摘要: 番木瓜环斑病毒西瓜株系(PRSV-W)、小西葫芦黄花叶病毒(ZYMV)、西瓜花叶病毒(WMV)和黑星病(Cladosporiumcucumerinum)是为害黄瓜的主要病害。以欧洲八号×秋棚为亲本构建的RIL群体为材料,以病情指数为指标,对群体和亲本进行了小西葫芦黄化花叶病毒(ZYMV)、番木瓜环斑病毒西瓜株系(PRSV-W)、西瓜花叶病毒(WMV)株系和黑星病的抗病性鉴定。结果表明:上述抗性基因的病情指数在黄瓜RIL群体呈双峰分布,表明对ZYMV,PRSV和WMV的抗性是受主基因控制的性状,但也存在微效基因的修饰作用。连锁分析表明,ZYMV,PRSV与WMV连锁,3个抗病基因的排列顺序和遗传距离是ZYMV-10cM-PRSV-22cM-WMV。抗黑星病基因与上述三种抗病毒基因不连锁。

Abstract: The watermelon strain of papaya ringspot virus (PRSV-W), zucchini yellow mosaic virus (ZYMV), watermelon mosaic virus (WMV) and scab(cladosporium cucumerinum) are major diseases that cause significant disease losses in cucumber. Based on a RIL population (No. 8 European × Qiupeng), disease evaluations are identified. The frequency distribution in cucumber RIL population for DI traits involving resistance to the PRSV-W, WMV, ZYMV and scab show two peaks. This indicate that resistance to these diseases are controlled by main gene, but some minor gene also have moderate effect. The linkage analysis results showed that ZYMV, PRSV-W and WMV are linked, the sequence is ZYMV-10cM-PRSV-22 cM-WMV.
