摘要
Abstract
The new potato variety'Longshu 25'was developed from a cross between'LK99'(female)and'Datong G-13-1'(male)through sexual hybridization and selection,and approved as a non-staple crop variety by the Ministry of Agriculture and Rural Affairs in 2024,with the registration number GPD Potato(2024)620040.The growth duration of'Longshu 25'is about 98 days,making it a mid-late maturing variety,and can be cultivated as table potatoes.The plant type is semi-erect.Stolons are short,and tuber number per plant is 4.9.The tuber is oval,with yellow skin,light yellow flesh,shallow eyes,and a marketable tuber percentage exceeding 81.30%.The average yield of'Longshu 25'in the two-year potato regional trials in Gansu Province was 2 867 kg/667m2,36.29%more than the yield of control variety'LK99',which was 2 104 kg/667m2 from 2019 to 2020.Tubers have a dry matter content of 21.80%,starch content of 15.22%,crude protein content of 2.49%,vitamin C content of 14.00 mg/100 g,and reducing sugar content of 0.06%.This variety shows high resistance to late blight,with strong drought and low-temperature tolerance.It is suitable for spring planting in Gansu Province,in the single-cropping region in northern and northwestern China and for early winter planting in Guangdong Province and Guangxi Zhuang Autonomous Region,in the double-cropping region in southern China.关键词
