不断拓宽大豆遗传基础,是保持大豆育种材料的遗传多样性和防止大豆改良计划中育成品种可能出现遗传脆弱性的重要途径。1989年我们对中国农科院品种资源所提供的一批国外大豆品种资源进行了初步研究,以寻找其在长江下游大豆育种计划中进行利用的可能性。 Continued to broaden the genetic basis of soybean is an important way to maintain the genetic diversity of soybean breeding materials and to prevent possible genetic vulnerability of bred varieties in the soybean improvement program. In 1989, we conducted a preliminary study of a group of foreign soybean resources provided by the Chinese Academy of Agricultural Sciences in search of their potential utilization in the Yangtze River breeding program.
