70年代以来,瑞典、苏联、波兰、瑞士、加拿大、美国、日本、南朝鲜、尼日利亚、澳大利亚和印度尼西亚等国纷纷开展了大豆抗冷种质的筛选、鉴定与利用研究。我国虽也进行了初步的研究,但获得抗冷种质资源极少,不能满足生产和育种的需要。本文通过对东北大豆资源的萌发期耐冷筛选,初步获得了一批冷种质资源,可为生产、遗传育种和植物生理生化研究或利用提供材料。
Since the 1970s, many countries such as Sweden, the Soviet Union, Poland, Switzerland, Canada, the United States, Japan, South Korea, Nigeria, Australia and Indonesia have carried out the screening, identification and utilization of soybean cold-resistant germplasm. Although our country has conducted a preliminary study, access to cold germplasm resources is very small, can not meet the needs of production and breeding. In this paper, a batch of cold germplasm resources were preliminarily obtained through the cold screening of the germination phase of soybean resources in Northeast China, which could provide materials for the research and utilization of production, genetic breeding and plant physiology and biochemistry.
