Abstract

Parental selection is one of the most crucial steps to improve genetic gain in any breeding program. The objective of the present work was to propose a mathematical model to estimate, from the selection information, the genetic value of parents and crosses with the processing of various variables in their progenies in sugarcane in Cuba. For this, information was used from the first three stages of selection (postures, clonal propagation 1 and 2) of the improvement program developed in the south-eastern region of Cuba, from 2000 to 2007. Likewise, the computer system was used SASEL, used in the genetic improvement of sugarcane, to program the proposed mathematical model. The model allowed estimating, in a multivariate way, the genetic value of the parents and crosses used in the genetic improvement program of sugarcane in Cuba. It was possible to establish, from the prediction of this value, the most outstanding parents and crosses in the analyzed period, which constitutes a useful tool to contribute to the improvement of the improvement program.
