| 摘 要： | 利用2011—2013年大理州大麦品种区域试验结果,以S500为对照,通过比较产量增幅、稳定性参数、变异系数、回归系数和高稳系数分析饲料大麦新品种凤03-39的产量及对环境适应的稳定性。稳定性参数法、变异系数法和高稳系数法分析均显示,与S500相比,凤03-39具有较高的丰产性和稳产性;而回归系数法得出凤03-39较S500稳定性较差,可能因为回归系数法对样本容量要求较高,导致其分析结果与其它方法所得结果出现差异,但总体趋势表明凤03-39具有高产性,这有利于该品种在适宜区进行示范推广。

Analysis of the High Yielding Ability and Yield Stability of Feng 03-09,a New Feed Barley Variety |

| 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. |
