Karyotype variability in regenerated plants of Urginea indica Kunth.

Sumita Jha, Sumitra Sen

Abstract

Plants regenerated from callus cultures of diploid Urginea indica Kunth., Indian squill, showed variability in both chromosome number and morphology. In addition to diploids, regenerants included tetraploid, aneuploid and mosaic plants. Structurally altered chromosomes were detected in diploids as well as tetraploids. Structural alterations involved mainly the nucleolar chromosomes.
