为了创造大豆新种质,近几年采用γ射线、热中子等核辐射,以及甲烷磺酸乙酯(EMS) 、叠氮化钠( NaN3) 等化学诱变剂处理,经过多年的研究,选育出黑农41 大豆的蛋白质含量为45-23 % 、脂肪含量为18-8 % ;选育出903527 突变系为早熟、高蛋白(47-53 % ) 、高抗大豆病毒病及大豆灰斑病;同时筛选出一批高蛋白(49 % ～50 % ) 、高亚油酸(60 % 以上) 、低亚麻酸的优良突变系,为大豆基因库增添了新的优质资源,确定了有效的诱变技术。
In order to create a new soybean germplasm, nuclear radiation such as gamma rays and thermal neutrons, and chemical mutagens such as ethyl methane sulfonate (EMS) and sodium azide (NaN3) have been used in recent years. After years of research, The content of protein in Heinong 41 soybean was 45-23% and the content of fat was 18-8%. The 903527 mutant lines were bred early, high protein (47-53%), highly resistant to soybean virus disease and Soybean gray spot disease. A series of excellent mutant lines with high protein (49% ~ 50%), high linoleic acid (60%) and low linolenic acid were screened, which added new high quality resources to soybean gene bank, Effective mutagenesis.
