The new potato variety'Kunshu 9'is a middle-maturing potato variety developed by the Kunming Academy of Agricultural Sciences(KAAS)through artificial sexual hybridization,using variety'Hui-2'as female and variety'CIP004(TPS-67)'introduced from the International Potato Centre(CIP)as male.It was registered as a national non-main crop variety in 2023,registration number:GPD potato(2023)530042.The variety has a growth duration of about 105 days,and it is suitable for use as a table variety.The tubers are round,with a few shallow eyes,smooth,yellow skin,and yellow flesh,which contains 14.00%of dry matter,10.40%of starch,2.15%of protein,23.20 mg/100 g of Vitamin C,and 0.64%of reducing sugar(calculated based on glucose).This variety is resistant to storage and transportation,with excellent cooking quality and good palatability.It is resistant to bacterial wilt,but susceptible to late blight and potato leafroll virus.In 2013 and 2014 variety comparison test,the yield was increased by 66.20%and 76.82%,respectively,compared with the control'Hezuo 88'.In 2019-2020 winter planting regional trial at the four sites,the average yield of'Kunshu 9'was 3283 kg/667m^(2),which was reduced by 13.11%compared with the the average yield of the control'Lishu 6'(3778 kg/667m^(2)).The average yield of'Kunshu 9'at the four sites in 2020-2021 winter planting regional trial was 2864 kg/667m^(2),which was reduced by 22.14%compared with the average yield of the control'Lishu 6'(3678 kg/667m^(2)).This variety is suitable for planting in spring,fall and winter cropping areas in Yunnan Province.
