摘　　要：对６个裂叶红麻品种（系）不同光合器官的数量性状与干皮产量作了相关分析。结果表明总叶数、７裂叶数及麻皮长和麻皮宽的光合器官之间及与干皮产量之间的相关都是显著的，而圆叶数、３裂叶数及５裂叶数与干皮产量相关不显著。总对数、７裂叶数及麻皮长的数量性状其广义和狭义遗传力都很低．表明主要光合器官的表现易受环境影响，注意选择圆叶数性状可能有助于培育高产品种。Correlation between quantitative characters of different photosythetic organs and dry bark yield were analysed in six varieties of lines of kenaf with lobed leaves. The results showed that the correlation between total leaves.seven lobed leaves,fresh bark length,fresh bark breadth and dry bark yidld,and between these photosynthetic organs,all were significant,but between complete leaves,three lobed leaves,five lobed leaves and dry bark yield were not significant. The heritabilities in broad and narrow for quantitative characters were most low in total leaves,seven lobed leaves and fresh bark length.It indicates that those of main photosynthetic organs were affected easily by environmental factors. Note of selection complete leaves Character could advantage to breed high yield Varieties.
