摘要
为培育抗棒孢叶斑病的黄瓜种质,引进国内外黄瓜种质68份,通过成株期自然感染黄瓜棒孢叶斑病的方法,调查黄瓜种质的生长势、性型、叶色、瓜皮色及棒孢叶斑病病情指数,研究分析不同黄瓜种质对棒孢叶斑病的抗性及抗性分布频率。结果表明:68份黄瓜种质中,高抗种质10份,占14.71%;抗病种质占10.29%;中抗种质占11.76%;感病种质占29.41%;高感种质占33.82%。进一步分析黄瓜种质的抗性分布频率,欧洲温室型黄瓜较华南型和华北型黄瓜抗病,生长势越弱,越抗棒孢叶斑病,强雌黄瓜较雌雄同株黄瓜抗棒孢叶斑病,叶片深绿和绿的黄瓜较叶片黄绿的黄瓜抗棒孢叶斑病,瓜皮白绿的黄瓜较绿和浅绿的黄瓜更抗棒孢叶斑病。
In order to create cucumber germplasms that resist target leaf spot, this experiment researched andanalyzed resistance of 68 domestic and foreign cucumber germplasms to target leaf spot and the distribution ofresistance. Cucumbers were naturally infected by target leaf spot in adult stage. Growth vigor, sexual type, leafcolor, rind color and disease index of target leaf spot were investigated. The results showed that among the 68 germplasms, there were 10 high resistance germplasms which accounted for 14.71%, resistance germplasmswere 10.29%, moderate resistance germplasms were 11.76%, susceptible germplasms were 29.41%, and highsusceptible germplasms were 33.82%. The European greenhouse cucumbers had more resistance to target leafspot. The weaker the growth vigor, the more resistance the germplasms had to target leaf spot. Femalecucumbers had better resistance to target leaf spot. Cucumbers with dark green leaves were more resistant totarget leaf spot. Cucumbers with white green rinds were more resistant to target leaf spot.
