The project of mutation breeding in barley (first report)

Barley is a second main crop with the production of 7 million tons per year and 3,5 million hectare cultivation area in Turkey. Because of wateer deficiency, cereals cultivated in Central Anatolian region. Barley is well adapted to dry farming system besides it is basic food for animal husbandry and main raw material for brewery industry. the main problems in barley production are drought disease epidemic and increasing salinity gradually. Main purposes of our project is to increase resistance and tolerence to this stress factors. In order to reach to our aim we have been using mutation breeding techniques and conventional breeding methods. This Project has been started with irradiation of barley seeds with different gamma ray doses. After that resistant and tolerant mutant has been selected most of these mutanys have resistance and tolerance to different disease and stress conditions. During the selection procedure, hydroponics and tissue culture techniques have been applied to improve the selection efficiency. Up to now, promising barley mutant lines 71 that have earliness (30 days) than parents and because of that reason that escape from drought period. Disease tests of our mutant lines have been conducted under controlled conditions and tolerant lines have been determined under the high the high epidemic conditions. Salt tolerance studies have been applied under hydroponics conditions and salt tolerant mutant have been determined under 180-200mMolNaCl concentration. All mutant lines are carried out to preliminary yield trials for their evaluation
