宁麦28丰产性·稳产性及适应性分析

Analysis of High Yield,Stable Yield and Adaptability of Wheat Variety Ningmai 28

[目的]分析小麦品种宁麦28的丰产性、稳产性和适应性,为其推广应用提供参考。[方法]采用2015—2018年江苏省淮南片小麦区域试验和生产试验以及2016—2019年长江中下游联合体区域试验和生产试验的资料,通过平均产量、变异系数、高稳系数和适应度分别对宁麦28和对照品种扬麦20的丰产性、稳产性和适应性进行比较。[结果]宁麦28产量较对照扬麦20增产极显著,6组88个点次的平均产量为6676.6 kg/hm^2;产量变异系数与扬麦20相仿,但高稳系数和适应度远远高于扬麦20。[结论]宁麦28丰产性突出、稳产性好、适应性广,在长江中下游地区具有较广阔的应用前景。

[Objective]In order to provide the guidance for its application in the large areas,the high yield,stable yield and adaptability of wheat variety Ningmai 28 were analyzed.[Method]Based on the data of regional test and production test of Huainan area in Jiangsu from^2015 to 2018,and regional test and production test of the association in the mid-lower reaches of the Yangtze River from 2016 to 2019,the yield,stability and adaptability of Ningmai 28 and Yangmai 20(CK)were compared by grain yield,coefficient of variation,high stability coefficient and adaptability,respectively.[Result]The yield of Ningmai 28 was significantly higher than that of the check variety Yangmai 20,and the average yield of Ningmai 28 at 88 test locations was 6676.6 kg/hm^2.The coefficient of variation of the yield of Ningmai 28 was similar to that of the Yangmai 20,but the high stability coefficient and the adaptability were much higher than that of the Yangmai 20.[Conclusion]Ningmai 28 with high yield,good stability and broad adaptability has a wide application prospect in the mid-lower reaches of the Yangtze River.
