通过对不同品种的甘蓝型油菜在低海拔冬油菜区(陕西大荔试验点,东经109.93度,北纬34.80度,海拔368m)和高海拔春油菜区(甘肃张掖试验点,东经100.45度,北纬38.93度,海拔2 300m)两个不同生态环境条件下穿梭选育,平均含油量得到有效提高。将所试的62份油菜品种(系)根据含油量归为低、中、高和特高含油量4类。经选育后,相同品种(系)的含油量有较大提高;从2006-2011年大荔试验点和张掖试验点含油量平均变幅分别为4.9%和6.57%,最高品系含油量达到61.53%;同时对含油量高、性状好的材料,进行组合测配,已选育出我国第一个含油量超过50%的杂交油菜秦杂油4号。
The experiment was carried out on low rape winter rapeseed (test point in Dali of China, 109.93 degrees east longitude, 34.80 degrees east longitude and 368 meters long elevation) and spring rapeseed region (Zhangye pilot station in Gansu province, longitude 100.45 degrees east longitude and 38.93 degrees north latitude Degree of elevation 2 300m) under two different ecological conditions shuttle breeding, the average oil content has been effectively improved. The tested 62 rape varieties (lines) were classified as low, medium, high and extra high oil content according to the oil content. After breeding, the oil content of the same varieties (lines) increased greatly. From 2006 to 2011, the average amplitude of oil content of Dali and Zhangye was 4.9% and 6.57% respectively, and the highest oil content reached 61.53 %; At the same time, the combination of high-oil content, good performance of the material, has been bred in China’s first oil content of more than 50% of hybrid rapeseed hybrid oil on the 4th.
