摘　　要：通过小区对比与大田示范相结合的方法,将西藏目前生产上主要的6个甘蓝型油菜品种在山南河谷农区进行对比分析,考察各品种在生育期、农艺性状、产量和品质上的差异。结果表明:山油2号、山油4号、藏油5号、大地95和京华165在山南河谷农区具有较好的产量表现,适宜在山南河谷农区种植,且大地95作为引进优质油菜代表,对提升我区油菜品质有积极作用。年河18号作为早熟甘蓝型品种建议向更高海拔区开展小面积引种试验,并结合综合表现替代当地白菜型农家品种。By the combination of field demonstration and plot comparison experiment, the 6 Brassica napus varieties currently promoted in Tibet were compared and analyzed, and the differences of growth period, agronomic characteristics, yield and quality of each variety were investigated. The results showed that Shanyou No. 2, Shanyou No. 4, Zangyou No. 5, Dadi 95 and Jinghua 165 had good yield performance in agricultural areas of Shannan River valley and were suitable to plant in agricultural areas of Shannan River valley.Dadi 95 was a representative of "double-low" rape introduced from the other areas, which had a positive effect on improvement of the rapeseed quality in Shannan area. As an early-maturing variety, Nianhe 18 was recommended to be introduced to higher altitude areas for plot experiment, and its comprehensive performance was evaluated to replace local Brassica rapa varieties.
