Abstract:

The investigation was carried out to estimate the component of genetic variability and associated parameters among 12 IRRI CMS lines and evaluated for morphological characteristics that influence outcrossing rate in hybrid rice. There was a marked variation in out crossing rate of CMS lines ranging from 18% to 45% under uniform weather conditions for all the CMS lines. Variation in plant height, number of panicle per plant and panicle length appeared to have an influence on outcrossing rate. Phenotypic acceptability, plant height (cm), days to 50% flowering, Panicles per plant and out crossing rate (OCR) here assessed. IR 102760A found best CMS lines with highest OCR % and yield per plant among 12 CMS lines. It means such type of CMS line will be suitable for hybrid seed program and profitable in hybrid rice seed business followed by IR 105688A, IR 102757A, IR 105687A and IR 102571A may also be a promising CMS lines for hybrid rice seed program and heterosis breeding since they possess critical outcrossing traits such as panicles per plant and panicle length. Plant height, panicle per plant and plant length, had moderate heritability with high genetic advance expected in the subsequent generation revealed role of additive gene action. The GCV and PCV somewhat varied from each other for most of the characters studied showed, there is no environmental influence on these traits. Genotypic correlation coefficient were higher than strong relation to phenotypic correlation coefficient indicated high relation among the studied character.
