Comprehensive Evaluation of Yunnan Potato Landraces: Agronomic, Sensory, and Nutritional Traits

This study focused on 48 landraces from Yunnan Province, with seven commercially bred varieties as controls. Descriptive analysis and variance analysis were employed to evaluate the landraces across various aspects, including agronomic traits, tuber characteristics, and quality attributes. The resul...

description This study focused on 48 landraces from Yunnan Province, with seven commercially bred varieties as controls. Descriptive analysis and variance analysis were employed to evaluate the landraces across various aspects, including agronomic traits, tuber characteristics, and quality attributes. The results indicated that compared with commercial varieties, landraces exhibited unique appearances with deeper eyes and smaller and irregularly shaped tubers. In terms of texture, landraces had greater firmness and poorer mealiness but possessed a richer potato flavor, resulting in higher overall scores than commercial varieties. The mineral content of landraces was slightly lower than that of commercial varieties but similar to that of Andean landraces. The starch from landraces demonstrated better thermal stability but was more prone to retrogradation. Textural properties showed that landraces had greater hardness, cohesiveness, springiness, and chewiness compared with commercial varieties, indicating a denser texture, poorer mealiness, greater firmness, and consistent results with the sensory evaluation. In summary, landraces represent crucial genetic resources in breeding programs. A comprehensive study of the sensory characteristics, agronomic traits, and mineral content of landraces is essential for effectively utilizing these resources to broaden the genetic base of potato germplasm.
