1979~2003年,先后收集、整理、鉴定了野生大豆资源材料989份,组配各类型种间杂交组合676个。筛选出一批蛋白质含量480mg·g-1以上优异野生大豆种质49份;抗孢囊线虫3号生理小种的高抗种质8份;抗花叶病毒的野生大豆种质5份;多花荚、多分枝、抗逆性强等类型野生大豆种质9份;创造出蛋白质、脂肪双高661.6mg·g-1(龙品8807)品系1份和新种质类型8份。通过种间杂交,获得一批变异丰富、蛋白质含量高、百粒重在6~20g、抗逆性及丰产潜力大的优异中间材料,此外,选育推广了龙小粒豆1号特用新品种大豆,成为黑龙江省出口创汇的骨干品种。与此同时,利用花粉管通道技术,采用外源DNA导入技术,在中国首次选育出“黑生101”大豆新品种,拓宽了大豆种质遗传基础,丰富了大豆种质基因库。
From 1979 to 2003, 989 wild soybean resources materials were collected, sorted out and identified, and 676 combinations of various types of interspecific hybrids were assembled. A number of excellent wild soybean germplasms with a protein content of 480mg · g-1 were screened out, of which 49 were high-resistant germplasms of Cyclospora crassa 3, 5 were resistant to Mosaic virus 5, 9 varieties of wild soybean germplasm, such as flower pods, multi-branch and strong resistance, and 1 strain of 661.6 mg · g-1 (LongPu 8807) with double height of protein and fat and 8 new germplasm types. Through interspecific hybridization, a batch of excellent intermediate materials with abundant variation, high protein content, 100-600g weight, high resistance to stress and high yield potential were obtained. In addition, selection and popularization of Long Xia Zhidou No.1 special new variety Soybeans, become the backbone of export varieties in Heilongjiang Province. At the same time, using the pollen tube channel technology and using exogenous DNA introduction technology, the new “Heisheng 101” new soybean variety was bred in China for the first time, which broadened the genetic basis of soybean germplasm and enriched the gene bank of soybean germplasm.
