Table 2. Three parameters were estimated: (1) The number of spinach accessions in each cluster was list by region (up section in the table); (2) the percentage of accessions in each cluster was listed by region and the data were shown in each row (the middle section in the table); and (3) the percentage of accessions in each region was listed by cluster and the data were shown in each column (bottom section in the table) in the 268 USDA spinach germplasm accessions.
