Kenaf is a kind of annual bast fiber crop which belongs to Hibiscus Maliace and its main obejectvie is phloem fibe. In this study,we randomly selected 18 varieties from kenaf natural group planted in Hannan Sanya as research objective,which belongs to early variety,medium variety,late variety separately. And then 9 plants were randomly selected from each variety to measure the effective plant height and first flower node. We made the correlation analysis and regression analysis between effective plant height and first flower node from these plants. The results showed signficant linear correlation between effective plant height and first flower node. The first flower node can be uesd as an important marker of fiber yiele breeding of kenaf.
