Abstract

Salvia virgata Jacq. (Lamiaceae), popularly known as fatmanaotu, is used as wound healing and spreads naturally in Turkey. The purpose of this study is to determine the diploid chromosome number, detailed chromosome measurements, B chromosomes and karyotype asymmetry of S. virgata. The results showed that the diploid chromosome number is 2n = 32 + 0-2B in S. virgata. The karyotype formula is 2n = 4x = 32 = 24m + 6sm + 2st. The length of the chromosomes ranges varied from 0.56 to 1.65μm. Total haploid and mean haploid length are 18.10 and 1.13 μm, respectively. The centromeric index values varied from 19.54 to 48.57. The intrachromosomal asymmetry value (MCA) and interchromosomal asymmetry value (CVCL) are 20.28 and 28.68, respectively. The karyotype of S. virgata close to symmetric type. In this study, detailed chromosome measurements and 0-2B chromosomes of S. virgata were showed for the first time. The species has small chromosomes shaped in median, submedian and subterminal.
