Abstract: [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.

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.
