Yield and yield components is one of the key objectives of the legume breeding program worldwide. Information on these traits is required for the selection of desirable types and efficient utilization of the genetic diversity in dry bean improvement program. Local landraces of dry beans grown over long time period are more resistant to low input growing conditions its genetic and morphologic properties and quality is more acceptable by the growers. From this perspective, 83 dry bean landraces were collected from different bean growing areas of Western Anatolia Region of Turkey in 2015-2016. The dry bean landraces were grown on the experimental farm of Abant Izzet Baysal University, Bolu during 2016 growing season. A single plant from each dry bean landrace was selected according to morphological characterization results and weighted scaling method, and twenty (8 climber and 12 bush types) dry bean lines were accepted as promising. In the present study, yield and yield components of 12 dry bean lines and 2 commercial cultivars were compared in Bolu province under western black sea ecological condition of Turkey. The experiment was arranged in a Randomized Block Design with three replicates in 2017 growing season on the experimental farm of Abant Izzet Baysal University. Emergence percentage (69.50-96.00%), days to flowering 50% (48.00-52.00 days), days to maturity (86.00-107.33 days), plant height (37.20-58.30 cm), height to first pod (12.50-19.00 cm), number of branches per plant (6.25-8.25), number of pods per plant (16.96-41.50 pods), seeds per pod (4.00-6.40 seeds), seed yield per plant (25.41-96.83 g plant-1) and 100 seeds weight (29.82-55.35 g) were determined according to IPGRI and EU-CPVO criteria. As a result, lines ÇNK-2, ÇNK-4, YLV-28, YLV-32 and BLCK-7 had superior with respect to yield and yield components and hence selected advanced promising lines will be transferred to regional yield trials required for the official procedures of cultivar registration.
