Abstract:

A study was conducted for identification of restorers for their utilization in hybridization programme as the parental lines at Indian Institute of Rice Research (ICAR-IIRR) in Kharif 2016. Forty nine genotypes were earlier screened using gene linked (RM 6100) and candidate gene based (DRRM RF3-10) markers for restorer identification. Further test cross nursery was raised and twenty seven lines test crossed with IR -79156A, those which expressed at least one of the genes to identify the restorers lines. The F1’s (crossed between genotypes and CMS line) expressed different fertility reactions. Out of which 10 genotypes behaved as complete restorers, 10 as partial restorers and 7 as partial maintainers. The present study has a pivotal role in hybrid rice development.
