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

<p>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.</p><p>*Significant at P = 0.05, **Significant at P = 0.01.
