Resumo: Recently, a new race of soybean cyst nematode (SCN) (Heterodera glycines) was discovered, which breaks the resistance of cultivar Hartwig, resistant to all known races of SCN. This population was obtained from soybean plants collected in the Sorriso county, state of Mato Grosso, Brazil, and is characterized as race 4. To verify if this isolate was different from others classified as races 4 and 9, their genetic diversity was analyzed by using the RAPD technique. Nine populations of SCN were analyzed, and only four populations were able to parasitize soybean plants cultivar Hartwig. Based on this study, it was verified that the populations that break Hartwig resistance were different from the other populations. Based on cluster analysis, the populations were separated into three groups. Race 4 populations were placed in the first group, while the race 9 population was placed in the second group and those capable of breaking cultivar Hartwig's resistance were placed in group three. This work confirms that the SCN population found in Sorriso is different from other isolates classified as race 4, and was called race 4+.

Essa população foi coletada no Município de Sorriso, Estado do Mato Grosso, e foi caracterizada como raça 4. Para verificar a diversidade genética entre esta e outras populações pertencentes às raças 4 e 9, foi feita uma caracterização molecular pela técnica de marcadores moleculares RAPD. Foram utilizadas nove populações do NCS, das quais quatro apresentavam a capacidade de parasitar 'Hartwig'. Foi verificado que as populações capazes de parasitar 'Hartwig' foram bastante diferentes das demais. Por meio de análise de agrupamento, com base nas distâncias genéticas encontradas, foram obtidos três grupos: o primeiro, constituído por indivíduos classificados como raça 4, mas que não parasitam 'Hartwig'; o segundo, constituído por quatro populações capazes de parasitar 'Hartwig', e o terceiro, por apenas uma população, classificado como raça 9, e que também não parasita 'Hartwig'. Este estudo confirmou que a população de NCS, encontrada em Sorriso, é geneticamente distinta das demais populações da raça 4 encontradas e constitui uma nova raça, denominada 4+.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAbdelnoor, Ricardo VilelaDias, Waldir PereiraSilva, João Flávio VelosoMarin, Silvana Regina RockenbachKiihl, Romeu Afonso de Souza2001-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6128Pesquisa Agropecuaria Brasileira; v.36, n.2, fev. 2001; 331-337Pesquisa Agropecuária Brasileira; v.36, n.2, fev. 2001; 331-3371678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6128/3195info:eu-repo/semantics/openAccess2014-11-06T16:54:21Zoai:ojs.seer.sct.embrapa.br:article/6128Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-06T16:54:21Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
