Journal of Genetics and Breeding v. 48, no. 1, p. 7-16999555Summary: A morphological study of 50 synthetic hexaploid (SH) wheats (2n = 6x = 42) derived from Triticum turgidum (2n = 4x = 28) x T. tauschii [Aegilops squarrosa] (2n = 2x = 14) crosses was undertaken to establish descriptors for subsequent use in wheat breeding. Thirty-five qualitative traits of seedlings, leaves, culms, glumes, inflorescences, spikes and grains were recorded and compared for each entry. Data on 11 quantitative traits were subjected to complete linkage cluster analysis and the SH materials were grouped into 3 distinct phenotypic groups. Distinctive combinations of characters and parents were apparent in each of the 3 groups. Substantial variation existed within the materials tested
