Phenotypic variation of yield related traits in DH lines and hybrids of winter oilseed rape (Brassica napus L.)
Journal Title: Rośliny Oleiste - Oilseed Crops - Year 2016, Vol 37, Issue 1
Abstract
Oilseed rape (Brassica napus L.) breeding programs are mainly focused on obtaining varieties with high seed yield, which is associated with greater profitability of growing such varieties and increased consumption of vegetable oils. Improved productivity is obtained, among others, by F1 hybrids, in which the effect of heterosis occurs. The experiment was designed to investigate variation of yield related traits among 60 DH lines, 60 single cross hybrids (CMS×DH), 60 three-way cross hybrids (CMS/DH×Rfo), one CMS ogura line, and one Rfo line. Field experiment with a randomized blocks design included two growing seasons; this article presents data from the first year of observations. Traits evaluated in the field were: duration of flowering, 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. On the collected data the analysis of variance was performed and correlations between the studied traits were examined, considering the groups of genotypes. Analysis of variance showed statistically significant differences between groups for all eight traits. Flowering duration was the longest in the group of CMS×DH hybrids and the shortest in the Rfo plants. The CMS/DH×Rfo hybrids were characterized by the largest plant height. The lowest height had Rfo restoring line, which also had the largest number of branches and siliques per plant. This line achieves, however, the lowest values for traits such as length of siliques, number of seeds per silique and thousand seeds weight. The highest thousand seed weight was observed in the group of CMS×DH hybrids and in the CMS ogura line. The lowest oil content in seeds was noted in the group of DH lines, and the highest – in the CMS/DH×Rfo hybrids and CMS ogura line.
