Other claims from this paper (12)
- Observation The grape accessions carried 94 microsatellite alleles with extensive polymorphism.
- Observation Grape accessions formed 16 genetic groups in three clusters.
- Observation The groups supported occidentalis, pontica and orientalis eco-geographic grouping.
- Observation French cultivars were distinct and close to wild sylvestris.
- Observation Table and wine cultivars were appreciably differentiated.
- Observation Muscat types were distinct within wine grapes.
- Observation Allele frequencies differed significantly among groups at all loci.
- Observation Group heterozygosity ranged from 0.625 to 0.9.
- Observation Overall average heterozygosity was 0.771.
- Observation Genetic relationships suggested hierarchical differentiation in cultivated grape.
- Observation Most grape variation was within groups, approximately 85%.
- Mechanism The authors infer a single complex gene pool shaped by selection and vegetative reproduction.
