Phenotypic correlations among four traits related to seed vigor for four treatments in two recombinant inbred line populations.

Correlation coefficients above the diagonal line in each quadrant of the table are for the Yu537 × Shen137 recombinant inbred line, and correlation coefficients below the diagonal line are for the Yu82 × Shen137 recombinant inbred line. 0 d, control; 2d, 2-day aging treatment; 4 d, 4-day aging treatment; 6 d, 6-day aging treatment; GE, germination energy; GP, germination percentage; RDW, root dry weight; SDW, seedling dry weight. *Significant at P = 0.05, **Significant at P = 0.01.
