国审小麦新品种徐麦368高产稳产特性分析

Analysis on Characteristics of High and Stable Yield of New State-authorized Wheat Variety Xumai 368

根据2017—2020年度国家小麦联合体黄淮南片水地组试验汇总材料,分析徐麦368的丰产性、稳产性和适应性,并探究其产量与产量构成因素之间的相关关系。结果表明,徐麦368具有较好的丰产性,各年度产量水平均极显著高于对照品种。该品种适应性较强,3个年度其增产点率分别为100%、70.8%和90.9%。同时,表现出较好的稳产性,其高稳系数为82.1%~95.0%,比对照高1.2%~11.3%。徐麦368的产量与有效穗数和千粒质量均呈极显著正相关。徐麦368对叶锈病抗性较好,具有较好的抗倒伏能力。

Based on the summary data of the national Huanghuai Wheat Area(south region)test in 2017-2020,the analysis on characteristics of high yield,yield stability and wide adaptatbility of Xumai 368 were reported,as well as the correlation analysis between yield and its components.Results showed that Xumai 368 had outstanding characteristics of high yield,and its grain yield was extremely significant higher than that of the control Zhoumai 18 in each test year.The characteristics of wide adaptability was found in Xumai 368,and the rate of test site with yield increase reached 100%,70.8%and 90.9%,respectively in three test year.The high stability coefficient was 82.1%-95.0%in Xumai 368,which was 1.2%-11.3%higher than that of the control Zhoumai 18,indicating that this wheat variety had excellent high and stable yield.There were extremely significant positive correlation between the effective panicle number,1000-grains weight and grain yield.Xumai 368 had strong resistance to leaf rust and lodging.
