Abstract:Microscopic observations on anther development process of male sterile materials‘Ms2008076’in cabbage(Brassica oleracea var. capitata L.)showed that‘Ms2008076’anther development was hindered at the stage of pollen mother cell differentiation. The main characteristic is that the tapetal cells developed abnormally and pollen mother cell de-gradated rapidly to disintegrate with the ultimate result that the anthers were abortive absolutely.
