“…The presence of B chromosomes in Artemisia is not unusual. Although no species of this genus are included in the lists of plants with B chromosomes published by Battaglia (1.964) and Jones & Rees (1982), our present finding is consistent with the detection of accessory chromosomes in several other Artemisia taxa (Kim, 1994;Masumori et al, 1995;Valles & Siljak-Yakovlev, 1997;Torrell et al, 1999aTorrell et al, , 2001.…”

Seventeen chromosome counts of 14 Artemisia and one Mausolea species are reported from Uzbekistan. Five of them are new reports, two are not consistent with previous counts and the remaining are confirmations of very scarce (one to four) previous data. Two basic chromosome numbers (x=8 and x=9) and two ploidy levels (2x and 4x) were found. Some correlations between ploidy level, morphological characters and distribution are noted.

“…Plant biologists have long been interested in the consequences of polyploidy for the geographical distribution of plants (Stebbins 1950) because both allo-and autopolyploids are typically separated from their diploid ancestors (Lewis 1980;Levin 1983Levin , 2002. Although such geographic separation is common, range size and degree of overlap between polyploids and their progenitors vary widely among species (Nesom 1983;Stebbins and Dawe 1987;Keeler 1990;van Dijk et al 1992;Masumori et al 1995;Husband and Schemske 1998). The magnitude of such geographic differentiation is critical to understanding the maintenance of diploid and polyploid cytotypes within species and the role of polyploidization in the evolution of ecological tolerances.…”
