Phenotypic characterization of new cytoplasmic male sterile lines in rice (Oryza sativa L.)

Author(s): Minakshi Jain, Rupinder Kaur and Surendra Singh Yadav
Abstract: Characterization of 11 bacterial blight resistant new CMS lines was done for characters like plant height, days to 50 per cent flowering, ear bearing tillers per plant, panicle length, number of spikelets per panicle, panicle exsertion, flag leaf length, angle of floret opening, duration of floret opening and stigma length in rice. The F-test showed the presence of highly differences among 11 genotypes for all the traits evaluated. Significant variation was recorded among the different group of genotypes studied viz., CMS lines for all the characters. PMS 27A and PMS 31A were identified desirable in most of traits like early maturity, short height, good panicle length, good panicle exsertion and stigma length. PMS 17A showed good panicle exsertion, good number of spikelets and wider opening of lemma and palea. PMS 24A excelled in panicle length, stigma length, angle of opening of lemma and palea. CMS lines having characteristics like early maturity, short height, good panicle length and panicle exsertion and stigma length has made a significant influence on out crossing rate.
