Four primary varieties of tuber mustard were employed and planted in four high-altitude mountainous regions in western Sichuan,ranging from 1510 to 2936 m above sea level,with altitude differences of 500 m between them.In each of these regions,we investigated eight key agronomic traits,including plant height,plant spread,edible stem length,and so on,to explore the impact of altitude variation on the key agronomic traits of tuber mustard.The results showed that as the elevation increased,the plant height,edible stem length,and edible stem internode length exhibited trend of decreasing,the edible stem diameter and skin thickness appeared trend of increasing,the plant spread showed trend of increasing and then decreasing.Furthermore,positive correlation was observed among the gross weight per plant,net weight per plant,edible stem diameter,and edible stem skin thickness,and these traits were inversely correlated with the plant height,edible stem length,and edible stem internode length.Notably,strong significant correlation emerged between edible stem diameter and edible stem skin thickness across all four tuber mustard varieties.
