Identification of Wx allelic type for superior taste quality and genomic selection signals. a Amylose content of the sequenced 200 japonica rice varieties. NG46 with Wxmp was the first LV released in 2008. LV, low-amylose (8–12%) variety; MV, medium-amylose (13–18%) variety. b The average amylose content showed a significant downward trend after 2010; ** indicates independent-samples t-test with P < 0.001; c Genetic loci associated with rice amylose content were identified by a genome-wide association study (GWAS) using 200 japonica rice varieties. Heatmap showing the density of SNP markers (− log(P) value > 4) in 100 kb chromosome intervals. d Key SNP variations that could distinguish four allelic variants (Wxa, Wxb, Wxin, and Wxmp) of the Wx locus. e Genome-wide genetic diversity (π) and cross-population composite likelihood ratio (XP-CLR) of varieties bred before 2010 and after 2010. Genes or QTLs related to grain weight, grain number, panicle number, and amylose content that were located in selection sweeps are indicated, and the loci identified in GWAS in this study are marked in red
