Karyomorhological Variations in Pennisetum americanum (L.) Leeke.
Karyomorphological analyses of three male sterile lines of Pennisetum americanum, their maintainers, two inbreds and two hybrids, which are morphologically distinct showed variations in their karyotypes. The three male sterile lines 732 A, 834 A and 843 A revealed differences in karyomorphology.
