Abstract Chinese cabbage (Brassica rapa ssp. pekinensis) is a typical potassium (K)-demanding crop that is highly sensitive to soil K availability. Severe soil potassium deficiency in production fields frequently impairs both yield and quality. Therefore, screening for potassium-efficient varieties is essential for identifying germplasm resources and breeding materials tolerant to low-K conditions. To evaluate genetic variation in potassium utilization efficiency, 12 Chinese cabbage germplasms were assessed under two field conditions: with adequate potassium supply (K2O 165 kg/ha) and without potassium application (K2O 0 kg/ha). Fourteen parameters, including yield, plant growth, potassium content, and potassium accumulation, were measured and compared.… More >
