优质高产马铃薯新品种筛选试验

Study on Screening Test for New Varieties of Potato with High Quality and High Yield in Winter Fallow Fields

为筛选出高产、优质、抗性强的马铃薯新品种,以中薯5号为对照,对新引进的20个马铃薯品种在常德进行了品种比较试验。结果表明,德薯2号、中薯18号和鄂薯14号等3个品种产量、品质、抗病性表现均较好。鄂薯14号、中薯18号植株抗性强,薯形漂亮,较对照分别增产34.3%、13.5%;德薯2号植株抗性强,产量为28396.8 kg/hm^2,较对照增产8.7%,小薯多而整齐,可作特色小薯品种种植。

For breeding the new varieties of potato with high yield,good quality,and strong resistance,a comparative experiment of 20 new varieties of potato was carried out with Zhongshu 5 as control. The results showed that the yield,quality and disease resistance of Eshu 14,Zhongshu 18,Deshu 2 were better. Eshu 14 and Zhongshu 18 plants were resistant and the potato shape was beautiful. The yield increased by 34. 3% and 13. 5% respectively compared with the control. Further demonstration showed that Deshu 14 yielded 28 396. 8 kg/hm2 and increased 8. 7% compared with the control. Due to the large amount of small potato,it can be grown as a special variety to meet the market demand for fresh local small potatoes.
