小麦赤霉病是长江中下游地区小麦的主要病害。应用抗病品种是防治赤霉病最经济有效的措施。但长期以来，抗赤育种进展缓慢，其重要原因之一就是抗赤性遗传机制复杂和缺乏抗性选择的可靠指标。分子生物学的飞速发展为遗传育种工作提供了新的遗传标记和研究方法。本研究利用RAPD
Wheat scab is the main disease of wheat in the middle and lower reaches of the Yangtze River. Application of resistant varieties is the most economical and effective measures to control scab. However, one of the important reasons for the slow progress of anti-red breeding has long been a reliable indicator of the complex genetic mechanism of resistance and the lack of resistance selection. The rapid development of molecular biology provides new genetic markers and research methods for genetic breeding. This study uses RAPD
