Studies on Meiotic Behaviors of Pollen Mother Cells in Eggplant (Solanum melongena L.)

The cytological study of eggplant is basical for chromosome engineering breeding. Meiotic behaviors of pollen mother cells (PMCs) in eggplant (Solanum melongena L.) were characterized in this paper. The results showed that a simultaneous cytokinesis was observed in eggplant, chromosomes became condensed from prophase I to metaphase I, and de-helixated at telophase I. At diakinesis, most of the chromosome configurations were ring bivalents, while tetrahedral type and decussate type were two typical forms of tetrads. Nonsynchronization in nuclear division were observed which maybe . Besides, the meiosis process of pollen mother cells were correlated with the appearance of buds, and The length of anther from 8mm to 12mm was the best period for Meiotic behaviors of PMC observation. The results obtained from this study could be the basic knowledge for further interspecific hybridization and chromosome engineering breeding of eggplant.
