Abstract：The present study aimed to evaluate the yielding ability and yield stability of Feng 03-09,a new feed barley variety.During 2011 -2013,regional trials were conducted in Dali Prefecture to assess the yielding ability,yield stability,and ecological adaptability of Feng 03-09,using the barley variety S500 as a control.The variety Feng 03 -39 was shown to surpass S500 in yielding ability and yield stability based on their differences in stability parameter,variation coefficient,and high stability coefficient.On the other side, Feng 03-39 was found to have lower yield stability than S500 according to their difference in regression coefficient.The discrepancy between the results derived from regression coefficient-based method and the other three methods might be due to that the regression coefficient-based method requires a relatively large sample size.However,the above results in general indicated that Feng 03-09 has a high yielding ability,so it can be planted for demonstration and promotion in ecologically suitable areas.
