Phaseolus germplasm collection has a considerable potential value which can be widely used in breeding work as well as for direct use by farmers. The objective of the present research was to make morphological, agro-biological and agronomic characteristics of local and foreign accessions in order to select those with desirable traits. The study was carried out during the period 2021-2023 with 35 accessions of common bean (Ph. vulgaris L.). The accessions were with maturity from 84 to 98, with mean value of 88.5 days. Six accessions were the earliest with 84 days, while the latest were with maturation of 98 days. Two accessions showed higher grain yield from one plant (C1E0076, 93201018) with 17.8 and 18.9 g, respectively. Bigger variation was registered in weight of plant without pods and weight of plant, as well as number of pods and weight of seeds per one plant with coefficient of variation (CV%) 94.8, 57.0, 51.2 and 44.5%, respectively. The promising accessions will be selected as the most perspective with a view of their future utilization in the breeding process.
