Pulses crops with nitrogen fixation ability have a special place in the crop rotation. In order to comparethe agronomic characteristics of five promising lines of pinto beans with Sadri and local Khomeincultivars as control a study was conducted at 2011- 2012 cropping seasons, in three cities ofFereidoonshahr, Dehaghane and Semirom in Isfahan Province. Randomized complete block design withfour replications was used for the study. In Fereidoonshahr area, yields of KS21191, E9, and E10 hopefullines were respectively, 3035, 3412 and 3455 kg ha-1, without significantly different from Sadri controlcultivar, but were respectively 37, 21.8 and 20.3% less than Khomein local varieties. In Dehaghane area,yields of all hopeful lines were significantly less than both control cultivars. In Semirom region, hopefullines of E9 and E10, respectively, with yields of 2900 and 2720 kg ha-1 had equivalent yield with twocontrol varieties. Number of pods per plant and seeds per pod were the two major components thatexplain a significant part of the difference between the genotypes. Trend of harvest index change weresimilar in the two regions Dehaghane and Fereidoonshahr and Khomein local cultivars, respectively with42.8 and 38.8 HI percent, had the highest HI values. In Semirom region, harvest index for Sadri andKhomein cultivars and lines E9 and E10, were 37.1, 36.8, 35.8 and 36.5 percent respectively. Accordingto the results of this study, yield of E9 and E10 lines, in both Fereidoonshahr and Semirom regions, andyield of KS21191 line, only in Fereidoonshahr can be equal with the yield of control cultivar. Thepromising lines of this study were not appropriate for the Semirom area.
