Resumo: The aim of this study was to evaluate the performance of potato clonal families, and to estimate genetic variance, heritability and the expected response to selection of tuber yield and appearance traits in early generations. Twelve potato families were obtained from crosses between two groups of randomly-selected genotypes, including Eliza, C1730-7-94, and C-1742-8-95 in group 1; and Shepody, Asterix, Caesar, and White Lady in group 2. The crosses were made in factorial design (3 genotypes x4 genotypes), and each family consisted of 75 genotypes. Experiments were conducted in the fall of 2010, with a seedling generation under greenhouse conditions, and in the fall of 2011, with a clonal generation under field condition. High heritability estimates suggest that mild to moderate selection can be applied in the seedling generation to eye depth, eyebrow prominence, tuber curvature, flattening and shape uniformity. The C1742-8-95/White Lady stood out as a superior cross, as did all other crosses with White Lady, regarding tuber appearance and yield traits.

Foram avaliadas 12 famílias de batata obtidas de cruzamentos artificiais entre os dois grupos de genótipos escolhidos ao acaso, grupo 1: Eliza, C1730-7-94 e C1742-8-95; e grupo 2: Shepody, Asterix, White Lady e Caesar. Foram avaliados caracteres componentes de aparência de tubérculo e componentes de produção. Os cruzamentos foram realizados na forma de delineamento genético fatorial (3 genótipos x 4 genótipos), sendo cada família constituída de 75 clones. Os experimentos foram conduzidos nas safras de outono de 2010 em casa de vegetação e 2011 a campo. As altas estimativas de herdabilidade obtidas neste estudo sugerem que na geração de plântula pode-se aplicar seleção com intensidade de leve a moderada para profundidade de olho, proeminência de sobrancelha, curvatura de tubérculo, achatamento de tubérculo, aparência e uniformidade de formato de tubérculo. A família originária do cruzamento C1742-8-95/White Lady se destacou em relação às demais. No conjunto de caracteres de aparência e de produção de tubérculos destacaram-se as famílias em que um dos genitores foi a cultivar White Lady.UEL2016-10-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Experimentalapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1822610.5433/1679-0359.2016v37n5p2849Semina: Ciências Agrárias; Vol. 37 No. 5 (2016); 2849-2858Semina: Ciências Agrárias; v. 37 n. 5 (2016); 2849-28581679-03591676-546Xreponame:Semina.
