Abstract: Fall dormancy (FD) in alfalfa is related to regrowth, yield and plant height in autumn. The objectives of this research
were to evaluate variability for agronomical traits among 42 alfalfa varieties with fall dormancy classes ranging from 2 to 9 in
Zhengzhou, China. The results were as follows: (1) The dry matter yields (DM) of 42 varieties in 2004 and 2005 were higher than
those in 2002, and the yield in 2002 was higher than that in 2003, due to the low temperature and high rainfall in 2003; (2) DM
yields of fall dormant and semi-fall dormant alfalfa were higher than those of non-fall dormant alfalfa; (3) Cutting times had a
significant effect on DM herbage yield, with the highest yield in the f
