摘　　要：[目的]评估谷子新品种冀谷34的丰产性和稳产性。[方法]对2011-2012年国家谷子品种区域试验数据冀谷34和冀谷19的产量及主要农艺性状进行分析,利用稳产性参数评估其丰产性和稳产性。[结果]冀谷34产量高于对照冀谷19,体现了其丰产性;穗长、千粒重、公顷穗数大于冀谷19,是其产量高于对照的主要原因。回归系数结果表明,冀谷34的产量稳定性优于对照冀谷19,说明冀谷34稳产性也较好。[结论]冀谷34是一个丰产性和稳产性较好的谷子新品种,适宜在河南、河北、山东等华北夏谷区种植。[Objective] The objective of this study was to evaluate high-yield and yield-stability of millet variety Jigu 34. [Method]The main agronomic traits data of foxtail millet varieties Jigu 34 and Jigu 19 in North China summer-sowing region from 2011 to 2012 was used to reveal the changing rule of foxtail millet breeding,and their high-yield and yield-stability was evaluated by using stability parameter. [Result] The yield of Jigu 34 was higher than the control Jigu 19 because of their greater panicle length,1000-grain weight and panicle numbers per hectare. The regression coefficient results showed that the yield stability of Jigu 34 was better than Jigu 19,indicating that the stability of the Jigu34 was also better. [Conclusion] Jigu 34 was a good millet variety with high-yield and yield-stability. It was suitable to be planted in North China Summer-sowing Region of Henan,Hebei and Shandong Province.
