Determination of Some Characteristics of Cocksfoot (Dactylis glomerata L.) Populations Collected from Natural Areas of Eskisehir for Breeding Purposes
Öz
ABSTRACT: The aim of
the research is obtaining material and information for breeding of new
varieties which can be used 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
and Izmir. The rest of the seeds were grown in greenhouse and then transfered
to the field. In 2012, 32 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 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
capacity changed 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 of
some single plants selected from the natural populations for breeding purposes
were determined by flow cytometry analysis and all of these plants studied were
found tetrapolid.
