Evaluation of stable performance of cytoplasmic male sterile lines in rice

The experiment was conducted to evaluate the stability of cytoplasmic genic male sterility of different male sterile lines for floral traits and same yield contributing characters. Total eight CMS lines including seven Indian and one IRRI, Philippines were raised during wet season 2007. All the eight CMS lines showed 100 percent pollen sterility. The highest angle of floret opening was recorded by KJT 2A. The maximum stigma exsertion was observed in the CMS line KJT 4 A while KJT 1 A, KJT 6A and KJT 7 A had predictability to perform in favorable environment. KJT 5 A had highest panicle exsertion. It was observed that KJT 4 A CMS line performed better in most of the desirable characters which offer scope of utilizing this male sterile lines for development of three line hybrid in rice.
