Nanhui 511, derived from the hybridization between two heavy-panicle type restorer lines Shuhui 881 and Shuhui 527, is a new restorer line in rice. It is characteristic of broad restoring spectrum, strong restoring ability, high combining ability, acceptable grain quality and good integrated agronomic characters. Nanhui 511 was technically identified at a provincial level in August, 2004, and its hybrids Yangxinyou 1 （D702A/Nanhui 511） and D You 6511 （D62A/Nanhui 511） were examined and certified for release to commercial production by the Sichuan Provincial Crop Variety Appraisal Committee in April, 2005.
