利用花粉管通道在大豆自花授粉后将花生ＤＮＡ导入栽培大豆受体中，引起受体的结荚习性、株高、成熟期，主茎节数、分枝数、产量性状和化学品质等性状的广泛变异。对变异株进行选择，获得了产量比受体提高１１．９％～２５．１％，蛋白质含量提高３．９％～５．３％的变异株系。实验结果表明：利用外源ＤＮＡ导入技术进行生态性状、产量性状和化学品质方向的育种是可能的。 Pollen tube pathway was used to introduce peanut DNA into cultivated soybean receptor after self-pollination of soybean, which led to such factors as pod habit, plant height, maturity, number of main stem, branch number, yield traits and chemical quality The wide variation. Mutant strains were selected to obtain the yield of the receptor increased by 11.9% ~ 25.1%, the protein content increased by 3.9% to 5.3% of the mutant lines. The experimental results show that it is possible to introduce ecological traits, yield traits and chemical quality breeding using exogenous DNA introduction technology.
