Pinto bean is planted in semi-arid regions where irrigation water is limited. Selection of drought tolerance genotypes and seed treatments may reduce water requirement of this crop in such areas. Thus, two experiments were conducted to evaluate the effects of irrigation regimes and hydropriming priming on pinto bean. In the first experiment, the effects of three irrigation regimes (Irrigation after, 50, 100 and 150 mm evaporation from pan class A as I 1 , I 2 and I 3 ) on ten pinto bean cultivars (KS-21193, KS-21191, KS-21189, E10, E9, Sadri, Talash, local masses Khomein, Eghlid and Fereidoonshahr) yield and yield components were evaluated using a split plot arrangement based on a randomized complete block design with three replications in Fereidoonshahr during 1391-1392. In the second experiment, seeds of KS-21193 were hydroprimmed for 2 hr and evaluated under three irrigation regimes (Irrigation after, 50, 100 and 150 mm evaporation from pan class A as I 1 , I 2 and I 3 ) during 1391-1392. Grain yield, yield components, plant height, grain protein were affected by irrigation regime and genotype. Grain yield, yield components, plant height expect grain protein decreased as drought level increased. The highest grain yield was produced by genotype KS-21191 (2319 kg/ha while the lowest was noted in Eghlid (1700 kg/ha). The highest yield was obtained under I 1 while the lowest yield was obtained under I 3 . However, there was interaction between irrigation regime and genotype on grain yield. The highest seed yield was recorded in KS2191 under I 1 while the lowest was noted in Sadri under I 3 . The results showed that selection of more drought tolerance genotype in pinto bean under stress and non-stress conditions. Hydropriming effect on most of measured traits expect biological yield and grain protein no significant.
