Fig. 1 Effects of chilling treatment on seed coat pigmentation in Harosoy (a) early-maturing isolines (Harosoy-e₃, Harosoy-e₄) and (b) late-maturing isolines (Harosoy-E₁, Harosoy-E₂, Harosoy-E₅). Pigmentation index is 0 to 4 (0 = not pigmented; 4 = severely pigmented). Bars indicate standard error of the mean; numbers at each data point represent the number of seeds obtained from flowers exposed to chilling at a similar stage
