Identification of vegetable properties of nectarine and peach hybrids and availability some SSR markers in early selection

This experiment was carried out to develop high chilling, late ripening peach and nectarine cultivars. Late cultivars Venus and Stark Red Gold nectarines were individually crossed with cv. Ustun peach, resulting 61 genotypes from VxU combination and 115 genotypes from SRGxU combination. At total of 176 genotypes were investigated for the morphological and phenological characteristics, then analyzed for pomological features. Some of pomological characters were compared by using BPPCT009, MA014, MA040 and STS-OPAG8 SSR primers to investigate the effectiveness of the marker selection in F1 genotypes. Due to Weighted Ranking method, VxU-55, VxU-41, VxU-34, VxU-14, VxU-1, VxU-13, VxU-24, VxU-26 peach genotypes and VxU-31, VxU-42, VxU-53, VxU-15 nectarine genotypes in VxU combination gave the highest points. In SRGxU combination, SRGxU-101, SRGxU-28, SRGxU-88, SRGxU-84, SRGxU-36, SRGxU-57, SRGxU-23, SRGxU-92, SRGxU-93 peach and SRGxU-5 nectarine genotype gave the highest points same scaling as well. No amplification was obtained from the PCR reactions among VxU and SRGxU populations analyzed by MA040 and STS-OPAG8 SSR primers. BPPCT009 and MA014SSR primers were also insufficient to determine fruit shape and free stone characteristics of VxU and SRGxU populations.
