基　　金：国家冬作马铃薯品种试验项目(农技种[2021]83号)。

摘　　要：【目的】测试南方冬作组马铃薯新品种在北海市种植的丰产性、抗逆性、适应性等综合性状,为丰富北海市冬作马铃薯品种、品种合理布局及推广应用提供科学依据。【方法】引进“中薯566号”“桂农薯4号”“华渝5号”“泉农薯6号”“闽薯5号”“费乌瑞它”共6个马铃薯品种进行比较试验,以“费乌瑞它”作为对照,调查不同品种的生育期、块茎性状和经济性状,并测定其产量。【结果】“桂农薯4号”“泉农薯6号”和“中薯566号”出苗率较高;“中薯566号”和“闽薯5号”产量分别达到3380.02 kg/667 m^(2)、3288.24 kg/667 m^(2),分别比对照种增产32.94%和29.33%,位居第一位和第二位;“中薯566号”晚疫病发病率最低,高抗早疫病;“桂农薯4号”晚疫病发病率较低,高抗早疫病。【结论】结果表明“桂农薯4号”综合表现良好,建议在当地进一步试验示范,“中薯566号”产量是最高的,抗病性较强,但空心率偏多,也可适当种植。【Objective】The comprehensive traits such as high yield,stress resistance and adaptability of the new potato varieties of winter cropping group in South China were tested in Beihai City,so as to provide scientific basis for enriching the varieties,rational distribution,popularization and application of winter cropping potato varieties in Beihai City.【Method】Six potato varieties,“Zhongshu No.566”,“Guinongshu No.4”,“Huayu No.5”,“Quannongshu No.6”,“Minshu No.5”and“Favorita”,were introduced to conduct a comparative test,with“Favorita”as a control.The growth period,tuber traits and economic traits of different varieties were investigated,and their yield were determined.【Result】The seedling emergence rates of“Guinongshu No.4”,“Quannongshu No.6”and“Zhongshu No.566”were higher.The yield of“Zhongshu No.566”and“Minshu No.5”reached 3380.02 kg/667 m^(2) and 3288.24 kg/667 m^(2),respectively,which were 32.94%and 29.33%higher than that of the control,ranking the first and second.“Zhongshu No.566”had the lowest incidence of late blight and high resistance to early blight;“Guinongshu No.4”had low incidence of late blight and high resistance to early blight.【Conclusion】The results showed that the comprehensive performance of“Guinongshu No.4”was good,and it was suggested to further test and demonstrate in the local area.The yield of“Zhongshu No.566”was the highest,and the disease resistance was strong,but the hollow rate was more,and it could also be planted appropriately.
