我国向日葵育种研究工作开展较晚,种质资源较贫乏,尤其是抗性材料更少。据报道,欧美一些国家向日葵抗性育种发展较快。美国、南斯拉夫、法国等国的多数杂交种都抗霜霉病。目前国外还找到了锈病、褐斑病、灰霉病、白粉病、葵螟和列当等的抗源,有的还研究了抗性的遗传机制。有些国 China’s sunflower breeding research carried out later, the germplasm is poorer, especially less resistant materials. It is reported that sunflower resistance breeding has developed rapidly in some countries in Europe and the United States. Most hybrids in the United States, Yugoslavia and France are resistant to downy mildew. At present, foreign countries also found rust, brown spot, gray mold, powdery mildew, Kwai borer and column resistance and other sources, and some also studied the genetic mechanism of resistance.
