Genotypic evaluation and selection of sugarcane clones in three environments in the state of Paraná.

Genotypic evaluation and selection of sugarcane clones in three environments in the state of Paraná.

The objective of this study was to estimate genetic parameters and predict genotypic values in sugarcane clones (series RB96) by the Reml/Blup methodology. The trial was installed in an unbalanced block design to evaluate the yield at three locations in the state of Paraná. The ranking of the clones regarding yield differed from one location to the other, due to the genotypic correlation of intermediate magnitude (0.62) across the locations. The two best clones presented a mean superiority of 28% (RB955466) and 19% (RB965518) over the general mean of the three locations. A comparison of the methods Mhprvg (harmonic mean of the relative performance of genetic values, according to Resende 2004) and Lin and Binns (1988) showed that both selected practically the same clones but the Mhprvg method presented the advantage of providing results in the measurement scale of the evaluated trait.
