Abstract: The fertility of Japanese common wheat cultivar Norin 26 and its alloplasmic line with Ae. crassa cytoplasm was studied at different sowing stages in spring season under the condition of normal light period and in greenhouse with no light supplement in winter season in Huhhot. The results indicated that: (1) The rate of sterile plant of alloplasmic line of Norin 26 was 100% in all the different sowing stages. The male sterility was expressed as pistillody of stamens in form. (2) The seed-setting percentages in bagged spike were 40.85% (half male sterile) at first sowing (28/3) , 18.72% (Highly male sterile) at second sowing (7/4) and 0 (completely male sterile) at the third sowing (17/4) , respectively. (3) The fertility of both Norin 26 and its alloplasmic line was normal in greenhouse with no light supplement in winter season.

Key words: D2-type cytoplasm, Alloplasmic line, Wheat, Photoperiod-sensitivity, Cytoplasmic male sterility
