^aHQ variation: High Quality variations number. Here, it refers to the variations without any missing data and heterozygotes.

^bThe landrace and weedy types were investigated using the program PowerCore.

^cAs defined by the program ADMIXTURE using ~1.6 M nuclear genome SNPs. indica (IND type), japonica (JAP type).

^dWild rice were from the Xu et al. (Xu et al.)⁴⁴.
