[Observation of the pollen mother cell meiosis of male sterile line in rice by using confocal microscopy].

In the present paper, meiosis of male sterile pollen mother cells and fertility of ripened pollen was observed in male sterile line (Xindao97200A) by using laser scanning confocal microscopy (LSCM), beside, the seed setting rate of selfing and artificial pollination was investigated. Abnormal chromosome behaviors during the meiosis of PMC were found with 15.8%, which included lagging chromosome, dragging chromosomes, three poles of spindles, chromosome bridge, micronuclei and asynchrony of the dyad.
