Summary Twenty-four lines of common spring vetch (Vicia sativa L.), extracted at random from a collection of about 180 lines, were tested for four years at one location. Data on vegetative, reproductive and forage quality characters were recorded and analysed for three years. Appreciable total genetic variability was found in most vegetative and reproductive characters, and only very little in forage quality characters. Compared with lotal genetic variability, large environmental variability was observed in most vegetative and forage quality traits. Reproductive characters, in general, were less influenced in this respect. Forage and seed yield were negatively correlated, which was partly due to the influence of the number of days to flower. Selection for high forage yield is expected to improve by selecting plants with little branching, high % DM and longer stems with many leaves. Selection for high seed yield (number per unit area) is expected to improve with increased number of pods per stem. There were indications that crude fibre content was a better forage quality selection index than protein content, especially if combined with percentage of leaves in total DM. Selection for improved forage quality is expected to increase lodging. Some resistance to Apion sp. and Stemphyllium seedling rot was found in the material tested.
