摘　　要：【目的】研究冬油菜在新疆绿洲生态区的适应性,筛选出适应于大面积种植的优良抗寒冬油菜品种,挖掘新疆冬油菜发展潜力。【方法】采用多点试验,对冬油菜在新疆不同地区的越冬率、生育期及主要农艺性状进行比较分析。【结果】白菜型冬油菜越冬率明显高于甘蓝型冬油菜,不同试点越冬率差异显著。经过主成分分析,白菜型冬油菜陇油9号在参试试点的综合得分排名均为第1;甘蓝型冬油菜DWKL-4排名均为第2。【结论】参试品种中白菜型冬油菜陇油9号、甘蓝型冬油菜DWKL-4生态适应性较强。新疆绿洲区冬季有稳定积雪覆盖的试点,冬油菜越冬率较高,主要农艺性状优良,生态适应性较强。[Objective] To further study the ecological adaptability of winter rapeseed in Xinjiang oasis area, select excellent winter rape variety for large area planting, and tap winter rapeseed development potential. [ Method] In this study, the winter wheat yield, growth period and main agronomic traits in different regions of Xinjiang were compared and analyzed. [ Result]The overwintering rate of Brassica rapa L. was significantly higher than that of Brassica napus L＇s The principal component analysis showed that the comprehensive scores of winter rapeseeds Longyou 9 in the test pilot areas ranked the first and DWKL - 4 ranked the second. [Conclusion]The tested varieties of Longyou 9 （Brassica rapa L. ） and DWKL -4 （Brassica napus L. ） have shown stronger ecological adaptability. It has been found that Xinjiang oasis has stable winter snow cover in winter and winter rape has higher over -wintering rate, excellent agronomic traits and strong ecological adaptability.
