Phaseolus vulgaris L. is a major source of protein in the world and Africa. Seedling vigour is an important aspect in the early life of common bean. Two experiments were carried out to examine variations in seedling vigour and the effectiveness of emergence (E %), emergence index (EI), emergence rate index (ERI), growth rate (GR) and relative growth rate (RGR) among 5 Phaseolus accessions. For each experiment, accessions were laid out in randomized complete block design with three replications. Significant differences were observed for E%, ERI, GR and RGR in accessions, environment and the interaction between accessions and environment, suggesting that selection for further improvement is possible due to the large variability present. Accession 2 had the highest E%, all accessions had about the same ERI value. Accession1 had the highest GR while accession 4 recorded the lowest GR.Accessions 2 and 5 had highest values for RGR, while accession 4 maintained the lowest RGR value. Genotypic and phenotypic variances were generally high for E%. High heritability values for E%, EI and RGR were observed. The results of the study indicates the potential of Phaseolus cultivation in the Sudan Savanna and a good establishment of the plants.
