野生大豆是栽培大豆近缘野生种,具有多抗、广适应性和繁殖系数高等优点。前人对野生大豆的抗旱性作了大量的研究、鉴定,发现野生大豆具有很强的耐旱能力。山西晋南地区常年都受到较高温度的影响,该地区的野生大豆具有一定的耐旱潜力。本实验对采集的山西省晋南地区野生大豆进行抗旱性鉴定,从中筛选出耐旱性较好的种质资源。 Wild soybean is the cultivation of wild relatives of soybean, with multi-resistance, wide adaptability and breeding coefficient advantages. Previous studies on the drought resistance of wild soybean made a lot of research, identification and found that wild soybean has a strong drought tolerance. Shanxi Jinnan perennial affected by higher temperatures, the region’s wild soybean has some drought potential. In this experiment, the drought resistance of wild soybean collected in Jinnan area of ​​Shanxi Province was identified, and the germplasm resources with better drought tolerance were screened out.
