Blupis procedure and individual selection in sugarcane

The aim of this work was to compare the selection by simulated individual BLUP procedure (BLUPIS) versus individual selection in full-sib sugarcane families. Eighty families originated from bi crosses of RB03 series were used. The experiment was carried out in an experimental area in São Tomé County, Paraná State. The experimental design was in incomplete blocks, with five replications per family. For selection, the variable soluble solids per hectare (TSH) was used. For indication of the number of potential clones to be selected, the model 35 of the software Selegen REML/BLUP by BLUPIS procedure was used. The results of BLUPIS were correlated with the number of selected clones by individual selection. The results showed that clone selection by BLUPIS procedure can indicate higher number of promising clones for quantitative trait inside families with high genotypic effects.
