A New French Fry Processing Potato Variety'Dingshu 12'
摘要
Abstract
'Dingshu 12'was selected and developed from a cross of'Andante'as female and'D00-12-05'as male,and could be planted for French fry processing.The growth duration of'Dingshu 12'is about 115 days.It is a late maturing variety.The plant has a semi-upright growth habit,and the plant height is about 65.0 cm,with green stems,green leaves,and white flowers.The tubers are round in shape,with light yellow skin,yellow flesh,and red eyes.The eyes are of medium depth,the skin is slightly rough,and tuber set is concentrated.During the 2020-2021 Gansu provincial multi-site joint potato variety trials,'Dingshu 12'yielded 1 998 kg/667 m2,representing a 2.83%increase over the control variety'Longshu 6',although the difference was not statistically significant.This variety has 24.10 g/100g of dry matter,17.76%of starch content,2.59 g/100g of crude protein,11.80 mg/100g FW of vitamin C,and 0.10 g/100g of reducing sugar.It is moderately resistant to late blight,and resistant to potato virus X(PVX)and highly resistant to potato leafroll virus(PLRV).'Dingshu 12'is suitable for planting in the arid and semi-arid areas,and the area of high altitude with cloudy,cool and humid climates in Dingxi City,Jinchang City and Linxia City,Gansu Province.关键词
