Genetic analysis of grapevine cultivars from the Eastern Mediterranean region of Turkey, based on SSR Markers

Türkiye, asma genetik kaynaklarının önemli merkezlerinden birisidir. Ülkenin bazı bölgelerinde hala yaygın sekilde yetistiriciligi yapılan birçok yöresel üzüm çesidi bulunmaktadır. Bu bölgelerden biri Dogu Akdeniz Bölgesidir. Bu çalısmada, bölgenin asma gen kaynaklarının tanımlanması amacı ile 14 SSR primeri kullanılarak 59 üzüm çesidinin genetik analizleri yapılmıstır. Çalısma sonucunda çesitler arasındaki genetik iliskilerin bölge içindeki ekocografik dagılımları ile baglantılı olmadıgı belirlenmistir. Çalısmada analiz edilen çesitler arasında farklı isimlerle anıldıgı halde aynı genotip (sinonim) veya aynı isimli ancak farklı genotip özelligi (homonim) gösterenler saptanmıstır. Bölgenin asma genotipleri ile ilgili ilk genetik analiz sonuçlarının sunuldugu bu çalısma, gen kaynaklarının daha etkin kullanımını ve ıslah programlarını destekleyecektir.

Türkiye Doğu Akdeniz bölgesi üzüm çeşitlerinin SSR Markörleri ile genetik analizi

Turkey is one of the centres for grapevine diversity with many local grapevine cultivars with potentially desirable characteristics are still widely cultivated throughout several regions in the country. One of such regions is the Eastern Mediterranean region of the country. To characterize the grapevine germplasm of this region, we performed a genetic analysis of 59 grapevine cultivars using 14 simple sequence repeat (SSR) loci. The genetic relationships of the cultivars which did not appear to be linked to their ecogeographical distributions within the region were determined. Among the cultivars analyzed in this study, several synonymous and homonymous cultivars were identified, suggesting that some of the grapevine cultivars with different names might be genetically identical while some cultivars with the same names might be genetically different. This study represents a first step toward the genetic characterization of the grapevine genotypes of this region and will help promote more effective germplasm management and breeding programs.
