Common vetch (Vicia sativa L), hairy vetch (Vicia villosa Roth), and Pannonian vetch (Vicia pannonica Crantz) are the most often grown varieties in the production area of Serbia. The most important problem in the production of vetch seed is lodging. Yield and seed quality in lodged crops can be signifi cantly reduced. Therefore, it is very important to accurately estimate the quality, and viability of produced seed. Common vetch, hairy vetch and Pannonian vetch were submitted to vigor testing using standard laboratory test, cold test, Hiltner test, and three variants of accelerated aging tests (39 deg C,72 h; 39 deg C, 96 h; 45 deg C, 48 h). When the standard laboratory test was applied, the common vetch achieved the highest seed germination value of 90%, while decreased rate of seed germination was due to unfavorable conditions applied in vigor tests. Above ground seedling growth parameters were the lowest when Hiltner test was applied. Length and mass of the root system were the lowest when accelerated aging test was applied. Hairy vetch obtained the lowest values for all tested parameters when Hiltner test was applied. Application of different variants of accelerated aging tests indicated that tested parameters were not dependent on the applied temperature, while reduction in legumes vigor was under the infl uence of temperature duration.
