摘要
[目的]分析评价区试小麦品系产量的稳定性,为选育高产、稳产小麦新品种提供依据。[方法]采用变异系数法和高稳系数法对四川省小麦区试的12个品系进行丰产性、稳定性分析。[结果]参试品系XK055-3、SW22514在2种分析方法中的估计结果均表现较好;品系川04品4、04064、04062丰产性、稳产性较差;而对照品种川麦107处于中游水平,产量中等、稳定性好。[结论]西南科技大学选育XK055-3和省农科院作物所选育SW22514属高产、稳产性苗头品系。
[Objective] To analyze prolificacy and stability of wheat varieties（lines） in regional trials and provide basis for breeding of new variety. [Method] The prolificacy and stability of 12 spring varieties（lines） of regional trials of Sichuan Province were analyzed using variation coefficient method and high steady coefficient method. [Result] XK055-3 and SW22514 were high yield and stable varieties according to the two methods,while Chuan 04 pin 4,04064 and 04062 have low yield and were more easy to change with environment. The check variety Chuanmai 107 was a stable variety with a median yield level. [Conclusion] XK055-3 and SW22514 have great probability to become new high yield and stability varieties.
