Summary
A sample of 457 (Avena sterilis L.) accessions from the World Oat Collection maintained at the Germplasm Laboratory, Beltsville, Maryland, USA, was studied by multivariate analyses to explain the phenotypic relationships among the entries. According to these analyses, patterns of seed trait associations suggest that diversity may have geographic patterning. For example, the accessions from countries and islands of the western Mediterranean tend to have a common set of traits. Number of spikelets per panicle and groat weight and dimensions were important traits that discriminated the A. sterilis accessions into the group. It was concluded that region-specific adaptations are responsible for occurrence of certain traits and trait associations in specific geographic regions.
