摘　　要：[目的]筛选适宜江淮地区春季稻草覆盖栽培的马铃薯品种。[方法]以东农303为对照品种,对10个稻草覆盖栽培马铃薯参试品种的生育期、植株形态特征、薯块性状、产量和商品薯率等性状进行调查分析,筛选适宜江淮地区春季稻草覆盖栽培的马铃薯品种。[结果]在10个参试品种中,中薯3号表现最好,产量高、薯块较大、结薯集中、芽眼中等、表皮光滑、薯形优美,且大中薯率高,高于对照12.51%;其次为费乌瑞它和郑薯5号。中薯3号、费乌瑞它和郑薯5号生育期短,薯块膨大速度快,产品上市早,经济效益好,同时不影响下茬水稻种植,适宜江淮地区春季稻草覆盖栽培。[结论]该研究为江淮地区发展稻草覆盖栽培马铃薯提供了科学依据。[Objective] The aim was to screen the potato variety suitable for mulching straw in Jianghuai area in spring. [Method] With Dongnong 303 as control variety, the characters such as growth period, plant morphological characteristics, potato tuber characters, yield and commodity potato rate of 10 tested potato varieties with mulching straw were surveyed and analyzed to screen the potato variety suitable for mulching straw in Jianghuai area in spring. [ Result ] During the 10 tested potato varieties, the performance of Zhongshu 3 was best, and its yield was high, potato tuber was big, tuber formation was concentrated, bud eye was moderate, epidermis was smooth, tuber shape was good and its big potato rate was high, which was 12.51% higher than that of the control, followed by Feiwuruita and Zhengshu 5. The growth period of Zhongshu 3, Feiwuruita and 21aengshu 5 was short, potato tuber expanding speed was fast, the products came to market earlier, their economic benefit was good and they could not affect the next stubble rice, which were suitable for mulching straw in Jianghuai area in spring. [ Conclusion] The research provided the scientific basis for the development of potato suitable for mulching straw in Jianghuai area.
