摘要
采用单一接种法和复合接种法对从国内外搜集的126份甜瓜种质资源进行苗期枯萎病和白粉病抗性鉴定。结果表明:单一接种条件下,枯萎病抗性评价结果为高抗种质7份,抗病种质42份,中抗种质61份,感病种质15份,高感种质1份;白粉病抗性评价结果为高抗种质9份,抗病种质42份,中抗种质72份,感病种质3份。复合接种条件下,筛选出甜瓜双抗种质1份,种质名称为PI164331,引自印度。通过两种接种方法相关性分析可知,复合接种鉴定结果与单一接种鉴定结果呈显著性正相关。
The resistances to Fusarium oxysporum f.sp.melonis racel and Sphaerotheca fuliginea race 1 of126 melon germplasm resources from China and abroad were identified by single and composite inoculations with spore suspension in seedling stage,respectively.The result indicated that under single inoculation condition,7were highly resistant to Fusarium wilt,42 were resistant,61 were mid-resistant,15 were susceptible and 1 was highly susceptible.While 9 were highly resistant to powdery mildew,42 were resistant,72 were mid-resistant,and 3 were susceptible.Under composite inoculation condition,PI164331 introduced from Indian was screened as resistant to both Fusarium wilt and powdery mildew.Significant positive correlations were observed between the evaluation results of single inoculation and composite inoculation,though correlation analysis of these 2 methods.
