中文摘要:
      采用游动孢子灌根法对205份江西省地方辣椒种质资源的辣椒疫霉菌抗性进行鉴定,分析辣椒种质接种5、9、14 d后抗性的差异。结果表明:接种后14 d病株率为0%~30.0%、30.1%~70.0%和70.1%~100%的材料分别有39、56、110份,分别占供试材料的19.02%、27.32%和53.66%;抗性表现为高抗、抗病、中抗和感病的材料分别有26、43、33和103份,分别占供试材料的12.68%、20.98%、16.10%和50.24%。分析供试材料在接种后5、9、14 d的发病情况可知,材料间发病速率存在显著差异,不同时间段材料间的病情相关性不显著,接种后14 d调查时病情发展趋于缓慢,可以此次鉴定结果来评价材料的最终抗病性。
英文摘要:
      The resistance of 205 local pepper germplasms to Phytophthora capsici in Jiangxi province was identified by drenching them with zoosperm, and the differences of resistance were analyzed at 5,9 and 14 days after inoculation. The results showed that on the 14th day after inoculation, there were 39, 56 and 110 materials with the disease rate of 0%-30.0%, 30.1%-70.0% and 70.1%-100%, respectively, accounting for 19.02%, 27.32% and 53.66% of the tested materials, respectively. There were 26,43,33 and 103 varieties showed high resistance, resistance, moderate resistance and susceptibility respectively, accounting for 12.68%, 20.98%, 16.10% and 50.24% of the tested materials, respectively. According to the analysis of the incidence of the materials, on the 5th, 9th and 14th day after inoculation, there was a significant difference in the incidence rate among the materials, and there was no significant difference in the disease correlation among the materials in different times. In this experiment, the disease developed slowly after the 14th day after inoculation, so the results represent the final resistance of the materials.
