Abstract: 【Objective】To screen potato varieties with high phosphorus(P) efficiency to enhance phosphorus fertilizer use efficiency in the cold and arid region of North China.【Methods】Fifteen potato varieties were used as experimental materials in field trials conducted in 2021 and 2022,with treatments of no phosphorus fertilizer and phosphorus fertilizer application. Phosphorus efficiency was evaluated based on indicators including potato yield,phosphorus concentration,phosphorus uptake,phosphorus biological efficiency,agronomic efficiency of phosphorus fertilizer,partial factor productivity of phosphorus fertilizer,and apparent utilization rate of phosphorus fertilizer. A membership function analysis was employed to comprehensively evaluate the phosphorus efficiency of different potato varieties and screen them.【Results】Different potato varieties and phosphorus application levels affected fresh weight yield. Under no phosphorus fertilizer treatment,the Atlantic variety exhibited the highest yield at 51 973 kg/hm2. Under phosphorus fertilizer treatment,the North 009 variety showed the greatest yield increase of 8.22%,indicating high sensitivity to phosphorus.In 2022,under high phosphorus conditions,the dry weight yield increase ranged from 4.91% to 9.50%,with the North 009 variety showing the highest increase;under low phosphorus conditions,the dry weight yield increase ranged from 0.57% to 5.21%,with the Atlantic variety exhibiting the highest increase. Under low phosphorus conditions,the North 009 variety demonstrated the highest phosphorus biological efficiency at 465.12 kg/kg;the contribution rate of phosphorus fertilizer to yield varied from 0.56% to 8.68%,with the North 009 variety being the highest,followed by the Atlantic variety. Membership function analysis revealed that the North 009 variety had the highest comprehensive membership function value of 0.99,followed by the Atlantic variety at 0.93.【Conclusion】The potato varieties North 009 and Atlantic exhibite superior comprehensive phosphorus efficiency,making them suitable for agricultural production or as phosphorus-efficient germplasm resources.
