Peanut DNA was transfered into soybean through the passage of pollen tube after self-pollination. It. induced different variations of terminal type, plant height, maturing stage, node numbers On main stem, branch numbers, yield components and chemical qualities in receptor. Selecting on variant Plant, good lines with yield 11.9-25.1% higher and protein colltent 3.9-5.3% higher than receptor' S were gained.The results indicated that it is Possble to improve ecological character, yield conlponent and chemical quality by theltechnique of exogenous DNA tranSfer.
