| 摘 要： | 应用灰色关联度法对干旱地区7个玉米品种的农艺性状及产量的关联度进行分析,判断各性状对产量的影响程度,从而确定干旱地区玉米选育目标及制定相应栽培技术措施。结果表明,玉米产量与各产量性状的关联度表现为:株高0.595 93、穗位高0.571 86、穗长0.809 2、穗粗0.623 93、秃顶长0.667 3、穗行数0.661 57、行粒数0.796 67、千粒重0.615 08,关联序为穗长行粒数秃顶长穗行数穗粗千粒重株高穗位高。穗长和行粒数是影响玉米产量的主要因素。

| Abstract: | The relationship between agronomic characters and yield of 7 maize varieties were analyzed by gray correlated degree method to study effect of different yield characters on yield for drawing up the breeding target and corresponding cultivation technique.The results showed that the correlated degree between yield and plant height,ear height,ear length,ear diameter,barren tip length,rows per ear,grains per row and 1 000-grain weight was 0.595 93,0.571 86,0.809 2,0.623 93,0.667 3,0.661 57,0.796 67 and 0.615 08... |
