Abstract

Abstract: Observation of anther in spring Raphanussativus L.male sterility line(4-05A)and maintainer line(405 B)was made by means of paraffin section method in order to determine the time that the anther development was inhibited and the sterile mode.The results showed that the meiosis of the connective of the sterile line and it’S main.miner line are normal, Tetrad can yield microspores, the sterile line(4-05A)Degenerated at Uninucleus microspore at periphery, The disintegrated tapetum cells infiltrated into the location around the pollen mother ceils and conglutinated with the pollen mother cells.

Key words: Spring Raphanussativus L., Male sterility, Cytology
