ABSTRACT
Cytologists have devised cytological techniques from time to time to obtain precise information on chromosome numbers and chromosome structures and to examine the mechanism of cell division in plant species. These properties are studied by cytological techniques. The basic principles for handling the mitotic and meiotic chromosomes of all plant species are similar and consist of collection of specimens, fixation, and staining. However, cytological procedures are modified depending upon crop species, objective of the experiments, and, above all, personal preference of the cytologists (Darlington and La Cour, 1969; Sharma and Sharma, 1965).
