Abstract:

Twenty one Kerala rice varieties were crossed with four CMS lines in LxT fashion. The hybrid developed from twenty two crosses between identified restorers and 4 CMS lines were evaluated for heterosis in yield and yield contributing traits. Identified promising hybrids were UPRI95-17A x Aiswarya, UPRI95-17A x Neeraja, UPRI95-17A x Remya and CRMS31A x Kanakom based on high mean grain yield per plant and high standard heterosis over standard check Uma with respect to grain yield and yield contributing traits. Identified superior hybrids can be released for commercial purpose after trail.


Keywords: CMS, L x T, Restorers, Hybrid and Heterosis.
