In this study yield and seed yield components of twenty nine lentil (Lens culinaris Medik) genotypes were compared in a used Pilot project used augmented as a randomized complete block design with three replications, was carried out in Ardabil Agricultural Research Station, in 2010. traits Average based on 10 plant competitors who were randomly selected and analyzed following measurements: green Percent, days to flowering time, number of hooks, hook size, grain yield per unit area, days to reach a plant height, Height, lowest pod, harvest index, number of filled pods per plant, empty pods per plant, seed number per 100 pods, number of primary branches per plant, number of secondary branches per plant, biomass and seed weight. Results showed highly significant correlation between grain yield and green Percent, plant height, number of filled pods per plant, biological yield, plant height, pod number per plant, seed number per 100 pods, biomass and seed weight. Stepwise regression analysis of grain yield with other traits showed that the increase in biomass and reduce the number of secondary branches will have a positive effect on yield.
