Abstract
Present study was aimed to select superior genotypes within olive populations of Adıyaman, Mardin, Åžanlıurfa and Şırnak provinces in South East Anatolia, leading fruit and tree characteristics were determined in shoot, leaf and fruit samples collected from 142 genotypes. These genotypes were investigated according to “Weighted Rankit” method using fruit weight, number of fruits per 100g, flesh/seed ratio, oil ratio, fatty acid composition, habitus, lenticel size, length of internode and 38 promising genotypes as cultivar candidate (20 are table olives and 18 are olive oil) were selected. Among table genotypes, number of fruits per 100 g between 11 (Yurteri-4) and 25 (Derik-20 and Yedi kardeÅŸler-1), flesh/seed ratio between 5.85g (Yardere-2) and 11.40g (Yedi kardeÅŸler-3) and oil content between 3.0% (Eski kale) and 13.0% (Amak-1); among oil genotypes, fruit weight between 1.14g (Derik zeytin pınarı-2) and 8.99 g (Yurteri-4), flesh/seed ratio between 2.73 g (Zinnar-5) and 11.40 g (Yedi kardeÅŸler-3); oil content between 2.0% (Eski kale çıkışı) and 13.0% (Amak-1), oleic acid ratio between 63.25% (GürmeÅŸe-2) and 74.31% (Yurteri-6) and linolenic acid ratio between 0.49% (Yedi kardeÅŸler-1,Eski kale çıkışı) and 1.42% (BeÅŸdeÄŸirmen-2) were changed. Genetic characterization of 38 selected table and olive (Olea europaea L.) genotypes together with 6 local and 4 foreign reference cultivars obtained from Alata Horticultural Institute was performed using 10 microsatellite markers ((UDO4, UDO9, UDO12, UDO24, UDO26, DCA9, DCA11, DCA13, DCA15 and DCA18) and their genetic similarities were investigated by SSR method. Number of alleles per locus was determined between 7 (UDO9 and UDO24) and 16 (DCA18) for table genotypes and between 4 (UDO4) and 15 for oil genotypes (DCA11ve DCA18). Mean expected and observed heterozygosity were determined as 0.694-0.604 among table genotypes and 0.710 and 0.656 among oil genotypes, respectively. The dendrogram obtained from cluster analysis consisted of two main groups. Several sub-groups were observed within the first group which consisted of the majority of genotypes. This data was further supported by the AFLP analysis. Homonyms and synonyms were not obtained. Close genetic similarities were determined between Amak-1 and Yedi kardeÅŸler-3 in table genotypes and between. Zinnar-5 and Yurteri-4, between. GürmeÅŸe-1 and GürmeÅŸe-2 in oil genotypes.
