Abstract

Detailed karyological and meiotic studies have been carried out in the diploid species of Gloriosa L. with somatic number 2n=22 chromosomes. This taxon G. lutea Hort. is morphologically distinct with linear and crisped monocolored chrome yellow perianth having pale orange seeds. It is distinct in its cytology and the karyotypic peculiarity with the formula 2n=22=2A'nm+2NM+4N'nm+12T'nm+2SM which supports its tendency of isolation as diploid species. Meiosis is highly irregular with first and second division stages showing large number of laggards. Univalents and multivalents are of common occurrence with high frequency of quadrivalents reflects on genomic instability.
