Abstract
We report the morphological typing of 13,337 accessions of bread wheat. The individual characters assessed were: awnedness, awn colour, glume colour, presence/absence of glume hairs, spike type, spike density, spike branching, grain colour, stem type (hollow/solid) and presence/absence of ligules. We have associated these morphological data with accession provenance, to analyse global patterns of the traits. Whereas some of the traits (awnedness, awn colour, glume colour, presence/absence of hairs on glumes, stem type) are concentrated in distinct geographical regions, others (spike type, spike density, grain colour, presence/absence of ligules) appear to be randomly distributed. Spike branching was not observed. Possible reasons for the geographical distributions of the characters, in the light of their inheritance, are discussed.
