%X Aim Our objective was to understand differences in grain yield and wateruse efficiency among wheats of different ploidy. Methods We conducted experiments on six wheat varieties: diploid species (Triticum boeoticum, T. monococcum), tetraploid species (T. dicoccoides, T. dicoccon) and hexaploid species (T. aestivum Changwu 134 and Shaan 253). These were treated with different water conditions in the grain-filling stage, and we determined root bio-maSD, aboveground biomaSD, grain yield, water consumption for t...
