Comparison of S2 level bean lines selected by selection breeding in terms of yield and yield components

This research was conducted to determine yield and some yield components of 22 local dry bean S2 lines. Study was established in the trial farm of the Isparta University of Applied Sciences Faculty of Agriculture during the vegetation period of 2021. Önceler 98 and Göynük 98 cultivars were used as control in the experiment. Field trials were arranged in randomized block design with 3 replications. The differences between genotypes were found significant in all the features examined in the experiment. According to the data obtained; days to flowering 42.33-58.00 days, days to pod setting 51.63-66.33 days, plant height 24.51-68.60 cm, first pod height 8.37-15.27 cm, number of pods 15.67-58.53, pod length 9.03-12.85 cm, seeds per pod 2.13-4.20, seeds per plant 5-.57-228.47, the grain yield 276.03-862.90 kg/da, hundred-grain weight 25.25-56.86 g and the protein ratio varied between 18.47-24.43%. When the results are evaluated as a whole, genotypes that are superior to the control varieties in terms of the traits examined. In terms of grain yield, ISP34, ISP23, BUR14, ISP72, ISP31, BUR20, KON17, KON16 KON5 and ISP 34 lines had higher yield values than the cultivar Önceler 98.
