Loss of viability and seeds vigour influences the nutritional characteristics and reduce their agricultural use. The aim of this research was the testing of seed viability, vigour and germination ability respectively, in the seeds of common bean landraces stored in Gene Bank of Kosovo for Plant Resources, stored in long-term storage conditions (-18 to – 25°C). The experiment was conducted in the laboratory. For this purpose were used seeds of 10 accessions. The experimental design was random complete block with three replications: 10 landraces x 3 replications x 2 parameters = 60 measurements. For each accession, 45 seeds (15 seeds per replication) were tested. Seed viability test was carried out according to ISTA (2003) rules. Seeds vigour was estimated after 4 days, while germination ability was evaluated 8 days after testing. Data was subjected to Analysis of Variance (ANOVA) and means separated by Least Significant Difference (LSD) at P <0.05, P <0.01. The research results show significant differences among common bean landraces for seed vigour and germination ability on the level P0.01 and P0.05.
