花生DNA导入大豆育种效果的研究

A STUDY ON BREEDING EFFECT OF TRANSFERRING PEANUT DNA INTO SOYBEAN

摘要:

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。

Abstract:

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.
