Abstract
Caryological studies were carried out on ten species of the genus Suaeda
belonging to 27 samples of different populations in Iran. Important
chromosome features including numbers, lengths, centromere locations and
caryotypes were studied. All the species have basic chromosome numbers of
x=9. Chromosome counts of S. acuminata (C.A.Mey.) Moq. (2n=18), S.
aegyptiaca (Hasselq.) Zoh., (2n=l8), S. baluchistanica Akhani and Podl.
(2n=72), S. crassifolia Pall., (2n = 18), and S. microsperma (C.A.Mey.) Fenzel,
(2n=18) are given for the first time. Another chromosome number for S.
fruticosa J.F.Gmelin (2n=72) is also reported
