西藏小麦品种和引进品种在拉萨种植的品质比较

Quality comparison between Tibetan wheat cultivars and introductive cultivars in Lasa

为了给西藏优质小麦生产的品种利用提供依据 ,1998～ 2 0 0 0年 ,用 7个西藏春小麦品种和 4个引进品种在拉萨进行了 3年春播试验 ;1998～ 2 0 0 1年 ,用 2个西藏冬小麦品种和 3个引进品种进行了 3年秋播试验。结果表明 ,西藏品种的蛋白质含量、湿面筋含量、沉降值明显低于引进品种。西藏品种属于弱筋小麦品种。西藏优质专用小麦生产中的品种利用途径是 :加强中筋小麦的生态育种 ;

In order to provide basis for utilization of cultivars in the production of Tibetan good quality wheat,7 Tibetan spring wheat cultivars and 4 introductive cultivars were employed for spring-sown experiments in Lasa from 1998 to 2000,while 2 Tibetan winter wheat cultivars and 3 introductive cultivars were tested for autumn-sown experiments from 1998 to 2001.The results showed that protein content,wet gluten content and sedimentation value for the Tibetan cultivars were significantly lower than those for introductive cultivars.Tibetan cultivars belong to weak gluten wheat.The ways of utilization of cultivars for Tibetan good quality and special wheat were as following:strengthening ecological breeding for the middle gluten wheat,and introducing inland strong gluten cultivars.
