Abstract:

The 88 -428BY is found by Wei Baoguo ,w hich is a photoperiod -sensitive male -sterile soybean .Under the articial illuminat ion , the pollens appear to be sterile in lig ht t reatment of 12 .0h/d for 20d ;to be fertilein the t reatment of 15 .0h/d .Comparative studies of the development of pollens of the sterile and fert ile plant sshow there are three breakdow n stages :

⑴At the meiotic division of the pollen mother cell , the 99 %of them show the abnormal synapsis , 9 %of thepollen mo ther cells show abo rted .

⑵Middle microspore stage ,which is the key sterile stage , 89 .3 %of the pollens show abnormal.

⑶The late bicellular pollen stage , 10 % of the pollens show aborted.
