Fig 2.
Venn diagram comparing the genotype list based on low P tolerance exhibited for traits SL, RL, RHD and RHL.
The graphical comparison was analyzed based on genotypes’ performance for SL, RL, RHD and RHL under Pdef. The SDW and RDW were not used for graphical comparison. The graphical comparison identified 12 (9.40%) genotypes as low P tolerants, which produced higher values for traits SL, RL, RHD and RHL.

Pearson’s correlations among the predicted trait means under Psuf (lower diagonal) and Pdef (upper diagonal) conditions.
The diagonal values (bold) are the correlations between the P levels.
