新疆冬季寒冷,降雪少、积雪薄的年份,不少地区常发生冬麦大面积冻害死亡。培育既抗寒又丰产的优良品种,是新疆小麦育种的头等重要任务。而鉴定小麦的抗寒力,则是小麦抗寒育种的必不可少的工作。在田间自然条件下直接鉴定小麦抗寒力的方法,其结果固然较可靠,但需时太长,又受不能重复再现的复杂的气候条件的影响,短时期内难以得出可靠的结果。因此,寻找快速而可靠的鉴定方法,是小麦抗寒育种急待解决的问题。近几年来,国内应用电导法鉴定小粒咖啡、玉米和苹果的抗寒力,已获成 Xinjiang winter cold, snow less, thin snow years, winter wheat often occur in many areas freeze-fatal deaths. Cultivating good varieties both hardy and high yielding is the top priority of wheat breeding in Xinjiang. The identification of wheat cold hardiness, it is an essential work of wheat breeding. The method of directly identifying the cold hardiness of wheat under natural conditions in the field is more reliable, but it takes a long time and is affected by complicated climatic conditions that can not be reproduced repeatedly. Therefore, it is difficult to draw reliable results in a short period of time. Therefore, looking for a fast and reliable identification method is an urgent problem for wheat breeding in cold breeding. In recent years, the domestic application of conductivity method identification of small grains of coffee, corn and apple cold resistance, has been
