摘　　要：为了探索适应宜昌市东部平原丘陵种植的高产优质脱毒马铃薯品种,对引进的南中552等4个早熟品种进行了多点比较试验。结果表明,费乌瑞它的产量和商品薯率均位居第一,为首选早熟品种;中薯5号块茎大、商品薯率高,可同时选用;东农303特早熟,三熟制田块可选用;南中552生育期偏长,不宜在平原作早熟品种,可在丘陵山区种植。In order to screen high-yield and high-quality detoxified potato varieties with adaptablity in the eastern plain and hill areas of Yichang City, four early-maturing varieties were compared in multi-places. The result showed that Favorita was the best early-maturing variety because of the largest output and the highest potato goods ratio. Zhongshu No.5 could be selected as alternative variety with the biggest tuber shape and higher goods ratio. Dongnong 303 was extreme early-maturing, so it could grow, in triple cropping field. The growth period of Nanzhong 552 was rather longer, it could not fit for plain areas as an early-maturing variety, but it could be planted in some hill and mountain areas.
