[Genetic analysis and gene mapping of an early flowering and multi-ovary mutant in rice (Oryza sativa L.).].

Abstract excerpt

A rice floral mutant was obtained from a japonica variety Zhonghua 11, which was characterized with the phenotype of more stamens, more pistils and early flowering. Genetic analysis showed that the mutant phenotype was controlled by a single recessive gene, which was designed as floral organ number 5 (fon5). To map fon5, an F2 population was derived from the cross between Huajingxian 74 and fon5 mutant. Gene fon5...
