CHROMOSOME MORPHOLOGY IN CYMBOPOGON DISTANS (NEES) WATSON

Published on

Pachytene analysis of bivalents of Cymbopogon distans (2n = 20) was attempted to
establish an idiogram of the species. The chromosomes were marked from 1 to 10
in descending order of their length which varied from 451l to 151l. The short arm
of chromosome 5 is associated with nucleolus. With the combination of characters
like total length, arm ratio and distribution of heterochromatin, all the 10 chromosomes
can be identified.
 

Keywords: Cymbopogon distans, Poaceae, pachytene analysis, idiogram.
