Adaptability and stable pod per plant productivity of 20 varieties of vegetable common bean from the collection of the Vavilov Institute (VIR) were investigated. The accessions were grown on 8 selective backgrounds: four different patterns and density of planting during two years. The most adaptive accessions, i.e. most tolerant to the different density, having the stable productivity, were identified. The level of affection of accessions with bacterial diseases depending on the density of planting was also determined. The optimal pattern and sowing density had been proposed for breeding nurseries as a selective background for breeding of genotypes with stable productivity.
