Abstract

Banding patterns were revealed in the somatic chromosome of 4 species Iphigenia Kunth using HCl-Giemsa staining techniques. There was considerable variation both regarding the amount and distribution of bands; C-banding of chromosome promises to be the most valuable technique for routine chromosome analysis due to its inherent simplicity, sensitivity and stability of the material obtained. HCl- Giemsa banding technique was used to study Heterochromatin (HC) banding pattern in genus Iphigenia. The genus Iphigenia is a monocot. The species studied here named as, I. pallida (Baker), I stellata (Blat), I. magnifica (A and R) and I. indica (Linn.) were characterized by 2n= 22 chromosome. The chromosome complement exhibited telomeric and centromeric HC. I. magnifica (A and R) and I. indica (Linn.) showed more banded chromosomes than I. pallida (Baker) and I. stellata (Blat). Telomeric bands were mostly present on short arm of the chromosomes.
