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. |

The objectives of this study were to implement a Bayesian framework for mixed models analysis in crop species breeding and to exploit alternatives for informative prior elicitation. Bayesian inference for genetic evaluation in annual crop breeding was illustrated with the first two half-sib selection cycles in a popcorn population. The Bayesian framework was based on the Just Another Gibbs Sampler software and the R2jags package. For the first cycle, a non-informative prior for the inverse of the variance components and an informative prior based on meta-analysis were used. For the second cycle, a noninformative prior and an informative prior defined as the posterior from the non-informative and informative analyses of the first cycle were used. Regarding the first cycle, the use of an informative prior from the meta-analysis provided clearly distinct results relative to the analysis with a non-informative prior only for the grain yield. Regarding the second cycle, the results for the expansion volume and grain yield showed differences among the three analyses. The differences between the non-informative and informative prior analyses were restricted to variance components and heritability. The correlations between the predicted breeding values from these analyses were almost perfect. |
