- Abstract
The success of a breeding program among other factors is in achieving promising progenies. The objective of this study was to evaluate via REML/BLUP variance components and genotypic values for selection of promising wheat genotypes in crosses. The work was conducted in Boa Vista Missões - RS, the harvest 2011. The experimental design was a randomized complete block design with three replications. The wheat cultivars were used; BRS Guamirim, Coodetec 114, Abalone, Quartz, BRS 327 and Fundacep Horizonte. There evaluated: size cob, grain weight per spike, thousand grain weight, hectoliter weight and grain yield. Data were subjected to analysis via mixed models (REML/BLUP). The REML/BLUP estimates discriminated variance components and also the ordering of genotypic predictions of cultivars, these fundamental parameters for the plant breeder in targeting intersections. The Coodetec 114 and BRS 327 cultivars have higher grain yield, hectoliter weight and thousand grain weight when parameter considered is the overall average of all cultivars. These cultivars show potential to integrate blocks of crosses in obtaining populations with transgressive individuals.
