摘　　要：通过4×4完全双列杂交,对苎麻杂交当代种子进行含油量配合力分析,研究表明:苎麻种子含油量遗传存在母性效应,同时也与父本有关,受加性和非加性效应控制,其狭义遗传力为51.32％;通过对38份材料的农艺性状和经济性状的相关分析,发现有效茎数与原麻产量和种子产量的偏相关系数分别达到了极显著和显著性水平;含油量与雄花节数呈极显著负相关,与雌雄同花枝花节数显著负相关。It was shown that ramie seed oil contents were affected by its femle parents much more than its male parent in F1 population of 4 × 4complete diallel cross and were controlled by addictive and noon -addictive effects. The HN2was 51.32%. The simple correlations between oil content, male floral node number and androgynous node number were negatively significant.
