摘要
引进13个马铃薯（Solanum tuberosum)品种进行了比较试验。结果表明，中薯13号\克新22号和克新23号生育期在90 d以内，为中早熟品种，每667 m2产量分别为2995.7\2583.2\3063.1 kg，较对照增产57.37%\35.70%\60.90%，比较适合在二季作地区种植推广；克新18号\克新19号和中薯17号生育期在90 d以上，为中晚熟品种，每667 m2产量分别为2922.9\2871.0\2505.5 kg，较对照增产53.54%\50.81%\31.61%，适合在一季作地区推广种植。克新21号\中薯1号\中薯7号产量较低，不适宜大面积推广种植。
Abstract
Resu1ts in the comparison experiment of 13 introduced potato varieties showed that Zhongshu 13,Kexin 22 and Kenxin 23 were ear1y maturity varieties with growth period of 1ess than 90 days.Their yie1ds per 667 m2 were 2 995.7 kg, 2 583.2 kg and 3 063.1 kg,respective1y. The yie1d increase rates were 57.37%,35.70% and 60.90%, respective1y,when com-pared with CK. They were suitab1e for cu1tivation in the doub1e cropping potato region. Kexin 18, Kenxin 19 and Zhongshu 17 were mid-1ate maturity varieties with growth period of more than 90 days.Their yie1ds per 667 m2 were 2 922.9 kg,2 871.0 kg and 2 505.5 kg,respective1y. The yie1d increase rates were 53.54%,50.81% and 31.61%, respective1y, when compared with CK. They were suitab1e for cu1tivation in the sing1e cropping potato region. Kexin 21,Zhongshu 1 and Zhongshu 7 were not suitab1e for 1arge area p1anting because of their 1ow yie1ds.
