人工诱变改良大豆品质的研究
INDUCED MUTATION FOR SOYBEAN QUALITY
【摘要】 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。
【Abstract】 Gamma rays of acute and cronic radiation,thermal neutrons as well as ethyl methane sulphonate(EMS),sodium azide(NaN\-3) of chemical mutagens were used to improve the quality of soybean seed.Some mutants of better quality were selected.“Heinong No.41” With proten and oil content of 45\^23% and 18\^80% respectively was tolerant to akali\|saline and had a higher yield potential;90\|3527 with earlier mature (110 days of growth period)and high protein content(47\^53%) had a resistance to soyean mosaic virus(SMV)and frogeye lief spot of soybean.The mutants with higher linoleic acid content(more than 60%)and lower linolenic acid content(less than 3\^5%)were developed.
