%X Karyotypes of 10 cultivars of 6 cultivated forms in two cultispecies of Nicotiana(N. tabacum and N. rustica) were studied. All of the experimental materials are amphidiploid. The karyotypes formulae of N. rustica cv. 'Chrysanthemum tobacco' is Zn4x=48=44m(2 SAT) 4 sin. The karyotypes of 9 cultivars of N. tabacum can be simplified as follows: cv. 'Baihuatiegan' 2n=4x=48=34m 10 sin (2 SAT ) 4 st; cv.'Liuyejian' 2n=4x=48=34m 10 sin 4 st;cv. 'NC 89' 2n=4x=48=30 m(2 SAT) 12 sin 6st;cv. 'Maryland 609' 2n=4x=48=36 m 10 sin Zst;cv. 'Havana 211' Zn= 4x= 48 = 32 m 12 sin (4 SAT) 4 st;cv. 'Cigarro wrapper-Indonesia' 2n=4x=48 38 m 8 sin 2 st;cv. 'Burley 21' 2n=4x=48=32m 12sin 4 st icy. 'Sumsum' 2n 4x=48=34m 12sin (2SAT) 2st; cv. 'Aromatic tobacco-Thailland' 2n=4x=48 34 m 12 sin 2st.
