通用电气netic analysis of 438 wheat accessions with 52 KASP markers.a, Ten agro-ecological zones of wheat-growing areas in China. The map information is from the National Geomatics Center of China (http://www.ngcc.cn/ngcc/).b, PCA plot of all accessions based on the KASP markers. Chinese landraces (CL) and modern Chinese cultivars (MCC) are shown in purple and orange, respectively.c, Genetic differentiation index (Fst) and gene flow analysis between CL and MCC.d, Radar map of genetic diversity (πvalue) of CL and MCC released in different decades.e, Heat map ofFst between CL and MCC released in different decades. The deeper the color, the stronger the differentiation.f, Heat map of gene flow between CL and MCC released in different decades. The deeper the color, the stronger the gene flow
