The connection between red wine grape cultivars Plavac mali and Zinfandel (Vitis vinifera L.)

Zinfandel is the second most important red wine grape cultivar of California in terms of both, the planted acreage and production of wine. It has been speculated that Croatia might be the original home of this important variety. This research was undertaken with the aim of investigating the relatedness between Plavac mali, the major red variety of Dalmatia, and Zinfandel using DNA profiling and microsatellite markers. Microsatellite profiles were obtained for 14 Dalmatian varieties and Zinfandel at 25 polymorphic loci. The results support a parent or offspring relationship between Zinfandel and the Dalmatian cultivars Grk, Plavina and Vranac. Furthermore, they confirm that Plavac mali, the most important red wine cultivar of Croatia, is a progeny of the cross between another Croatian cultivar, Dobričić, and Zinfandel. These findings strongly support the Dalmatian origin of Zinfandel, despite the presence of the same cultivar in Italy under the name Primitivo. The performed likelihood analysis supports the genetic findings to a very high degree of probability.
