Breeding of a New Medium-maturing High-starch Potato Variety'Kexin 47'
摘要
Abstract
The new high-starch potato variety'Kexin 47'was developed by the Keshan Branch of Heilongjiang Academy of Agricultural Sciences.The breeding method is sexual hybridization,with the female parent being'Kexin 17'and the male parent being'Kexin 27'.GPD Potato(2025)230012 is the registration number for a non-major crop variety under the Ministry of Agriculture and Rural Affairs.This variety is a medium-maturing variety,with a growth period of 88 days from emergence to senescence.The plant height is 48.7 cm,with a semi-upright plant type,moderate branching,white corolla color,nearly pentagonal corolla shape,thick and green stem,and microwave-shaped stem wings.The tubers are set in a concentrated manner,short oval in shape,with yellow russet skin and creamy-white flesh.Eye depth is moderate,and large-and medium-sized tubers account for 89.42%of the yield.The variety exhibits excellent culinary quality.It contains 27.60%dry matter,21.00%starch,2.32%protein,30.63 mg/100g vitamin C,and 0.27%reducing sugar.'Kexin 47'exhibits moderate resistance to potato virus X(PVX),potato virus Y(PVY),and potato late blight.The average yield in the regional trial of the breeding consortium from 2022 to 2023 was 3 050 kg/667m2,representing an average increase of 52.6%over the control'Dongnong 310'.'Kexin 47'is suitable for cultivation in various ecological zones of Heilongjiang Province.关键词
