To accelerate the application of the core collection of adzuki bean in breeding, we investigate the adaptability of these germplasm under different environments at continuous years. The results show that all the core collections are erect and can be harvested in Nanning, while only 64.2%88 of them are erect in Tangshan and 25 germplasm even can not mature. The agronomic traits were significantly different between eco-environments, and in Nanning, there were also significantly variations from different years, indicating the sensitivity of adzuki bean to light or temperature and other environmental factors. The growth periods of the core collections were significantly shorter in Nanning than in Tangshan, however, the number of pods per plant and 100-seed-weight were much lower. The present result also indicated that breeding for new variety with wide adaptability was possible. Based on the agronomic traits, 8 and tenin total 16 elite germplasm, were selected to bethat can be used directly in breeding or production at Nanning and Tangshan, respectively, were selected.
