    (Parlar Scientific Publications (P S P), 2018) Kayra, Ridvan; Atli, Halit Seyfettin; Yavic, Adnan
    This study was conducted to determine some properties of the Amygdalus arabica Oliver almond species used as rootstocks and their production. The description of this species, seed germination of different 5 species, growth of seedlings, budding success were investigated. The kernels of almonds are bitter. Seed width is between 8.55 - 9.26 mm, seed length is between 13.76 - 15.44 mm, seed suture is between 10.62 - 11.74 mm and seed weights are between 0.60 - 0.79g. There is no problem with the germination of the seeds. The best germination rate; It was obtained as an average of 72.7% of seeds which were soaked in 250 ppm GA(3) solution for 2 days and applied to stratification for 30 days at 4 degrees C. Seedling growth of the Arabian almond has been thin, and Seedling has not reached the level of grafting for 6 months. Seedling diameter of almond types ranged from 2.74 to 3.97 mm, and the length of the seedling ranged from 18.5 to 20.0 cm. The budding work of A. arabica was carried out on the wild type at the field. Ferragnes almond variety is grafted. It seems that there is no problem with the grafting success. At Budding done in 3 periods, the best budding rate was obtained in February (50.0 - 70.0%), followed by the budding in September (30.0 - 40.0%) with the lowest budding rates from June budding (6.7 to 16.7 %). It has been concluded that A. arabica can be used as a rootstock in some stone (almond, peach, nectarine, plum, apricot) fruit species. It can also be used for afforestation and fruit cultivation in arid and semi-arid areas. These features should be evaluated by preliminary studies.

    IDENTIFICATION OF Prunus persica ROOTSTOCKS TO RESISTANT TO ROOT-KNOT NEMATODES USING MARKER ASSISTED SELECTION
    (Parlar Scientific Publications (P S P), 2022) Basbuga, Selcuk; Basbuga, Sevil; Can, Canan; Atli, Halit Seyfettin
    Prunus is an important genus in the Prunoideae subfamily of the Rosaceae family. Some species such as peach (Prunus persica), almond (Prunus dulcis), plum (Prunus cerasifera, Prunus salicina, Prunus domestica) are used as rootstocks in stone fruit production because they can adapt to harsh climate and environmental conditions. It is aimed to produce rootstocks resistant to pathogens with classical and genetic breeding studies. Root knot nematodes slow down the active growth of Primus fruit trees such as peach and almond, reduce the resistance and cause yield loss. Recently, the use of nematicides in controling root knot nematodes has been restricted and that the damage has reached greater dimensions. For this reason, it has gained importance to use root-knot nematode-resistant rootstocks against nematodes in Prunus species. DNA marker systems that show tight linkage to genes (RMia, Ma and RMja genes) that provide resistance to root knot nematodes in Prunus species have been developed and it has been reported that these systems can be used with marker assisted selection (MAS) studies. In this study, resistance against root knot nematodes of F-1 hybrid individuals obtained from Ferragnes x GN22, Nemaguard x Ferragnes, GN22 x AB3, Nemaguard x AB3, Ferragnes x Nemaguard, Nemaguard x GN22 were determined. Three markers have been identified in the parent individuals [Nemaguard, GN22, Ferragnes, AB3 (Amygdalus orientalis Mill.) and GF67] that provide polymorphic discrimination, thus allowing selection of Ft individuals. As a result of PCR analyzes performed with these markers; 82 hybrid individuals were tested with the AMPP117 primer, and it was determined that 64 individuals were resistant and 18 individuals exhibited a sensitive profile. Additionaly, 77 hybrid individuals were screened with the LRR65 primer where 29 individuals were resistant and 48 individuals exhibited a sensitive profile. Totally, 86 hybrid individuals were tested with the SSRO5I12 primer, and that 34 individuals were resistant and 52 individuals exhibited a sensitive profile. As a result, the selection of peach hybrids resistant to root knot nematodes was achieved by using the markers whose usability was reported in marker assisted selection.

    Investigation of root-knot nematode (Meloidogyne spp.) resistance in almond rootstocks with DNA markers
    (Tubitak Scientific & Technological Research Council Turkey, 2015) Turkoglu, Sultan Bay; Coban, Nergiz; Ozkan, Ali; Atli, Halit Seyfettin; Can, Canan
    Seven almond varieties, Ferragnes, Nemaguard, AB3 (Amygdalus orientalis Mill.), GN22, GF677, Myrobalan (Prunus cerasifera), and Pissardi nigra, and F-1 crossbreed almonds, Ferragnes x Pissardi nigra, Ferragnes x Myrobalan, Ferragnes x GN22, Nemaguard x GF677, Myrobalan x AB3 (Prunus dulcis Mill.), Myrobalan x Ferragnes, Pissardi nigra x AB3, and GF677 x Myrobalan, were used to determine resistance against root-knot nematode (RKN) (Meloidogyne spp.) using DNA markers. Parental lines and 316 F-1 plants were tested with SSR (plgms8, plgms9, and plgms19) and STS (STS-OPS14a, STS-834b) markers. It was found that plgms19 exhibited 76%, 77.01%, 73.13%, and 86.6% inheritance of resistance in the Ferragnes x Pissardi nigra, Ferragnes x Myrobalan, Ferragnes x GN22, and Nemaguard x GF677 F-1 populations, respectively. No resistance was detected in the Nemaguard x GF677 population with the plgms8 marker. Since the plgms19 and STS-834b primers were found to be effective at high ratios in determining resistance to RKN in the Nemaguard x GF677 F-1 population, the use of these markers could be included in breeding studies. It was also detected that the STS-OPS14a primer is appropriate to use for determining the sensitivity to RKN in almond rootstocks.

    Leaf Plant Nutrient Content and Sapling Growth of 'Transvalia' Peach Variety Grafted On Prunus Rootstocks
    (Springer, 2024) Ugur, Remzi; Gundesli, Muhammet Ali; Ercisli, Sezai; Ilhan, Gulce; Atli, Halit Seyfettin; Durul, Melekber Sulusoglu; Eyduran, Sadiye Peral
    In peach cultivation, there is an increasing interest in breeding rootstock suitable for intensive planting and for use in calcareous and poor soils. This study was carried out to test the performance of some promising Prunus rootstocks for 'Transvalia' peach variety. A total of 16 rootstocks obtained by interspecies hybridization from different origins were used for 'Transvalia' peach variety. Rootstock diameter, scion diameter, sapling height, rootstock scion ratio, leaf chlorophyll contents and leaf plant nutrient contents were analyzed. Results showed that the level of the majority of macro- and micro-elements was found to be sufficient. Leaf chlorophyll contents of 'Transvalia' peach cultivar grafted on stronger rootstocks such as GN-22, FG-58 and NGF-14 were found to be the highest. It has been determined that FG-16 rootstock is 40% more dwarf in terms of seedling growth strength compared to GN-22 rootstock in the Mediterranean climate zone. There were significant differences between rootstocks in terms of scion leaf chylorphyll content (SPAD values). The highest leaf chlorophyll contents were found in 'Transvalia' peach variety grafted on GN-22 (48.22), FG-58 (47.75) and NGF-14 (47.14), which are strong rootstocks. No correlation was found between growth strength and leaf plant nutrients. However, it has been determined that strong growing rootstocks can give positive results in lower quality soils.
