WR (Weedy rice), AKI (Akihikari), SN265 (Shennong265), QSZ (Qishanzhan), NIP (Nipponbare), WR-AVE (Weedy rice Average), CR-AVE (Cultivated Rice Average). AKI, SN265, QSZ, and NIP are control cultivated rice. The different lowercase letters in the columns of the table indicate the significant difference in the content of each component between weedy rice and control cultivated rice at p < 0.05 level. Capital letters indicate the significant difference in the content of each component between weedy rice and control cultivated rice at p < 0.01 level. The unit of the anthocyanins is (mg/g).
