Abstract :Ekşi Kara (functional female flowers) and Gök Üzüm (hermaphroditic flowers) are the two most important autochthonous varieties of middle Anatolia. This clone selection study started with mass-selection in producer vineyards consisting of approximately 5000 vines by The International Organization of Vine and Wine (OIV) clonal selection procedure. Two-years genetic and sanitation were examined visually in population and 220 clone candidates were ampelography and fertilization biology and bud fertility determined for Ekşi Kara variety. The clone candidates were ranked at the level of sums, with weighted grading of three-year yield, growth, and quality records. Sanitation analyses of the superior clones were made. 17 clones in the Ekşi Kara grape variety were selected according to their superior scores in genetic selection and sanitation analyses. Eleven clones were selected by mass selection from Gök Üzüm carried out in a single location, and 2 clones were selected with genetic selection scores and health tests. Grapevine fleck virus (GfKV) was the most common ( 29%) in the samples tested, Grapevine leafroll-associated virus 1+3 (GLRaV-1 + 3, 26%), Grapevine virus A (GVA, 12%), Grapevine leafroll associated virus-2 (GLRaV-2, 3%), Arabis mosaic virus (ArMV) / Grapevine fanleaf virus (GFLV) ( 1%) are fallowed with indicated percentage. Although virus and bacterial infections are common in the vineyards, enough healthy clones were selected. 17 Ekşi Kara and 2 Gök Üzüm clones selected as pollinators were grafted onto the 110R rootstock for clone comparison in homogeneous conditions, and a \"Clone Comparison Vineyard\" was established in Selçuk University.Keywords : Clonal selection, clone comparison, native grape varieties, phytosanitary tests
