43个丝瓜种质资源枯萎病抗性的鉴定与评价

    Identification and Evaluation of the Resistance of 43 Luffa Cylindrica Germplasm Resources to Fusarium Wilt

    • 摘要: 为了选育出抗病性强的丝瓜新品种,课题组从国内外收集了43个丝瓜种质资源,采用室内人工接菌的方法对其进行枯萎病抗性鉴定与评价,结果表明:春秋⊕21/白籽、2012-2-1-⊕5选、2012-2-4-⊕9-5、七美-⊕10、2012-2-1-⊕5选和2012-2-4-⊕9-5等6个丝瓜种质资源对枯萎病表现为高抗,三叶香嫩⊕20、翠霜-⊕19-2.5.6、绿优-⊕13/深绿等21个丝瓜种质资源对枯萎病表现为抗病,台湾-⊕8、名家短丝瓜⊕4、2012-2-⊕3选等12个丝瓜种质资源对枯萎病表现为中抗,日本早杂王⊕11、2012-2-⊕1-2.3、09-1-⊕1等4个丝瓜种质资源对枯萎病表现为感病。综合以上分析表明43个丝瓜种质资源中有27个种质资源对枯萎病表现为抗级以上,占总数的62.8%。

       

      Abstract: In order to breed the new varieties of Luffa cylindrica with strong disease resistance, 43 germplasm resources of Luffa cylindrica were collected from home and abroad by the research team, and the method of indoor artificial inoculation was used to identify and evaluate their resistance to fusarium wilt. The results showed that: the 6 germplasm resources of Luffa cylindrica including Chunqiu ⊕21/ baizi, 2012-2-1-⊕5 xuan, 2012-2-4-⊕9-5, Qimei-⊕10, 2012-2-1-⊕5 xuan, and 2012-2-4-⊕9-5 showed high resistance to fusarium wilt; the 21 germplasm resources of Luffa cylindrica, such as Sanyexiangnen ⊕20, Cuishuang -⊕19-2.5.6, Lvyou -⊕13/ shenlv, etc., showed resistance to fusarium wilt; the 12 germplasm resources of Luffa cylindrica, such as Taiwan -⊕8, Mingjiaduansigua ⊕4, and 2012-2-⊕3 xuan, etc., showed moderate resistance to fusarium wilt; and the 4 germplasm resources of Luffa cylindrica, such as Japan Zaozawang⊕11, 2012-2-⊕1-2.3, and 09-1-⊕1, etc., were susceptible to fusarium wilt. Based on the above analysis, 27 of the 43 germplasm resources of Luffa cylindrica showed higher resistance to fusarium wilt, accounting for 62.8% of the total.
