Ftype wheat male sterile line is a new “three lines” with karyoplasm interaction.For study the pollen characteristics of Ftype sterile line and screening its restorers and maintainers,the I₂ KI staining method is used to observe pollens of F,BNS,T,K and Vtype wheat male sterile lines at blooming stage,and using 98 hybrid combinations that Ftype sterile line was female and 98 quality wheat lines were male to detect the self seedset ratios on F₁ of combinations.Results showed that:(1) pollen sterility rate of Ftype sterile line reached 95.63% including the highest 67.66% stained aborted rate,19.32% spherical aborted rate and only 8.73% typical aborted.(2) The pollen sterility characteristics of Ftype was most similar to Ktype,the second was Vtype in 5 kinds of sterile lines.(3) In 98 hybridized combinations,11 selfseedset ratios (international) were more than 100% and 18 at 0%-10%.(4)‘Zhoumai16’,M510,‘Xinong 815’ and ‘Xinong 585’ were excellent restorer lines to Ftype sterile line.‘Tianmai 989’,‘Cunmai 4’,CY5475,M460,‘12 Luo1’ and 11GB02 were good maintainers for Ftype sterile line by backcross cultivation.Research suggests that Ftype male sterile line has thorough and stable pollen abortion and easily sought its maintainer resources and excellent restorers on fertility.
