| 摘 要： | 通过田间自然诱发和室内接种鉴定两种方法,调查评价青海省马铃薯品种对晚疫病的抗性情况。结果显示:所有18个参试品种中均有不同程度的抗病能力。室内鉴定为中抗(MR)以上的品种有8个,占总参试品种的44.44%;感病(S)品种有10个,占总参试品种的55.56%。田间鉴定为中抗(MR)以上的品种有13个,占总参试品种的72.22%;感病(S)品种有5个,占总参试品种的27.78%。室内鉴定和田间鉴定结果相同品种有5个,占总参试品种的27.78%。

| Abstract: | The resistance of potato cultivars to Phytophthora infestans in Qinghai Province were investigated and estimated by the natural infection in the field and inoculation of detached leaves in vitro.Cultivars tested had various degrees of resistance.In vitro estimation,eight cultivars with above moderate resistance were identified,accounting for 44.44%,and ten cultivars were susceptible,accounting for 55.56%.For estimation in field conditions,thirteen cultivars showed moderate resistance or more,accounting for ... |
