Other claims from this paper (8)

Method / resource Twenty-two new grape microsatellite markers were developed.
Method / resource Twelve markers were polymorphic and informative in V. vinifera.
Method / resource Five markers were monomorphic in V. vinifera.
Method / resource Five other polymorphic markers had limited usefulness because they had two alleles or amplified more than two bands.
Method / resource The twelve informative markers detected 4 to 19 alleles.
Method / resource Heterozygosity of the informative markers ranged from 0.42 to 0.90.
Method / resource Primer sequences and allele frequencies were reported for the new markers.
Method / resource Genotypes at the twelve informative markers were provided for seven suggested reference cultivars.
