Pachytene Analysis in the Genus Pennisetum (L.) Rich

Abstract

Pachytene chromosome analysis was studied in three species with different basic chromosome numbers (x) in the genus Pennisetum viz. P. ramosum (2n=2x=10), P. glaucum (2n=2x=14) and P. hohenackeri (2n=2x=18). The studies pointed out chromosome differentiating characteristics in between different species as well as within the same species. It was concluded that the length of the chromosomal complement remains almost same irrespective of differences of basic chromosome number. Appearance of longer chromosomes was observed with decrease of chromosome numbers in three species.
