摘要
为摸清贵州省部分主栽马铃薯品种对晚疫病的田间抗性情况,于2015年对贵州省10个主栽马铃薯品种进行晚疫病抗性鉴定试验。结果表明:中薯20号、威玉3号、中薯5号为早熟品种,产量在18 000~24 000 kg/hm^2,对晚疫病抗性均表现为高感,适宜在黔东南州低海拔发病不重的地区推广种植,但需加强晚疫病防治,并配套高产栽培技术。wy08-002250与0501-15为晚熟品种,产量分别为1 1044.5 kg/hm^2和13 804.5 kg/hm^2,对晚疫病抗性表现为中抗,适宜在黔东南州高海拔地区种植,需配套高产栽培技术。黑美人、2015、青薯9号为中晚熟品种,产量低,对晚疫病抗性表现为中感,建议不种植或少种植。
The testing was carried out in order to sort out the resistance of 10 main varieties cultivated in Guizhou Province in 2015. The results showed that, Zhongshu-20, Weiyu-3 and Zhongshu-5 showed highly susceptible with potato late blight. Their yield were between 18 000 hm^2 and 24 000 kg/hm^2, which were early varieties, and were suitable for promotion in low altitude South-East Guizhou areas with low incidence. Also, control measures must be strengthened and high-yield techniques must be matched in their actual cultivation. wy08-002250 and 0501-15 showed moderately resistance to potato late blight. Their yield were11 044.5 kg/hm^2 and 13 804.5 kg/hm^2, respectively. They were late varieties, and were suitable for growing in high-altitude South-East areas. Also, high-yield techniques must be matched in their actual cultivation. Heimeiren, 2015 and Qingshu-9 showed moderately susceptible with potato late blight. They were medium late varieties, and their yield was low, and so they were recommended to plant less or not to grow.
