【摘要】 以栽培大豆品系6296—3为受体、半野生大豆龙79—3433—1为供体,采用外源DNA导入的方法培育成功D89—9822.该品系具有高产、品质优良、抗病性强等特点,产量比受体增产44.9%,比标准品种增产10.5%.蛋白质含量7年(1989—1995)平均较受体增长近2个百分点,球蛋白总量较受体提高近10个百分点,并使其与大豆加工品质密切相关的11S球蛋白组分所占比例超过70%.1996年参加生产试验.外源DNA导入法在大豆育种上有缩短周期,减少远缘交配后的不育性和分离性,易于集中育种目标选择等优点.更多还原

【Abstract】 A new soybean strain D89-9822 was successfully breed out with the biotechnology of re-ceived exogenous DNA. The recipient is 6296-3 (G. max). The dondo is Long 79-3433-1 (G.soja). The new strain is high yeild. Its yield was 44. 9% higher than recipient. It’s proteincontent was increased nearly 2 percent more than the recipient. The total globin and 11s globinwere highly increased. Disease resistance was improved. Attending regional test of the Provincein 1996. This strain is an achievement obtained from combination of biotecnology and conventce-nal breeding, and is very prospective for using as releasing variety spread propects.更多还原
