ABSTRACT
<p><b>OBJECTIVE</b>Study on the karyotypes analysis of Ferula fukanensis.</p><p><b>METHOD</b>The young roots were treated with 0.000 2 mol x L(1) 8-Hydroxyquinoline for 3 h, carnoy's for 3 h, 1 mol x L(-1) HCl in 5 min,carbol fuchsin coloration for 2 min and the treated roots were utilizied to make the plate for observation.</p><p><b>RESULT</b>The fukanensis is diploid. The chromosome number of somatic cells was 2n = 22. The karyotype formula is 2n = 2x = 20 = 16m + 4sm. The 4th and 10th are submetacentric, and the others are metacentric.</p><p><b>CONCLUSION</b>The karyotype of F. fukanensis belongs to "2A" type of stebbins', and it is a primitive species.</p>
