Ye, G. N.; Soylemezoglu, G.; Soylemezoglu, G.; et al. Federal Research Centre for Cultivated Plants (Julius Kühn-Institut) 2015. doi:10.5073/vitis.1998.37.33-38
Other claims from this paper (10)
- Method / resource The 53 primers generated 464 bands, 29% shared by all tested genotypes.
- Method / resource Cluster analysis placed tested cultivars into Vitis vinifera and V. x Labruscana groups.
- Observation No RAPD polymorphism was detected among the named Chardonnay clones.
- Observation No RAPD polymorphism was detected among the named Pinot noir clones.
- Observation Pinot Meunier, Pinot gris and Gamay Beaujolais patterns were indistinguishable from Pinot noir.
- Observation Auxerrois and Melon had unique patterns and may be distinct cultivars.
- Observation Chardonnay clone 7 shared 84% of bands with Pinot noir.
- Observation Niagara and two supposed sports had over 97% RAPD amplicon homology.
- Observation Concord and a red-fruited sport had over 97% RAPD amplicon homology.
- Method / resource RAPD patterns distinguished phenotypically similar cultivars and assessed supposed sport origins, although they did not distinguish known clones.
