Abstract

The aim of the studies was to give a thorough analysis of the breeding procedure that had resulted in releasing a new cultivar of winter triticale at the Szelejewo Plant Breeding Company. The data obtained for grain yields in the series of experiments carried out in 1998–2002 were processed using SERGEN software. The following analyses were done: genotype × environment interaction, estimation and testing of the main effects of genotypes, and estimation of differences between breeding lines and standard cultivars. The most promising lines were selected based on the results of statistical analyses, and the outcome of a “virtual” selection was compared with the effects of selection made by breeders. It was revealed that many of the genotypes that had been eliminated by breeders should have been chosen to the next step of the breeding programme if based on the results of statistical analyses. Thus, it cannot be excluded that among the eliminated lines there were also the ones that might have been considered as new cultivars of winter triticale.
