Photoperiodic response of a large number of lentils (Lens culinaris Med.) genotypes from diverse geographical regions was studied in pot culture in a plastic house. The plants were exposed to three photoperiods: "short day" (8 hrs light period), "normal day" (13.5-14.4 hrs light period in summer, 1978, and 9.5-13.5 hrs light period in winter, 1978/79), and "long day" (15 hrs light period in summer, 1978 and 16 hrs in winter, 1978/79). All genotypes behaved as "long day" plants, although they differed in the length of their critical photoperiod and quantitative response to "long day". The genotypes originating from lower latitudes (Ethiopia, Sudan, Egypt, and India) had a shorter critical day length than the genotypes from higher latitudes
