 ABSTRACT

The experiment was conducted with three CMS lines i.e., IR 68887 A, IR 79159 A and APMS 6 A which were crossed with eleven WBPH tolerant diverse male parents in line x tester fashion in order to estimate restorers/maintainer nature. Total 33 hybrids were subjected to pollen study, and observed that, out of 33 hybrids, 6 hybrids have more than 80 per cent pollen fertility, whereas 27 hybrids showed the pollen fertility ranging from 51.1 to 80 percent and they were considered as partial restorers.The identified restorers and maintainers could be utilized for development of new WBPH tolerant rice hybrids and CMS lines in future.

Key words:  Rice, Restorer, Pollen fertility.
