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/25083/14020Direitos autorais 2017 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2018-01-04T11:40:52Zoai:ojs.seer.sct.embrapa.br:article/25083Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2018-01-04T11:40:52Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
