摘要
本文介绍了中国杂交油菜的研究历史及目前的进展情况。1990年中国的杂交油菜种植面积已达40多万公顷。4个杂交组合已通过省区域试验和品种审定。目前参加全国区域试验的杂交组合有18个。同时还分别介绍了中国在选育天然杂种、自交不亲和系杂种、化学杀雄杂种、核不育杂种、细胞质雄性不育杂种以及应用基础研究的情况。对当前杂交油菜的研究重点也进行了讨论。
The history ant advance of the studies on hybrid repeseed in China were presented in this paper.The planting area of rapeseed hybrids is over 0.4 million hectares this year(l990)in China.Four hybrids have passed the regionl test and cultivar examination in provinces.Now, eighteen rapeseed hybrids of B. napus are taking part in the regional test in provinces.
