| Abstract: | The utilisation of resynthesized Brassica napus (RS) genotypes in commercial breeding programmes is restricted to the development of intraspecific hybrids, so-called semi-synthetic rapeseed, and backcross progenies. In order to determine the general combining ability (GCA) of different rapeseed material, nine high-erucic acid RS lines and three old spring rapeseed cultivars were used as pollinators of male sterile double-low spring rapeseed lines (MSL-system). Yield performance of the single-cross hybrids was tested in a multi-location field trial that revealed a high yield potential of semi-synthetic rapeseed hybrids based on RS lines. The use of such resynthesized rapeseed forms in developing rapeseed hybrids and their possible use in future oilseed breeding is discussed. |
