由于河套灌区连年大面积种植向日葵,导致菌核病和黄萎病发病率日益严重,选择适宜的抗病品种是防治病害的最重要措施。收集引进了适于河套灌区的10个食用向日葵杂交种进行种植,鉴定其在当地条件下的抗病性、熟性、形态特征、丰产性等。研究结果表明,所选的10个品种对菌核病的抗性都不高或易感,开花末期黄萎病的发病率大多在20%以上,试验所选品种黄萎病病情指数大多在1~2级,即中抗以上。DRZ1027、DRZ1028和DRZ1025产量较高,生物性状、经济性状及商品性的综合性状较好,后期菌核病发病率相对较低,是相对较好的品种。
由于河套灌區連年大麵積種植嚮日葵,導緻菌覈病和黃萎病髮病率日益嚴重,選擇適宜的抗病品種是防治病害的最重要措施。收集引進瞭適于河套灌區的10箇食用嚮日葵雜交種進行種植,鑒定其在噹地條件下的抗病性、熟性、形態特徵、豐產性等。研究結果錶明,所選的10箇品種對菌覈病的抗性都不高或易感,開花末期黃萎病的髮病率大多在20%以上,試驗所選品種黃萎病病情指數大多在1~2級,即中抗以上。DRZ1027、DRZ1028和DRZ1025產量較高,生物性狀、經濟性狀及商品性的綜閤性狀較好,後期菌覈病髮病率相對較低,是相對較好的品種。

It has a large-scale cultivation of sunflower in Hetao irrigation district which lead to a serious disease problem during planting process.Therefore,10 suitable sunflowers cultivars collected and introduced for planting and experiment in Hetao irrigation district.The purpose of experiment were identified the disease resistance,mature,morphological characteristics and yield.The results showed that 10 sunflowers cultivars had weak resistance and susceptible to Sunflower sclerotinia rot.The incidence of Verticillium Wilt was more than 20% at the end of flowering stage;furthermore,the disease index of selected varieties'Verticillium Wilt was between 1 -2 levels which showed the medium disease resistance.In addition, through experimental observation and data analysis,DRZ1027、DRZ1028 and DRZ1025 were relatively better than other cultivars in Hetao irrigation district,which showed high yield, better synthetic character in biological traits,economy traits and commodity traits,and lower incidence of Sunflower sclerotinia rot at the end stage.
