包头地区马铃薯新品种引进及筛选

Introduction and Screening of New Potato Varieties in Baotou Area

包头地区马铃薯种植品种单一,连作现象突出,造成马铃薯产量和品质逐年下降,病害加剧。该研究从国内多地引进早熟、中熟和晚熟品种共14个,以期筛选出适宜包头地区栽培的优质马铃薯新品种。结果表明,早熟品种‘中薯3号’不仅产量和品质表现优良,而且较‘费乌瑞它’生育期缩短10 d,可以提早上市,增加经济效益;中熟品种‘延薯4号’综合表现优良;晚熟品种中建议推广种植‘青薯9号’和‘冀张薯8号’。

Potato varieties planted in Baotou area are just few, and continuous cropping of potato is common, leading to severe diseases and thereby low quantity and quality of potatoes produced. In this research, 14 varieties of early,medium and late maturity were introduced and screened in order to select out high quality varieties suitable for planting in Baotou area. Early maturing variety ＇Zhongshu 3＇ was not only high yielding and high quality, but also 10 days less in growth duration than that of ＇Favorita＇, which would make it earlier for market with good economic benefits. Medium maturing variety ＇Yanshu 4＇ was good in both yield and quality. In terms of late maturing varieties, it is suggested that＇Qingshu 9＇ and ＇Jizhangshu 8＇ be planted.
