Analysis of Characteristics for Six Alfalfa Cultivars

YAN Xu dong,ZHU Zhi ming,LI Gui rong,ZHAI Yu zhu,KONG De ping,XU Yu peng (Cangzhou Academy of Agricultural & Forestry Sciences, Hebei,061001, China)  
Under the natural condition, six alfalfa varieties of Gannong No.1, Hetian, Cangzhou, Anstar, Kitawakaba and Tachiwakaba from domestic and aboard were identified on analysis of characteristics and adaptability through 4 years (1997~2000) in low plain area of seashore of Hebei. The results of variance analysis showed that Anstar and Gannong No.1 had the characteristics of good stability, high yield potential, strong regeneration and so on, which were favorable in planting on large areas. The variety of Kitawakaba from Japan was susceptible to water, which was favorable in planting on those plots having the condition of irrigation. In addition, Anstar alfalfa and Kitawakaba et al. were lodging resistant and had good orthotropism, which were suitable for mechanized harvesting. Endemic variety Cangzhou alfalfa was oppressed at hay yield, regeneration and orthotropism.
