| 摘 要： | 对糯玉米支链淀粉含量与主要农艺性状之间的相关性进行了分析.结果表明,支链淀粉与株高、穗位叶面积呈显著正相关,与雄穗分支数呈显著负相关;与雄穗长、穗长呈极显著正相关.在实际选择中,可以通过这几个农艺性状来选择高支链淀粉.为了进一步明确各农艺性状与支链淀粉的直接效应与间接效应,经通径分析,各农艺性状对支链淀粉的通径系数顺序为穗位叶面积＞百粒重＞株高＞穗粗＞穗长＞雄穗长＞行粒数＞茎粗＞穗行数＞穗位高＞雄穗分支数.

| Abstract: | The correlation and path analysis between amylopectin and main agronomic traits was made. The result showed that significant positive correlations were found between plant height and amylopectin content, area of spike leaf and amylopectin content. There were very significant positive correlation between tassel length and amylopectin content, ear length and amy- lopectin content. Path analysis also was carried to understand the direct effect and indirect effect between agronomic traits and amylopectin.The or... |
