Abstract:

To optimize the potato planting structure in arid regions of northwest China and improve yield and quality, this study introduced ten varieties, including Linshu 18, with Tianshu 10 as the control. A randomized block design was adopted for field experiment conducted in Xinyi Village, Tumen Town, Qingshui County, Gansu Province. The agronomic traits, yield, quality, and disease resistance of each variety were systematically evaluated. The results showed that Qingshu 9 and Longshu 17 performed exceptionally well, with yields reaching 3 250 and 3 150 kg per 667 m2, respectively, and dry matter contents of 22.5% and 21.8%, respectively. These two varieties exhibited excellent quality, strong disease resistance, and high adaptability to local climatic and soil conditions, making them highly valuable for promotion. Although Longshuhong 1 had a slightly lower yield, its unique red flesh offered high economic value and market potential. This study provides a scientific basis for potato variety selection and industrial development in arid regions of northwest China.
