Resumo: | The objective of this work was to select the best sugarcane families to increase productivity (TCH) in T1 stage and monitor their performance in stages T2 and T3 of the sugarcane breeding program (PMGCA / UFPR / RIDESA). The experiments of stages T1 and T2 were performed at the experimental station of Paranavaí (PR) and T3 stage was installed in three locations in the northwestern of Paraná State. In the first phase (T1) 40 full-sib families from bi-parental crosses were evaluated and were correlated with selected families in the next stage of selection (T2), comparing the number of genotypes indicated by BLUPIS, and the number of clones that composed the T2 stage, by bulk selection. Data were analyzed by REML/BLUP methodology. In T1 stage, twenty and two (22) families were selected for T2 stage, and seven families were selected for T3 stage, being results of the crosses RB835486 x RB72454, SP70-1143 x RB855156, RB835054 x SP83-2847, SP80-3280 x RB835054, RB855156 x SP80-1816, SP80-3280 x RB855589, and SP80-3280 x RB835486. The BLUPIS selection procedure allowed the indication of a greater number of potential families and clones within these families. The genotypes with improved performance in subsequent phases were derived from families with positive genotypic values and yield above experimental average in the T1 stage. |

Os experimentos das fases T1 e T2 foram realizados na estação experimental de Paranavaí (PR) e a fase T3 foi instalada em três locais da região noroeste do estado do Paraná. Na primeira fase (T1) foram avaliadas 40 famílias de irmãos-completos oriundos de cruzamentos bi-parentais e foram correlacionados com as famílias selecionadas na etapa seguinte de seleção (T2), comparando o número de genótipos indicado pelo BLUPIS e o número de clones que compuseram o T2, via seleção massal. Os dados foram analisados via metodologia REML/BLUP. Vinte e duas (22) famílias foram selecionadas para a fase T2 e sete famílias foram selecionadas para a fase T3, sendo resultados dos cruzamentos RB835486 x RB72454; RB855156 x SP70-1143; RB835054 x SP83-2847; RB835054 x SP80-3280; SP80-1816 x RB855156; SP80-3280 x RB855589; e SP80-3280 x RB835486. A seleção via procedimento BLUPIS permitiu indicar maior número de famílias potenciais e clones dentro destas famílias. Os genótipos com melhor desempenho nas fases seguintes foram originados das famílias com valores genotípicos positivos e produtividade acima da média experimental em T1.UEL2014-02-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Experimentalapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1244910.5433/1679-0359.2014v35n1p101Semina: Ciências Agrárias; Vol. 35 No. 1 (2014); 101-112Semina: Ciências Agrárias; v. 35 n. 1 (2014); 101-1121679-03591676-546Xreponame:Semina.
