NDVI, normalized difference vegetation index, measured on the 21st day counting from sowing; CHL, chlorophyll index, measured on the 24th day counting from sowing; CSGP, Chinese soybean germplasm population. h2, trait heritability. R2, genetic contribution of a QTL; A QTL is designated as qNdvi-01-1, where -01 represents chromosome 1, and -1 represents its order on the chromosome; No. alleles: number of alleles in a SNPLDB; -lgP, P-value in the log10 scale of the association test in the RTM-GWAS. The corresponding SNPLDB of a QTL and its position are shown in Supplementary Table 2.
