摘　　要：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。To improve the oil content of rapeseed,parent materials were used in breeding program shuttled from two sites at high and low altitudes during 2006 to 2011.One site was Dali in Shaanxi Province(E109.93,N34.80) at altitude of 368m.The other was Zhangye in Gansu Province(E100.45,N38.93) at altitude of 2 300m.The 62 parent varieties were divided into 4 groups of low,middle,high and extra-high oil content respectively.Ecological shuttle breeding effects showed that oil content of the same variety was improved greatly from 2006 to 2011.The average increase of oil content were 4.9% and 6.57% at Dali and Zhangye respectively.And the highest oil content reached 61.53% at Zhangye.Combining with elite agronomic traits breeding,high oil content(more than 50%) cultivar Qinzayou 4 was released by this ecological shuttle breeding method.
