Abstract
The diploid chromosomes complement of Glycyrrhiza glabra is reported to be 2n = 16 (Darlington and Wylie in Chromosome atlas of flowering plants. George Allen & Unwin Ltd., London, p 163, 1955). Some workers have undertaken caryological analyses to determine morphological and biological polymorphism in different populations of G. glabra, Glycyrrhiza lepidota and Glycyrrhiza echinata. In spite of the morphological variations, these species revealed a stable chromosome number supporting the earlier investigations (Rao 1993). However, total and relative lengths of chromosome pairs and centromeric indices differ among species. Some researches in uzbekhistan have recorded normal meiosis in six different Glycyrrhiza species. (Rao 1993; Ashurmetov 1996).
