Anthers, microspores and pollen were analysed in planta from archesporium formation to anther dehiscence, using various cyto-histological techniques. |

In non-heading Chinese cabbage CMS lines, anther development was inhibited at the archesporium cell stage, in which the flower size is smaller than 0.5 mm, and no anther sac was formed to produce normal sporogenous cells. |
