Verification of the different kinds of meiotic abnormalities in a unique endogamous maize plant was undertaken by analyzing 53324 cells, including meiocytes and meiotic products, scored among 433 male flowers. A total of 6456 cells (12.11%) were affected by certain kind of meiotic abnormality that could impair, in different ways, pollen viability. Abnormalities were related to chromosome segregation, absence of cytokinesis, cytomixis, cell fusion, irregular cell shape, chromosome bridges, and genomic separation. Abnormalities compromised meiotic products and a high frequency of abnormal microspores was produced. High frequency of different kinds of meiotic abnormalities in a unique plant may be explained by gene segregation for meiosis control during selfing. The influence of meiotic abnormalities in the combining ability of inbred lines is discussed.
