摘要 本文论证了小麦抗BYDV育种的重要性,阐明了自50年代发现BYDV以后,科学家们首先将抗BYDV基因由小麦近缘种导入普通小麦,育成双二倍体,再作为中间材料培育成异附加系和异代换系,进而利用Ph突变体、组织培养、分子原位杂交等途径,育成易位系材料,最终应用于抗病育种的过程;明确了不同偃麦草与不同小麦杂交,导入的抗BYDV基因位点不同,从而扩大了抗源的多样性,同时也引起了遗传规律的差异;提出了现阶段抗病育种中存在的问题. Angle that the original is developed through the scientific knowledge. Demonstrate the importance that the resisted BYDV of wheat breeding. Clarify to discover the BYDV since the 1950,over a long period of time unremitting after scientists effort,first of all transfer the BYDV - resistance gene from the close fringe variety of wheat to common wheat, and breed amphidiploid, and go on breeding to hetero-addition line and hetero-substisution line. Second to breed translocation line by Ph's abrupt gene or tissue culture or in situ hybridization and so on. Finally use to the disease-resistant breeding. Cleared the variety of resisted source and the difference of genetic regularity because the crossing of different avena sativa and wheat caused the difference of BYDV-resistance-gene site. Pointed out the great accomplishment that resisted BYDV bred. Proposed the problem and direction in the disease-resistant breeding of wheat.
