Abstract

                                Twenty one CMS lines and their respective maintainer lines were evaluated for floral and morphological characters. All the genotypes showed significant variation for the traits studied. The CMS lines viz., IR 58025A, IR 80559A, IR 79156A, DRR 5A, COMS 14A, COMS 15A, TNAU CMS 2A, CRMS 32A and IR 68897A were found promising for the characters viz., pollen sterility (%), glume angle, panicle exsertion (%), stigma exsertion (%), natural out crossing (%), which would favour good out-crossing during seed production of A x B and A x R combinations.

Key words : Rice, CMS lines, floral traits, pollen sterility.
