Genetic progress in popcorn recurrent selection by a multivariate mixed-model approach

Abstract: Recurrent selection is a viable alternative for popcorn breeding. However, frequent verification of progress attained is required. The aim of this study was to estimate the genetic progress attained for popping expansion (PE) and grain yield (GY) after four cycles of recurrent selection and to compare this progress with the expected progress estimated at the end of each cycle while considering the genetic relationships between the progenies via univariate and multivariate mixed-model approaches. To estimate th… Show more

“…In this approach, the genetic and residual correlations between traits are used to estimate the genetic value. Therefore, the efficiency of the method may be related to the correlation between traits and heritability estimates (Ematné et al 2018).…”
