The use of maize (Zea mays L.) pollen for basic scientific research has been well documented, but the progression of clear cytological features of maize microsporogenesis has not been fully documented. This study was undertaken to identify cytologically the different developmental stages of maize pollen and to correlate them with morphological features of the developing maize tassel. Morphological changes in the length of the tassel, floret, and anther were recorded and correlated with six cytologically defined stages of microsporogenesis: premeiosis, meiosis, uninucleate stage, first pollen mitosis, second pollen mitosis, and mature pollen.Key words: cytogenetics, gametophyte, maize, microsporogenesis, pollen.
