Abstract: Two types of wheat male sterile lines,1B/1R type and non-1B/1R type,and their male maintainable lines were selected to study the agronomical characters,disease resistance,photosynthesis rate and activities of SOD in anthers.The results showed that T.spelta 1BS chromosome made the male sterile lines of Non-1B/1R type produce less haploid and higher plant height than that of 1B/1R type,and there were no significant difference on the disease resistance and agronomical characters between two types of wheat male sterile lines;The male sterile lines of Non-1B/1R type were with higher photosynthesis rate than that of 1B/1R type.There were little difference of SOD activities between two types,which were all with tendency of decrease.There was difference of SOD activities between two types of male maintainable lines.The key period of microspore abortion of two types of male sterile lines was similarly from dinucleate stage to thinucleate stage.

Key words: Wheat, 1B/1R, Non 1B/1R, Male sterile line, SOD
