利用再合成的甘蓝型油菜（RS）基因型在商业育种计划中被限制在种内杂交种，所谓的半合成油菜籽，和回交后代的发展。以9个高芥酸油菜自交系和3个老春油菜品种为材料，对双低春油菜雄性不育系（MSL系统）进行授粉，测定不同材料的一般配合力。在多点田间试验中测试了单交种的产量表现，揭示了基于RS系的半合成油菜杂交种的高产潜力。讨论了这种再合成油菜籽形式在开发油菜杂交种中的用途及其在未来油料育种中的可能用途。(c)2005 Elsevier B.V.保留所有权利。
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. (c) 2005 Elsevier B.V. All rights reserved.
