    Determination of Some Characteristics of Cocksfoot (Dactylis glomerata L.) Populations Collected from Natural Areas of Eskisehir for Breeding Purposes
    (2018) Erdoğdu, İlker; Sever, A. Levent; Aygün, Celalettin; Tuna, Metin
    The aim of the research is obtaining material and information for breeding of new varieties which can beused as pasture and forage plant in Central Anatolia and resembling regions. Some of the cocksfoot (Dactylis glomerata L.)seeds, collected from natural areas in 2010-2011, and were sent with passport information to the Gene Banks in Ankara andIzmir. The rest of the seeds were grown in greenhouse and then transfered to the field. In 2012, 32 populations were identified byobserving (according to 1-9 and 1-5 scale) and measuring some characteristics. Then, mean and standard error values of theobtained data were determined. The mean values of the populations in main stem length, main stem thickness, flag leaf length,flag leaf width, number of nodes, internode length, growth pattern, rust resistance, winter resistance and tillering capacitychanged between 43.9-72.4 cm, 2.0-3.3 mm, 7.8-16.0 cm, 2.9-5.4 mm, 2.3-4.5, 7.5-16.0 cm, 6.4-8.8, 6.6-8.0, 4.7-8.3 and 5.4-8.1,respectively. The relations between the characteristics were examined by correlation analysis. Furthermore, ploidy levels ofsome single plants selected from the natural populations for breeding purposes were determined by flow cytometry analysis andall of these plants studied were found tetrapolid.

    Determination of Some Characteristics of Perennial Ryegrass (Lolium perenne L.) Populations Collected from Natural Areas of Eskisehir for Breeding Purposes
    (2018) Erdoğdu, İlker; Sever, A. Levent; Aygün, Celalettin; Tuna, Metin
    The aim of the research is obtaining material and information for breeding of new varieties which can beused as turf and pasture plant in Central Anatolia and resembling regions. Some of the perennial ryegrass (Lolium perenne L.)seeds, collected from natural areas in 2010-2011, send with passport information to the Gene Banks in Ankara and Izmir. Therest of the seeds were grown in greenhouse and then transferred into field. In 2012, 17 populations were identified by observing(according to 1-9 and 1-5 scale) and measuring some characteristics. Then, mean and standard error values of the obtained datawere determined. The mean values of the populations in main stem length, main stem thickness, flag leaf length, flag leaf width,number of nodes, internode length, growth pattern, rust resistance, winter resistance, tillering capacity, and leaf color changedbetween 30.2-48.7 cm, 1.9-2.8 mm, 5.7-10.8 cm, 3.3-4.9 mm, 2.6-3.7, 2.7-6.7 cm, 3.8-8.0, 3.8-7.9, 5.2-8.8, 5.1-9.0, and 3.9-5.0,respectively. The relations between the characteristics were examined by correlation analysis. Furthermore, ploidy levels ofsome single plants selected from the natural populations for breeding purposes were determined by flow cytometry analysis andall of these plants studied were found diploid.
