小麦新品种郑麦1860高产稳产特性分析

Analysis on Characteristics of High and Stable Yield of New Wheat Variety‘Zhengmai 1860’

依据2015-2018年度国家冬小麦黄淮南片水地组区域试验和生产试验及2015-2016年度国家小麦产业技术体系品种大区展示试验数据,分析了郑麦1860高产稳产特性。结果表明,两年区域试验郑麦1860平均产量8457.0 kg·hm^(-2),比对照周麦18增产5.19%,差异极显著;生产试验平均产量7356.0 kg·hm^(-2),比对照周麦18增产5.21%,增产点率100%;在国家小麦产业技术体系设置的5省13个试验点中,平均产量8296.7 kg·hm^(-2),排第一位。区域试验和生产试验平均高稳系数(85.49%)比对照约高5个百分点。表明小麦品种郑麦1860高产稳产性突出。同时,以2017-2018年国家冬小麦黄淮南片水地组生产试验数据为依据,进行了郑麦1860的产量三要素与产量相关性分析,结果表明,有效穗数与产量呈极显著正相关,生产上可适当增加群体提高有效穗数来进一步发掘郑麦1860的高产潜力。

Based on the datum from area test of water-ground group and production test in south Huanghuai region of National Winter Wheat Growing Area(NWWGA)during 2015 to 2018 and the display test datum of variety in large area of National Wheat Industry Technical System during 2015 to 2016,the characteristics of high and stable yield of Zhengmai 1860 were analyzed.The results showed that the average yield of Zhengmai 1860 in 2-year regional experiment was 8457.0 kg·hm^(-2),which was 5.19%higher than that of the control Zhoumai 18,and the difference was very significant.In the production test,the average yield was 7356.0 kg·hm^(-2),which was increased by 5.21%and 100%compared with the control Zhoumai 18.Among the 13 experimental points in 5 provinces set up by the National Wheat Industrial Technology System,the average yield was 8296.7 kg·hm^(-2),ranking the first.And,The average high stability coefficient of regional test and production test(85.49%)was about 5 percentage points higher than that of the control,which implied that the wheat variety Zhengmai 1860 had outstanding high and stable yield.Meanwhile,based on the datum from area test of water-ground group in south Huanghuai region of NWWGA druing 2017 to 2018,the correlation analysis of yield and its 3 factors of Zhengmai 1860 was also conducted.The results showed that there was a significant positive correlation between the number of effective panicles and yield and the potential of high yield of Zhengmai 1860 could be further explored by appropriately increasing the population and increasing the number of effective panicles in terms of production.
