西藏在油菜生产中，由于农民一直沿用本地多年留用的油菜品种，品种退化严重，产量低、品质差，油菜品种问题成为制约全区油菜发展的颈瓶。随着“双低”优质油菜品种的问世，油菜的产量和品质都有了大幅提高。本文通过从长江中上游及青海地区引种16份油菜新品种及本地5份品种(系)在西藏进行适应性种植研究。结果表明：从长江中上游和青海引进的油菜新品种在西藏中低海拔下种植均能完全成熟，经济性状和产量性状表现良好。特早熟品种2137和青杂4号在海拔4000m 的地区种植能够成熟，从此打破西藏高海拔地区无甘蓝型油菜种植的现状。

Rapeseed varieties was the neck bottles to rapeseed development of rapeseed pro-duction in Tibet region,because local farmers has used retained rape varieties for many years, species degradation was serious,low yields and poor quality.With the “double low”quality rape varieties available,the yield and quality of rapeseed had greatly improved.The study used the in-troduction of 1 6 new varieties from the Yangtze River and Qinghai areas and 5 local cultivars (lines)to plant adaptation research in Tibet.The results showed that introduce new varieties of rapeseed from the Yangtze River and Qinghai can fully mature at the middle and low altitude cul-tivation in Tibet,and economic traits and yield traits showed better.Special early-maturing va-rieties 2137 and qingza4 can be mature at an altitude of 4000m planted areas,which breaking the current situation at high altitudes in Tibet without Brassica cultivation.
