摘　　要：应用灰色关联度对94份苎麻种质的农艺性状进行了关联性分析和综合评价。结果表明:苎麻地上部生物量与株高、茎粗、鲜皮厚度和有效株率均呈极显著正相关(p﹤0.01),相关系数分别为0.66、0.71、0.60和0.28。苎麻地上部生物量与株高、茎粗、鲜皮厚度、分株数和有效株率的关联度分别为0.7913、0.7933、0.8034、0.7158和0.7399,表现为鲜皮厚﹥茎粗﹥株高﹥有效株率﹥分株数。通过最优关联度综合评价,筛选出10份与标准品种关联度较大的苎麻种质。Relationships between the major agronomic traits of 94 ramie varieties have been studied using grey correlation degree analysis. The results showed that ramie biomasses were significantly correlated with plant height,stem diameter,fresh bast thickness and harvest ratio. The correlation coefficients were 0. 66,0. 71,0. 60 and 0. 28 respectively. The grey correlation coefficient with ramie biomasses was fresh bast thickness ﹥ stem diameter ﹥ plant height ﹥ harvest ratio ﹥ ramet number,and it was 0. 8034,0. 7933,0. 7913,0. 7399 and 0. 7158 respectively. 10 ramie varieties were superior to the other varieties using the method of optimal correlation degree.
