摘要: Genetic variation among 155 U.S. modern and heirloom cultivars was assessed from assays of 21 polymorphic isozyme loci. Four loci (Fdp-1, Mdh-1, Mpi-1 Pgd-1) were monomorphic. Multivariate analyses partitioned into two distinct groups: those released before 1968, after 1968. Cluster analysis produced a dendrogram with 14 nodes 28 groups. Modern European 1968 differed in frequencies. Isozymic profiles clearly discriminated some unique attributes and/or pedigrees [e.g., ‘Windermoor Wonder’ (USA), ‘Gergana’ (The Netherlands), ‘Seiram’ ‘Fancy Pak’ ‘Dasher 2’ WI 2757 (USA)].
