一、育种背景: 在世界范围内广泛开展着,将小麦近缘异种属植物高度抗病性遗传基因导入栽培小麦品种的育种研究。近年来,特别是由于染色体遗传工程技术的产生,使这项研究取得了卓越的成效。 在我国小麦育种领域中,也把抗叶锈病作为重要育种目标。1950年以来,在东北农业试验场对多数锈病生理小种(Race)(以下简称生理小种)进行相应的防治措施研究 First, the breeding background: Widely carried out in the world, the wheat heterologous genetically highly resistant wheat genetically introduced wheat cultivars breeding research. In recent years, this study has achieved remarkable results, especially because of the genetic engineering of chromosomes. In the field of wheat breeding in our country, leaf rust resistance is also an important breeding target. Since 1950, most of the rust race (hereinafter referred to as race) have been studied in Northeast Agricultural Experimental Station
