摘要

‘冀张薯28号’是张家口市农业科学院2013年利用‘白头翁’作母本，‘黄皮’作父本进行有性杂交，经多代系谱法选育而成的中熟优质鲜食马铃薯新品种，于2024年通过农业农村部非主要农作物品种登记，登记编号为GPD马铃薯（2024）130062。该品种生育期为85 d，植株呈直立型，茎色为绿色带有褐色，叶色为绿色，花冠呈白色，花繁茂性为茂盛，天然结实性为中等；块茎椭圆形，薯皮白色，薯肉白色，芽眼浅平，薯皮光滑。单株结薯数4.2个，单株结薯重0.9 kg，商品薯率为85.6%，折合产量为2 787 kg/667m²。其干物质含量为16.8%，淀粉含量为12.8%，蛋白质含量为1.96%，维生素C含量为24.0 mg/100 g，还原糖含量为0.64%，蒸煮加工品质好，食味优良。中抗晚疫病，抗早疫病，抗马铃薯X病毒（Potato virus X，PVX）病。适宜在河北省马铃薯一季作区张家口市和承德市进行春季种植。

Abstract

The new medium-maturing table potato variety 'Jizhangshu 28' was developed from a cross using 'Anemone' as the female parent and 'Huangpi' as the male parent made by Zhangjiakou Academy of Agricultural Sciences in 2013. It was bred by multiple generations of pedigree selection. It was registered by the Ministry of Agriculture and Rural Affairs of China in 2024, with the registration number GPD Potato (2024) 130062. Its growth period is 85 days. The variety exhibits an erect growth habit with green stems tinged with brown, green leaves, abundant white corollas and moderate natural fruit setting. Tubers are elliptical with smooth white skin and white flesh, and shallow eyes. This potato variety exhibited key agronomic traits including an average of 4.2 tubers per plant and a tuber yield of 0.9 kg per plant, achieving a marketable tuber percentage of 85.6%. The equivalent yield reached 2 787 kg/667m². Nutritional analysis revealed a dry matter content of 16.8%, starch content of 12.8%, protein content of 1.96%, vitamin C content of 24.0 mg/100 g FW, and reducing sugar content of 0.64%. The quality of the steaming and boiling is good, and the taste is excellent. It displayed intermediate resistance to late blight, along with resistance to early blight and potato virus X (PVX). It is suitable for spring planting in the single-cropping potato regions of Zhangjiakou City and Chengde City, Hebei Province, China.
