稻田春播杂交玉米产量与主要农艺性状的相关及通径分析OA北大核心CSTPCD
Correlation and Path Analysis between Main Economical Characters and Yield of Hybrid Corn Sowed in Spring and Cultivated in Rice Field
[目的]对稻田春播杂交玉米产量与主要农艺性状进行相关及通径分析.[方法]以湘南丘陵山区稻田春播的15个杂交玉米品种为材料,采用相关分析和通径分析方法分析了玉米品种8个主要农艺性状与产量的相互关系.[结果]株高、穗位高、行粒数与产量呈极显著正相关;主要农艺性状对产量的直接通径系数的大小依次为:行粒数>百粒重>穗行数>秃顶长>株高>穗长>穗位高>穗粗.行粒数对玉米产量的影响主要取决于直接作用;株高、穗位高、穗…查看全部>>
