Abstract

Smokva je jedna od najstarijih voćnih vrsta svijeta ĉiji je intezitet uzgoja u Hrvatskoj varirao od potpune zanemarenosti do postupne revitalizacije i popularizacije ĉime se postavlja pitanje strukture i pouzdanosti postojećeg sortimenta. Izbor i dostupnost razliĉitih sorata smokve danas je usko povezan s ponudom rasadnika koji garantiraju genotip soritmenta. MeĊutim, u sluĉaju smokve vidljiva je fenotipska neujednaĉenost novih nasada, a u struĉnoj literaturi navode se tek osnovni opisi sorata. Brojni sluĉajevi sinonima i homonima upućuju na neusustavljenost sortimenta, odnosno na mogućnost heterogenosti populacija sorata. Cilj ovog istraţivanja bio je primjenom metoda genetiĉke i pomološke identifikacije provjeriti status jedinstvenosti i genetske uniformnosti tri ekonomski vaţne sorte smokve u Hrvatskoj. Analizom genotipa pomoću mikrosatelitskih markera na sedam lokusa i izabranim IPGRI deskriptorima, utvrĊena je heterogenost sorata unutar i izmeĊu proizvodnih i matiĉnih nasada, otvorena su pitanja identiteta pojedinih sorti i vjerodostojnosti drţavnih kolekcijskih nasada smokve. UtvrĊena je potreba za opseţnijim istraţivanjem na većem broju sorata i većem uzorku, a uz genotipizaciju molekularnim markerima nuţno je provesti i temeljite pomološke analize kako bi se ustanovio osnovni genotip i glavno ime sorata te pratećih sinonima gospodarski vaţnih sorata smokve.

Abstract (english)

The fig is one of the oldest fruit species in the world, the intensity of cultivation in Croatia varied from complete neglect to gradual revitalization and popularization, which raises the question of the structure and reliability of the existing variety lists. The choice and availability of different varieties of figs today is closely related to the offer of nurseries that guarantee the true-to-type genotype of the variety. However, in the case of figs, the phenotypic unevenness of the new plantings is visible, and only basic descriptions of the cultivars are given in the professional literature. Numerous cases of synonyms and homonyms point to the non-consistency of variety genotype, that is, to the possibility of heterogeneity of the variety populations. The goal of this research was to verify the status of genetic uniqueness, distinctness and uniformity of three economically important fig varieties in Croatia by applying genetic and pomological identification methods. Genotype analysis using microsatellite markers at seven loci and selected IPGRI descriptors determined the heterogeneity of cultivars within and between production and mother plantations, opened questions about the identity of individual cultivars and the credibility of national fig collections. There is need for more extensive research on a larger number of cultivars and based on larger sample. Both, molecular marker genotyping, as well as appropriate pomological analyzes would be necessary in order to establish the true-to-type genotypes and prime names of the economically relevant fig cultivars.
