Fig. 1. Neighbor-joining cluster analysis based on genotypic similarity determined by amplified fragment length polymorphism analysis. Diploid entries include ‘Bozoisky-Select’, ‘Mankota’, ‘Vinall’, and ‘Swift’. Tetraploid entries include ‘Tetracan’, ‘RWR-Tetra-1’, and doubled Bozoisky-Select x tetraploids (B x T).
