The spring wheat area of North China (a; SNC; n = 140), winter wheat area of North China (b; WNC; n = 547), winter wheat area of North China Plain (c; WNCP; n = 1165), and winter wheat area of South China (d; WSC; n = 929). P values were obtained from a one-sided F-test for the fitting lines, and no adjustments were made for multiple comparisons.
