【摘要】 向日葵白锈病和黑茎病是近年来外来入侵两种检疫性新病害,国内对种植的向日葵品种抗病性鉴定研究较少。在自然发病条件下,通过对2011年新疆伊犁河谷新源县向日葵种植产区的32个向日葵品种(油葵16个品种,食葵16个品种)发病程度的调查结果表明:向日葵品种间抗病性存在明显差异,向日葵两种外来入侵检疫性病害——向日葵黑茎病、白锈病的抗性调查结果,32个品种无一免疫品种。油葵品种对黑茎病的相对抗病性无免疫品种,有6.25%表现为高抗,68.75%表现为中抗,18.75%表现为中感,6.25%表现为高感;对白锈病的相对抗病性无免疫品种,37.5%表现为高抗,50%表现为中抗,6.25%表现为中感和高感。供试油葵品种中CK3-KWS303、TK555、TK601 3个品种向日葵黑茎病、白锈病的病情指数相对较低,抗病性强,产量高;CK3-KWS303、TK555G两个品种产量较高。食葵品种对黑茎病的相对抗病性无免疫和高抗品种,25%表现为中抗,50%表现为中感,25%表现为高感;对白锈病的相对抗病性无免疫品种,6.25%表现为高抗,62.5%表现为中抗,12.5%表现为中感,18.75%表现为高感。供试食葵品种中CK1-5009向日葵黑茎病、白锈病发病较轻,对黑茎病表现为中感,白锈病表现为中抗。更多还原

【Abstract】 Sunflower white rust and black stem disease is a recent invasive the 2 kind quarantine disease. Domestic to Plant Sunflower Varieties Research less Resistance Identification.Under natural field conditions,In 2012,through Xinjiang Yili Valley of Xinyuan County plant a sunflower areas of 32 varieties of sunflower(16 oil Sunflower Variety,varieties of edible sunflower 16 varieties ) incidence degree investigation results show that:Sunflower varietal resistance exist obvious differences,sunflower 2 of kind alien quarantine diseaseblack stem disease.,sunflower white rust,resistance survey results,32 varieties without immune varieties. Oil Sunflower Variety of black stem relative resistance without immune varieties,6.25%showed high resistance performance,68.75%performance for the medium resistance,18.75%showed moderate infected of white rust,6.25%of showed high sense of white rust;sunflower white rust relative resistance without immune varieties,37.5%showed high disease-resistant,50%against medium disease-resistant,The 6.25%showed moderate infected and showed high sense of white rust.Test for oil sunflower varieties CK3-KWS303,TK555, TK601 3 varieties of sunflower black stem disease,white rust disease index was relatively low,strong disease resistance,high yield CK3-KWS303,TK555 2 varieties of comparison high yield. Edible sunflower varieties to black relative resistance of immunity and high resistant varieties,25%performance for medium resistance,50%showed medium sense of black stem disease,25%showed high sense of black stem disease,sunflower white rust relative resistance without immune varieties,6.25%showed high resistance, 6.25%performance for the medium resistance,12.5%showed medium sense of white rust, 18.75%high sense of white rust.Test of edible sunflower varieties CK1 -5009 sunflower black stem disease, white rust lesser incidence,on black stem disease manifested as medium sense,white rust resistance performance of as medium resistance.更多还原
