Known as herbicide tolerant lines and commonly cultivated winter lentil varieties in Turkey were hybridized reciprocally. The aim of this study was to shorten time between lentil generations by increasing light exposure period and luminescence intensity under controlled conditions to increase genetic progress of hybrid populations. One generation progress can be achieved in a year by conventional lentil breeding studies in field conditions. In this study, by prolonging the light exposure time and early seed harvesting, the populations were progressed one generation within 60 days. Morphological and physiological changes in plants were observed by keeping lighting intensity and duration different in greenhouse and controlled growth room. In this study, speed breeding techniques were used in lentils. By integrating these techniques into classical breeding studies, lentil varieties with the desired characteristics will be developed in a shorter period of time.
