优质强筋小麦云麦80高产稳产及适应性分析

Analysis on High and Stable Yield and Adaptability of High Quality and Strong Gluten Wheat Yunmai 80

为给优质强筋小麦云麦80的推广提供依据,以2015—2017年度云南省田麦品种区域试验汇总资料为依据,利用产量、变异系数、高稳系数和回归系数,对云麦80的高产、稳产性进行分析。结果表明,云麦80两年区试产量分别为6593.03和6082.14 kg/hm^(2),较CK增产6.64%和5.93%,高稳系数排名分别为第1、4,回归系数分别为0.672和0.880,对环境不敏感,同时品质达到强筋标准,说明云麦80是一个丰产稳产性和适应性好的优质小麦新品种,适宜在云南省大面积种植。

In order to provide the basis for the promotion of high-quality and strong-gluten wheat Yunmai 80,this study analyzed the high and stable yield of Yunmai 80 through yield,coefficient of variation,high stability coefficient and regression coefficient based on the summary data from 2015 to 2017 in the regional trials of Wheat Varieties in Yunnan Province.The results showed that the yield of Yunmai 80 in the two-year regional trials were 6593.03 kg/hm^(2) and 6082.14 kg/hm^(2) respectively,which increased by 6.64% and 5.93% comparing with CK.The high stability coefficient ranked the first and the fourth respectively,and the regression coefficient was 0.672 and 0.880 respectively.It was not sensitive to the environment,and the quality reached the standard of strong-gluten.It concluded that Yunmai 80 was a new wheat variety with high yield,stable yield and good adaptability,which was suitable for planting in large area in Yunnan Province.
