Sixty-four genotypes originating from 6 different countries were grown in 6 different environments (seasons/sites); data on yield/plot and related traits were analysed by several methods. Mahalanobis' D2 statistic divided the materialinto 9 clusters, with membership unrelated to geographic origin. Measurement of intercluster and intracluster genetic distances identified the US material as the most genetically diverse. A number of genotypes (listed) showed stability ofperformance across environments.
