Resumo: The objectives of this work were to determine correlations between and within clonal generation, to estimate heritability for chips color, dry matter content and yield of potatoes, and their implications on selection. Two hundred and fifty clones of ten families were randomly chosen from a first clonal population, directed to chips processing, of the potato breeding program of Embrapa-Centro de Pesquisa Agropecuária de Clima Temperado. The clones were evaluated in second (G2), third (G3) and fourth (G4) generations during autumn and spring of 1999 and autumn of 2000, respectively, in Pelotas, RS. The coefficients of correlation between generations and the estimates of heritability within clonal generations were low for chips color, low to moderate for dry matter and incremental with generations for yield components. The coefficients of correlations between quality and yield component traits within each generation were low and, the majority, non significant. The estimates of heritability of joint G3 and G4 data analysis were moderate, moderately high and high, respectively, for chip color, dry matter content and yield.

Duzentos e cinqüenta clones de dez famílias foram escolhidos aleatoriamente de uma população de primeira geração clonal, destinada ao processamento de batatas chips, do programa de melhoramento genético de batata da Embrapa-Centro de Pesquisa Agropecuária de Clima Temperado. Os clones foram avaliados em segunda (G2), terceira (G3) e quarta (G4) gerações, respectivamente, no outono e primavera de 1999, e outono de 2000, em Pelotas, RS. Os coeficientes de correlação entre gerações e as estimativas de herdabilidade dentro das gerações clonais foram baixas em relação à cor de chips, baixas a moderadas quanto à matéria seca e incrementais com as gerações nos componentes de produção. Os coeficientes de correlação entre as características de qualidade e os componentes de produção dentro de cada geração foram baixos e, na maioria, não-significativos. As estimativas de herdabilidade dos dados conjuntos da G3 e G4 foram moderada, moderadamente alta e alta, respectivamente, em relação à cor de chips, teor de matéria seca e produção.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRodrigues, Andréa Felix SouzaPereira, Arione da Silva2003-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6613Pesquisa Agropecuaria Brasileira; v.38, n.5, maio 2003; 599-604Pesquisa Agropecuária Brasileira; v.38, n.5, maio 2003; 599-6041678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6613/3670info:eu-repo/semantics/openAccess2014-07-31T17:50:10Zoai:ojs.seer.sct.embrapa.br:article/6613Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-31T17:50:10Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
