| 摘 要： | 为研究在晋南复播条件下油葵杂交种农艺性状与产量的关系及相关程度,为新品种选育提供可借鉴的理论支持,对15个油葵杂交种10个农艺性状与产量的相关关系及通径进行分析。结果表明:株高、茎粗、单盘粒数、单盘粒重与产量呈显著或极显著正相关,倒伏率与产量呈显著负相关;单盘粒数和单盘粒重主要通过直接效应影响产量,茎粗主要通过间接效应影响产量,株高和倒伏率通过综合效应影响产量。进一步的研究结果显示,随株高和单盘粒数的增加,产量呈先上升后缓慢下降的趋势,当株高172.1~176.8cm,单盘粒数1352~1428粒时,产量达到最大值。故此认为,在新品种选育中应通过对单盘粒重、单盘粒数等一些直观的性状的选育达到选育高产的目的。

| Abstract: | In order to sdudy the correlation between agronomic and yield of summer oil-sunflower, the agronomic trait and yield of 15 hybrids grown in the south part of Shanxi Province, China in 2009 were investigated to conduct correlation analysis and path analysis. It was found that the plant height, the stem diameter, the number of single disc seed, and the single disc weigh showed a significant or extremely significant correlation with the yield, while the lodging percentage showed a significant negative correlat... |
