Comparative Trials of New Potato Varieties Introduced to the Zhaosu Reclamation Area
摘要
Abstract
Potato is one of the main food and economic crops in the Zhaosu Reclamation Area.Although the high-altitude cold ecological environment provides unique conditions for potato cultivation,it also limits the wide adaptability of varieties.Screening potato varieties(lines)with strong adaptability and excellent comprehensive traits is a key measure to enhance the local potato production efficiency.To screen for superior potato varieties(lines)suitable for cultivation in the high and cold regions of the Zhaosu Reclamation Area,23 new potato varieties(lines)were introduced.With'Qingshu 9'as the control variety,their growth period,field traits,yield and nutritional quality were determined,and a comprehensive evaluation was conducted using the membership function method.'Yingfa 1'(Y1)had the highest D value of 0.676,ranking first with a yield of 54 486 kg/ha,an increase of 22.46%compared to the control,a marketable tuber percentage of 97.0%,and a reducing sugar content of 0.03%.'Tianshu 17'(L21)had a D value of 0.539,ranking second with a yield of 52623 kg/ha,an increase of 18.27%compared to the control,and a marketable tuber percentage of 98.5%.'Longshu 11'(L2)had a D value of 0.489,ranking third with a yield of 54607 kg/ha,an increase of 22.73%compared to the control,and a marketable tuber percentage of 95.4%,and exhibited outstanding overall performance.Through the comprehensive evaluation of multiple indicators by the membership function method,it was clearly identified that these three varieties(lines)have strong adaptability and good yield,and can be used as candidate varieties for further experiments and demonstrations.关键词
