Fig. 1.

Box plots of floral phenotypic traits of wild and cultivated crabapples. The middle region of each box plot (box body) covers 50% of the individuals, and the region between the upper and the lower transverse lines covers 90% of the individuals, whereas the points outside of the box highlighted in purple represent transgressive individuals. The mean values are presented in small squares inside the box bodies. Datasets of all the wild and cultivated individuals are shown on the right of each box plots and their distributions are fitted with a line. The different lowercase letters indicate significant differences (P < 0.05) between the mean values of each floral traits from wild and cultivated crabapple groups, while different capital letters indicate highly significant differences (P < 0.01) between the mean values of each traits from these two groups. Identical letters indicate the absence of significant differences
