Additional file 2 of Identification of loci and candidate gene GmSPX-RING1 responsible for phosphorus efficiency in soybean via genome-wide association analysis

Additional file 2: Table S1. Correlation coefficients of three P-efficiency traits in natural population under two P conditions. SDW: shoot dry weight; SP: shoot P concentration; SPA: shoot P accumulation. The correlation coefficients of natural populations under +P (0.5 mM KH2PO4) and -P (0.005 mM KH2PO4) conditions were listed in the upper right and lower left of the table, respectively. ns: not significant; *, **and *** significant at 0.05, 0.01 and 0.001 probability levels, respectively.
