摘要： The advantages and disadvantages of alfalfa varieties affected the establishment and production performance of alfalfa. In order to screen out the excellent varieties for experimental research and production, a new alfalfa (Medicago sativa L.) variety Zhongtian No. 1 (ZT1) was developed by space mutation with microgravity, high vacuum and strong cosmic radiation. Four different alfalfa varieties were used as control. Design of experiment was randomized complete block and the comparison was made for the productivity and quality of ZT1. The experiment was conducted at two field locations on the Loess Plateau in north-central China. The basic characteristics of ZT1 were high quality and high yield, in accordance with high multifoliaolate rate and high nutrition. The leaflet number of ZT1 was 5 mainly, and the multifoliaolate rate was 41.5%. Furthermore, the hay yield of ZT1 was 15,508.4 kg.ha(-1), which was 12.69% higher than control varieties. The CP content was 20.08%, which was 2.97% higher than control varieties, and AAs content was 12.32%, which was 1.57% higher than controls. The results revealed that ZT1 was valuable for improving the yield and quality of alfalfa, which owned the resources advantages in alfalfa industrialization, and had wide application prospect.
