^a: Accessions marked “AS” were obtained from the Triticeae Research Institute, Sichuan Agricultural University, China; those marked “PI” or “CIae” were obtained from USDA-ARS. ^b: Types S (ssp. strangulata), T (ssp. tauschii) and I (intermediate forms). The SI was given by the ratio spikelet glume width/rachis segment width. Capital letters after the average SI value and standard deviations (SD) denote the results of LSD comparison (P < 0.01). ^c: Genetic lineage data according to marker genotype taken from Wang et al. (2013). L1E (L1 East) and L1 W (L1 West) represent the T type gene pool, and L2E (L2 East) and L2 W (L2 West) the S type gene pool
