【摘要】 为掌握西藏油菜品种选育水平，围绕产业需求指明育种创新方向，更好地发挥品种登记制度作用，介绍了西藏甘蓝型油菜登记品种特性、品质及产量表现，并进行农艺性状和产量性状比较分析。研究表明：近年来甘蓝型油菜登记品种有藏油5号、京华165、藏油12号、大地95、藏油15号，品质明显改良，硫苷和芥酸明显降低，含油率有增高的趋势。在产量性状方面，角果密度、每果粒数和千粒质量总体呈增加趋势。针对西藏不同生态区域和产业发展需求，在品种选育创新方面，要加强短生育期、适宜机械化种植等多用途品种的选育，从而推动西藏油菜产业高质量发展。更多还原

【Abstract】 In order to grasp the breeding level of rapeseed varieties in our region, point out the direction of breeding innovation around the industrial demand, and better utilize the role of variety registration system, this paper introduces the characteristics, quality and yield performance of registered varieties of Brassica napus in our region, and makes a comparative analysis of agronomic traits and yield traits through unified cultivation.The study found that in recent years, the registered varieties of Brassica napus such as Zangyou 5, Jinghua 165, Zangyou 12, Dadi 95 and Zangyou 15 had significantly improved in quality with the significantly reduction in the glucosinolate and erucic acid, and a trend towards the increased oil content. In terms of yield traits, pod density, grain number per fruit and 1000-grain weight showed an overall increasing trend.In view of the needs of different ecological regions and industrial development in Xizang, in the direction of variety breeding and innovation, it is necessary to strengthen the breeding of multi-purpose varieties such as short growth period and suitable for mechanized planting, to promote the high-quality development of rapeseed industry in our region.更多还原
