Sažetak
Pošip bijeli (Vitis vinifera L.) is one of the most important white wine cultivars in Croatia, and the very first white wine with protected geographical origin. Recent research results of scientists from the University of Zagreb, Faculty of Agriculture, proved its uniqueness, however, until recently the origin of Pošip remained unsolved. In this paper, we present genetic and ampelographic evidence that Pošip bijeli is the progeny of a cross between two other autochthonous Croatian wine cultivars, namely Zlatarica blatska b. (hermaphrodite) and Bratkovina b. (female), both grown on the island of Korčula. The proposed family combination is true at 24 SSR loci. Based on the base pair data, a computer assisted search for parents was performed in an existing UC Davis database with over 300 profiled cultivars from all over the world. Due to high degree of relatedness in a group of Croatian cultivars, up until 19 loci, there were many possible parental combinations. However, upon addition of data for six more loci, the search resulted in no other, even remotely possible, parental combination for Pošip. Ampelographic analysis was performed according to the O.I.V. descriptor list (1983) modified by EU project GENRES 081 (1999). The results support a close relationship between these three cultivars, according to 27 out of 58 shared morphological characteristics. Out of the remaining 31 determined characteristics, Zlatarica blatska b. and Pošip b. shared 16, and Bratkovina b. and Pošip b. shared seven characteristics. The progeny, Pošip b., exhibited intermediary or nonparental values only in eight ampelographic traits. Thus, the display of morphological characteristics of Pošip b. clearly points to Bratkovina b. and Zlatarica blatska b. as the logical parental combination, in support of genetic evidence. The fact that Pošip b. inherited positive characteristics from both parents explains why this cultivar took over the lead and replaced some other white wine cultivars in Dalmatian viticulture.
