The phenology and agronomic characteristics of seven accessions of common vetch (Vicia sativa L.) were assessed over two years and contrasting sites through making the following notations and measurements: flowering and maturing dates, seed and biological yield, pod number per plant, seed number per pod, seed weight, and percent of shattering. Analysis of variance showed a significant effect of the environment (sites, year and site x year interaction) on all the agronomic and phonologic traits except the number of pods/plant. Significant variation was found between accessions for earliness, seed weight and number, and seed yield. All accessions flowered earlier in the sub-humid site while seed yield, seed number and weight were higher in the semi-arid site. Positive and significant correlations were found between seed yield and seed number (r equal to 0.47, P less than 0.04, n equal to 19), flower number and seed weight (r equal to 0.88; P less than 0.001) and flower number and seed yield (r equal to 0.93; P less than 0.0001). The highest average seed yield was recorded for INRAT 303, a local variety (1232 kg ha-1), while the lowest value was recorded for accession VS7 from Syria (888 kg ha-1). Based on their earliness and lower shattering rate, accessions VS8 and VS15 originating from Cyprus and Afghanis - tan respectively, were selected as promising grain yielding lines
