Abstract

During the qualitative breeding of rapeseed (Brassica napus L.), the most important stage of obtaining heterotic hybrids, characterized by high yield and good qualitative features, is the selection of diversified parental lines with a large genetic distance. The aim of this study was to assess the variability of selected yielding traits in the population of doubled haploid lines (DH) and two populations of hybrids, produced using the CMS ogura line. Phenotypic observations included analysis of: flowering duration, plant height, number of branches per plant, number of siliques per plant, silique length, number of seeds per silique, thousand seed weight, and oil content in seeds. For the above parameters, the analysis of variance and correlation analysis were performed, considering the groups of genotypes.
