Quinacrine Fluorescent Karyotypic Pattern in Pennisetum americanum (L.) Leeke

Abstract

The Q-banded karyotype of pearl millet was successfully demonstrated. The banding patterns at different stages were analysed and polymorphism in banding pattern of homologues of chromosomes 1, 3, 4 and 6 was observed. They differed in having bands of unequal size or different band positions. The chromosomes showed Q-bands only in telomeric and centromeric regions and intercalary bands were absent.
