Jc. Bourquin et al., RESTRICTION-FRAGMENT-LENGTH-POLYMORPHISM AND MOLECULAR TAXONOMY IN VITIS-VINIFERA L, Theoretical and Applied Genetics, 87(4), 1993, pp. 431-438
Forty-six accessions of grapevine (V. vinifera L.) were compared by re
striction fragment length polmorphism (RFLP) analysis, and 111 informa
tive or unique restriction fragments were found that revealed an impor
tant level of polymorphism. RFLP patterns were compared in two ways: b
y calculating electrophoretic similarity degree values further analyze
d by principal component analysis and by studying the distribution of
rare restriction fragments. Six taxonomic groups could be defined, whi
ch partially confirmed relationships derived from ampelographical data
. Our data support the existence of ecogeographical groups.
