| Abstract: | Mianhui 2040, derived from the cross of Wanhui 228, an indica-japonica hybridized restorer line, and Doxi 1, a blast resistant indica restorer line, is a new indica type restorer line in rice with strong restoring ability, high combining ability, good blast resistance, good grain quality and heavy pollen load for high yield of hybrid seed production. It is similar to Minghui 63 in response to temperature and photoperiod and it heads 5 days earlier than Minghui 63. The hybrids B You 840 (803A/Mianhui 2040) and C You 2040 (CA/Mianhui 2040) were examined and approved for release in Sichuan Province in 2000 and 2002, respectively. |
