  1. EN-MR = Average entry-to-nearest-entry distance according to the Modified Rogers (MR) distance using the genetic data; EN-GD = Average entry-to-nearest-entry distance according to Gower distance (GD) using the phenotype data; SH = Shannon’s allelic diversity index; He = expected heterozygosity; PIC = polymorphic information content; TFWPP = total fresh-weight per plant; TDWPP = total dry-weight per plant; FvFM = the ratio of variable fluorescence to maximum fluorescence; PI = performance index. The phenotype of the whole collection under water-deficit conditions is in parentheses. OW = optimal-water condition; WD = water-deficit condition.
