摘要: 为探明玉米品种的主要农艺性状对产量的影响程度,用灰色关联度的分析方法,对2013年44个玉米品种的主要农艺性状与产量进行关联分析。结果表明:在参试品种中穗粗(0.9874)、叶片数(0.9645)、穗长(0.9488)、株高(0.9465)、穗行数(0.9429)、百粒重(0.9244)、穗位(0.9088)、出籽率(0.8882)、秃尖(0.7381)等性状影响着玉米产量,其中,影响最大的主要性状是玉米的穗粗、叶片数和穗长,其次是株高和穗行数,千粒重对产量的影响相对居中,相比较之下,穗位、出籽率和秃尖对产量的影响最小。

Abstract: To investigate the influence of main agronomic traits of different maize varieties on yield, the author adopted grey correlation analysis method to analyze the correlation of the main agronomic traits and yield of 44 maize varieties in 2013. The results indicated that traits such as ear diameter (0.9874), leaf number (0.9645), ear length (0.9488), plant height (0.9465), rows per pear (0.9429), 100-kernel weight (0.9244), ear height (0.9088), shelling percentage (0.8882), and barren tip (0.7381) affected the yield of maize. Among these agronomic traits, ear diameter, leaf number and ear length had the maximum influence on maize yield, followed by the plant height, ear rows and 100-kernel weight, and by comparison, ear position, shelling percentage and barren tip had the minimum influence.
