摘要：

为了全面了解菏麦22的产量特性,利用2015—2018年黄淮冬麦区北片水地组区域试验和生产试验数据,采用方差分析、变异系数、高稳系数、增产点比例和适应度等方法,对菏麦22的丰产性、稳产性和广适性进行了系统分析和综合评价。结果表明,2015—2016年菏麦22比对照品种济麦22略减产,减产不显著,2016—2018年两年菏麦22比对照品种济麦22均增产且增产显著,具有较好的丰产性;2015—2018年菏麦22的产量变异系数(CV)和高稳系数(HSC)均居参试品种的前列,具有较好的稳产性和丰产性;菏麦22试验3年的平均适应度与对照品种良星99、济麦22的平均适应度相当。除2015—2016年菏麦22的增产点率较低外,2016—2018年两年的增产点率分别达到89.5%、91.7%,表明在多环境下具有较好的适应性。综合分析表明,菏麦22集合了高产、稳产、广适、多抗、优质等优良性状,在黄淮冬麦区北片生态区域有较高的推广利用潜力。

Abstract:

To identify the yield characteristics of Hemai 22, this study used the data of regional test and production test of water area group in the north of Huang-huai winter wheat area from 2015 to 2018, and the high yield, stability and wide adaptability of Hemai 22 were systematically analyzed and comprehensively evaluated by variance analysis, coefficient of variation, high stability coefficient, rate of yield-increasing point and degree of adaption. The results showed that in 2015 to 2016, the yield of Hemai 22 was slightly lower than that of the control variety Jimai 22, and the yield reduction was not significant. In 2016 to 2018, the yield of Hemai 22 was significantly higher than that of the control variety Jimai 22, showing better production performance. In 2015 to 2018,the yield coefficient of variation and high temperature coefficient of Hemai 22 were in the forefront of the tested varieties, and had good stability and high yield. The average fitness of Hemai 22 in 3 years was equivalent to that of Liangxing 99 and Jimai 22. Except for the low yield point rate of Hemai 22 in 2015 to 2016, the yield increase point rates in 2016 to 2018 reached 89.5% and 91.7%, respectively, indicating that it had good adaptability in multiple environments. The comprehensive analysis showed that Hemai 22 had high yield, stable yield, wide adaptability, multi-resistance, high quality and other excellent traits, and had high promotion and utilization potential in the northern ecological area of Huang-huai winter wheat region.
