摘　　要：以2010-2013年湖北省小麦(Triticum aestivum L.)区域试验结果为依据,利用产量变异系数和高稳系数法对漯麦6010稳产性和产量构成因素进行相关性分析,并对产量构成因素进行通径分析。结果表明,产量结构三要素中,以穗粒数和千粒重最为稳定,其变异系数较小;穗数与产量的相关性最大,千粒重次之,穗粒数与产量呈负相关;穗数与穗粒数呈正相关,千粒重与穗数、穗粒数均呈负相关;通径分析结果表明,穗数、千粒重、穗粒数与产量的相关系数分别为0.305 3、0.268 2、-0.103 2,且直接通径穗粒数最大,千粒重次之。For a more comprehensive understanding of the characteristics of wheat production with new wheat varieties Luomai 6010,with 2010-2013 of Wheat Regional Test in Hubei Province Based on the results,through the coefficient of variation of output and high stability coefficient method on Luomai 6010 high yield stability and adaptability. The results show that,Yield structure of three elements,with the most stable as the number of grains per spike and 1 000 grain weight,the coefficient of variation is small;panicle number and yield the maximum correlation （0.305 3）,1 000 grain weight （0.268 2）,the second was negatively related to the number of grains per spike and grain yield （-0.103 2）;related spike number and grain number was positive（0.489 7）,a negative correlation between 1 000 grain weight and panicle number,grain number per spike were （-0.501 1, -0.708 6）;through the path analysis ,number of spike, 1 000 grain weight ,grain number per spike and yield related respective- ly;0.305 3,0.268 2,-0.103 2,and direct path grain number per spike,1 000 grain weight（maximum 0.596 9） times （0.572 6）.
