“…In most of the plant species, however, at least a few of the chro mosomes and trisomics could be identified in stan dard somatic karyotypes. For example, in barley (Tsuchiya, 1960) and Petunia axiillaris (Reddi and Padmaja, 1982), three of the chromosome pairs and trisomics could be identified using standard procedures. In beets (Romagosa et al, 1986) eight of nine chromosomes and trisomics could be iden tified in the standard fashion and in A. strigosa, Rajhathy (1975) was able to distinguish all chro mosomes and identify all trisomics from standard somatic karyotypes.…”
