Seed loss at harvesting time is one of the factors reducing seed yield in at farms. This study was carried out within a Research Farm in Karaj to evaluate and select a proper pinto bean line for mechanized harvesting at two moisture contents during harvesting and their effect on seed yield and yield loss among three lines of pinto bean. The experiment was split-plot based on randomized complete block design with three replications. The main plot included pinto bean lines with three levels (KID-31, 118116 and Cos16) and the sub plot included seed moisture content during harvesting with two levels (%17±2 and %12±2). These lines were evaluated and compared for seed loss at farm. Results showed that there was a significant difference between lines in seed yield. The highest amount of seed yield belonged to Cos16 with 1612.9 kg.ha-1. Also this line had the lowest loss during harvesting when the moisture content of seeds was %12±2. There was a positive correlation between seeds moisture content and amount of seed loss showing the best moisture content for mechanized harvesting as %12±2. In addition, there were no significant differences among lines for this trait.
