冬小麦品种资源的抗寒性鉴定是研究冬小麦品种资源的主要内容之一。评价不同品种的抗寒特性,对于充分利用种质资源具有十分重要的意义。为了了解新疆冬小麦地方品种的抗寒性,为抗寒育种提供依据,我们于1985和1986年在乌鲁木齐老满城试验站鉴定了149年新疆冬小麦地方品种的抗寒性,现将结果整理于下。 一、鉴定材料 供鉴定材料为新疆45个地、县的149个地方品种,种子由本院品种资源室提供。 Cold tolerance identification of winter wheat germplasm resources is one of the main contents of studying winter wheat germplasm resources. Evaluation of different varieties of cold resistance, for the full use of germplasm resources is of great significance. In order to understand the cold resistance of winter wheat landraces in Xinjiang and provide the basis for cold breeding, we identified the cold resistance of winter wheat cultivars in Xinjiang in 149 years in Lamangcheng Experimental Station of Urumqi in 1985 and 1986. The results are summarized as follows . First, the identification of materials for the identification of material in 45 prefectures and counties in Xinjiang, 149 local varieties, seeds from the Court species resources room.
