Eleven cytoplasmic male sterile (CMS) lines and their respective maintainer lines were evaluated during kharif,2017 for morphological and floral traits to identify CMS lines with better outcrossing potential and yield. Attempt was also made to study the association among the traits in order to select phenotypes with desirable trait combinations.The data revealed that stigma receptivity has decreased day by day after openingof florets in all the genotypes though the percentage vary from one to other. The maximum stigma receptivity percentage was recorded in CMS 23A (71%) followed by JMS 17(55.8%), CMS 46A(48.6%), CMS 11A(48%), JMS 18A(45.4%), however these lines had lower outcrossing potential which might be due to lower angle of glume opening and stigma exertion. The range of duration and angle of glume opening was from 42.7 minute. to 171.3minute. and 17.7^o to 30.3^o, respectively. Pollen and spikelet fertility data revealed that all the CMS lines studied exceptJMS 14A were found to be good without sterility break down.The outcrossing ratewas positively correlated with the glume opening angle. Stigma receptivity had positive significant correlation with soluble sugar content in florets. Among the tested lines, CMS 59A has been found superior for both outcrossing potential and yield, CMS 46A and CMS 64A were found superior for outcrossing potential.
