| 摘 要： | 为全面了解云麦74品种特性和推广应用价值,根据2014~2015年云南省小麦区域试验和2016年云南省生产试验汇总资料,对云麦74的丰产性、稳产性及产量构成因素对产量的影响进行统计分析。结果表明:云麦74区试平均产量4638.22 kg/hm^2,比对照增产3.75%,具有小的变异系数和大的高稳系数,表现出良好的稳产性和适应性。穗粒数和有效穗数与产量呈极显著正相关,千粒重与产量呈负相关。穗粒数是影响云麦74产量的主要因素。综合分析,云麦74是一个具有高产潜力,稳产性强的品种,可通过适期追施拔节肥,增加穗粒数来提高产量。

| Abstract: | In order to fully understand the variety characteristics of Yunmai 74 and its application value,based on the data of Yunnan regional wheat test in 2014-2015 and Yunnan provincial production test in 2016,regression and path analysis were carried out on the effects of three factors on yield:fertility,stability and yield of Yunmai 74.The results showed that the average yield of Yunmai 74 regional test was 4638.22 kg/hm^2,which was 3.75% higher than that of the control.It had a small coefficient of variation and a high coefficient of stability,showing stability and adaptability.The number of grains per panicle and effective panicles were positively correlated with yield,while 1000-grain weight was negatively correlated with yield.The number of grains per panicle was the main factor affecting the yield of Yunmai 74.Comprehensive analysis shows that Yunmai 74 is a variety with high yield potential and strong stability.Its yield can be increased by topdressing jointing fertilizer at suitable time to increase the number of grains per ear. |
