摘要

‘蒙薯22号’是呼伦贝尔市农牧科学研究院利用美国品种‘大西洋’作母本，自主选育品种‘内薯7号’作父本配制组合选育而成的中熟淀粉加工型马铃薯新品种。2025年通过非主要农作物品种登记，登记编号为GPD马铃薯（2025）150111。生育期85 d。块茎短卵圆形，芽眼浅，薯皮黄色略麻，薯肉浅黄色，大中薯率83.70%。2023—2024年国家区域试验多点次平均产量2 566 kg/667m²，较对照‘克新27号’增产7.70%。块茎干物质含量23.40%，淀粉含量16.37%，粗蛋白质含量2.73%，维生素C含量32.30 mg/100 g，还原糖含量0.31%。感马铃薯X病毒（Potato virus X，PVX）和马铃薯Y病毒（Potato virus Y，PVY），中感晚疫病。该品种适宜在内蒙古自治区呼伦贝尔市、黑龙江省哈尔滨市、克山县等北方一作区春季种植。

Abstract

'Mengshu 22' is a new medium-maturing starch processing potato variety bred by the Hulunbuir Academy of Agriculture and Animal Husbandry Sciences from a cross using the American variety 'Atlantic' as the female parent and the domestically selected variety 'Neishu 7' as the male parent. It was registered as a non-major crop variety in 2025, with the registration number GPD Potato (2025) 150111. The growth duration of the variety is 85 days. The tuber is short oval shaped, with shallow eyes, yellow and slightly rough skin, light yellow flesh, and a large-to-medium tuber rate of 83.70%. The average yield across multiple locations in the 2023—2024 national regional trials was 2 566 kg/667m² representing a 7.70% increase compared to the control variety 'Kexin 27'. The Tuber contains 23.40% dry matter, 16.37% starch, 2.73% crude protein, 32.30 mg/100 g vitamin C, and 0.31% reducing sugar. It is susceptible to potato virus X (PVX) and potato virus Y (PVY), and moderately susceptible to late blight. This variety is suitable for spring planting in the northern one cropping regions such as Hulunbuir City in Inner Mongolia Autonomous Region, Harbin City and Keshan County in Heilongjiang Province.
