摘要
为浩麦1号更好地在生产上推广应用提供依据,利用2010-2011年与2011-2012年国家冬小麦品种区域试验和2012-2013年度国家冬小麦品种生产试验数据,对该品种的产量构成因素进行分析。结果表明:浩麦1号的平均穗数505.13万/hm^2,平均穗粒数39.31粒,平均穗粒重1.56g,平均千粒重39.78g。经相关分析,穗数、穗粒数、穗粒重和千粒重均与籽粒产量呈正相关,穗粒数>千粒重>穗数>穗粒重;经通径分析,穗粒数对产量的作用最大(Py=0.531),其次是穗数(Py=0.471),穗粒重的作用最小(Py=0.094)。浩麦1号的高产栽培技术应在保证足够穗数和穗粒重稳定的基础上,主攻穗粒数,同时兼顾粒重。
In order to provide references for generalization and application of Haomai 1in production,the yield components were analyzed based on data of winter wheat cultivar Haomai 1from national regional trials in 2010-2011 and 2011-2012,and national production tests in 2012-2013.Results：Spike number,kernels per spike,grain weight per spike and thousand kernel weight was respectively 5051.3thousand spikes/hm^2,39.31 grains,1.56 g and 39.78 g.Correlation analysis showed that grain yield positively correlated with spike number,kernels per spike,grain weight per spike and thousand kernel weight,kernels per spike〉thousand kernel weight〉spike number〉grain weight per spike;Path analysis showed that kernels per spike contributed the most to yield（Py=0.531）,followed by spike number（Py=0.471）and grain weight per spike（Py=0.094）.On the basis of ensuring sufficient spike number and stable kernel weight per spike,kernels per spike should be paid more attention to,and grain weight per spike should be given consideration to either.
