ABSTRACT
The
mitotic chromosomal dcfferences of three varieties of maize (Zea mays ever/a,
'Lea mays saccharata and Zea mays turnicata) from root tips were investigated
using squashing method. 0.05g of Colchicine, 3: 1 ethanol-glacial acetic acid
and 70% of ethanol was used for pretreatment and fixation. l N HCl were used
for hydrolysis and 2g of orcein was use for staining. the diploid number of
1/.ea mays everta, Zea mays saccharata and Zea mays turnicata was 2n 20 each,
well spread with few overlapping chromosomes were obtained. Chromosome I with
the highest value was the longest chromosome were as the shortest chromosome
and the shortest chromosome is chromosome X. In Zea mays everta chromosome I H
and V was metacentrics while the rest are non-metacentries. In Zea mays
sacharata, chromosome I and II arc metacentric while the rest arc
non-mctaccntrics. In Zea mays turnicata, chromosome I. II and three arc
mctaccntrics while the rest are nonmetacentries
