Zlatarica blatska is considered as an indigenous variety from the Korčula island. Zlatarica has been completely neglected over time, most likely because of low yields. It features a functional female type of flower, which may be a reason for her low yields. It is characterized by the sensitivity to Plasmopara viticola as well. Today the population of this variety is reduced to just several hundred grape vines. The research on this variety was carried out in the place Blato on the Korčula island from where it's most likely autochthonous. For the purposes of this research, following methods had been used: the monitoring of phenological characteristics and the ampelographic evaluation of Zlatarica blatska and its related varieties, Pošip and white Bratkovina. As these three varieties are interlinked in parenting, the research attempted to determine the advantages and positive properties of Zlatarica and to compare it with Pošip and Bratkovina bijela. The specificity of the accumulation more sugar content, the pleasant and refined aroma of grapes, which Pošip and Bratkovina do not have, is a main advantage of this variety. Defects and the main causes why this variety is neglected are functional female flower and an alternative genus. The experiences of older wine growers of Blato connect this gap with the incompatible substrate (Paulsen 1103), which is today predominantly spread in the vineyards of the island of Korčula. Zlatarica blatska has a high potential for producing top quality, fresh wines, excellent quality.
