Abstract: To screen legume forage varieties that were suitable for the development of grassland ecological animal husbandry in Guizhou Province, twenty-six tested materials of Cajanus cajan were compared by the random block method. The results showed as follows①All tested materials could normally blossom and pod bearing and complete the whole growth cycle. The growth period was 168~226 days, and the plant height at maturity was 124~286 cm. ②The highest yield of fresh grass was 201510, 201505, 201502, 201508 and 201516 in 65.41~67.18 t/hm². ③The highest seed yield of 3 252.45~4 221.58 kg/hm² was 201516, yellow Cajanus cajan, 201511, 201507 and 201517. ④Five varieties suitable for forage and seed production utilization were proposed respectively through the screening test for introduction, providing excellent varieties for promotion and utilization of different uses in production.
