Abstract

Improved lines each of common vetch (Vicia sativa), woolly-pod vetch (V. villosa) and narbon vetch (V. narbonensis) obtained from the International Center for Agricultural Research in the Dry Areas (ICARDA) were evaluated for seed and forage production at 4 sites in the alpine grassland of China. Annual mean rainfall and temperature ranges were 253—661 mm and 1.4—3.6ºC, respectively. Differences in productivity were found between the 3 vetch species and between the lines within each species. Nine common vetch and 4 narbon vetch lines produced seeds. Common vetch lines 2505, 2556, 2560 and 2566 and narbon vetch line 2561 were identified as having the necessary potential for seed and
