摘　　要：北方008是以春薯2号为母本、中薯5号为父本,通过有性杂交选育而成的中晚熟马铃薯新品种。该品种生长势强,株型类型为直立型,从出苗到成熟100 d。薯块扁圆形,薯皮淡黄色,薯肉白色,薯皮略麻,芽眼浅,结薯集中。单株结薯数6.5个,单株块茎质量0.90 kg,大、中薯率77.5%。平均667 m^(2)产量2439.62 kg。块茎干物质含量(w,后同)13.9 g·100 g^(-1)、淀粉含量11.9 g·100 g^(-1)、还原糖含量0.53 g·100 g^(-1)、粗蛋白含量1.4 g·100 g^(-1)、维生素C含量25.3 mg·100 g^(-1)。对晚疫病表现高抗;抗马铃薯X病毒(potato virus X,PVX)、马铃薯Y病毒(potato virus Y,PVY)。2020年通过农业农村部非主要农作物品种登记。Beifang 008 is a new potato variety bred by crossing Chunshu No.2 as female parent and Zhongshu No.5 as male parent.It is a mid-late mature fresh variety.The variety had strong growth potential and upright plant type,and lasted for 100 days from emergence to maturity.The tuber type is oblate,the skin color is light yellow,the flesh color is white,and the skin type is slightly hemp,shallow eye.The potato is concentrated.The number of tubers per plant is 6.5 potatoes,and the mass of tuber per plant is 0.90 kg,and the ratio of large and medium tubers is 77.5%.The average yield is 2439.62 kg per 667 m2.The dry matter content of the tuber is 13.9 g·100 g^(-1),while starch content is 11.9 g·100 g^(-1),reducing sugar content is 0.53 g·100 g^(-1),crude protein content is 1.4 g·100 g^(-1),vitamin C content is 25.3 mg·100 g^(-1).The variety is highly resistant to late blight,resistant to the virus of PVX and PVY.
