Selection and Breeding of a New Medium-early Maturing Potato Variety'Baoshu 4'
摘要
Abstract
'Baoshu 4'was a new medium-early maturing table potato variety developed from a cross between'Zaodabai'(female parent)and'Zhongshu 3'(male parent).It was registered under the Non-major Crop Variety Registration system in 2025,with the registration number GPD Potato(2025)150140.The plants have a spreading growth habit,with a growth period of approximately 75 days.The tubers are slightly flattened-round,with light yellow skin and yellow flesh,and very shallow to shallow eyes.Tuber set is concentrated,and the proportion of large-and medium-sized tubers is approximately 95%.In regional trials from 2020 to 2021,'Baoshu 4'yielded an average of 2 621 kg/667m2,which was a 12.30%increase over the control variety'Zhongshu 3',and a marketable tuber rate of 94.28%.In production trials from 2023 to 2024,the average yield was 9.39%higher than that of the control'Favorita'.The tuber of this variety has a dry matter content of 18.80 g/100g,starch content of 13.20 g/100g,protein content of 1.99 g/100g,vitamin C content of 3.94 mg/100g and reducing sugar content of 0.63 g/100g,and has a palatable,fragrant taste.'Baoshu 4'is moderately resistant to potato virus X(PVX)and potato virus Y(PVY),but highly susceptible to late blight.It is suitable for spring cultivation in the northern potato-growing regions such as Baotou,Hohhot,and Ulanqab in the Inner Mongolia Autonomous Region,and can be relay-cropped with crops like Chinese cabbage or cabbage after harvest.关键词
