Abstract：
:A total of 41 accessions of Aglianico belonging to three different biotypes (Taburno, Taurasi, and Vulture) and 9 accessions of Sirica grapes were sampled from diverse areas of Campania (Italy). All accessions were first genotyped using 21 microsatellite markers (SSR) to evaluate possible homonymies, synonymies, and the genetic structure of each group. A larger dataset was then constructed adding Italian and International cultivars. On the basis of results obtained analyzing the first dataset, further investigations were carried out enlarging the number of investigated loci (up to 43). The addition of 22 SSRs was useful in the definition of likely genetic relationships linking Aglianico biotypes, Sirica and Syrah. According to their SSR allelic profiles, the monophyletic origin of the three Aglianico biotypes was confirmed. Among Aglianico Taburno accessions, eight samples (called Aglianico like-to-type) performed a different SSR allelic profile from Aglianico true-to-type. Sirica and Syrah proved to be synonyms. This work allowed to determine the genetic relationship between Aglianico and the cultivars supposed to be related. The parentage analysis was investigated. The most likely pedigree has been reconstructed; revealing a second-degree relationship between the worldwide cultivated Syrah from the Rhone Valley and Aglianico. Aglianico like-to-type appeared related to Aglianico in a parent-offspring fashion.
