| Abstract: | Huahui 451, derived from the cross of (Minghui 63/Lemont) F_5∥Xianhui 207, is a new rice restorer line developed by Hunan Yahua Seed Industry Research Institute. It shows ideal plant type with erect and concave flag leaves, medium tillering ability, large panicles with glume tips awnless and colorless, strong restoring ability, high combining ability, high grain quality, medium blast susceptibility, strong heat resistance and good cold tolerance. The hybrids derived from Huahui 451 show both high yield and high quality. Among them, Huayou 451, K You 451 and Yahuayou 451 have been registered and released to commercial production by national or provincial crop variety appraisal committees, H28 You 451, Sanxiangyou 451 and Q You 451 have been certified as fine quality rice varieties in Hunan Province, and the grain quality traits of both K You 451 and Yahuayou 451 can meet the third class of national fine quality rice standards, which indicates a promising application prospect of its hybrids in commercial production. |
