Characterization and Gene Mapping of a Novel Mutant in Rice Floral Organs

doi:10.3724/SP.J.1259.2011.00506

Abstract

Abstract: We obtained a rice floral mutant, inner flower organ number 6 (fon6), from the progenies of tissue culture of a japonica variety Taichung65. The mutant has double ovaries, multi-stigmas, and 7 to 8 stamens. The mutant trait is controlled by a single recessive gene. The F₂ population derived from the cross between Zhongxian 3037 and fon6 was used for gene mapping. FON6 was mapped to the ~480-kb region between the sequence-tagged site markers PL4 and PL5 on chromosome 6. These results will be useful for cloning and functional analysis of the gene.

Key words: double-ovary, flower organ, gene mapping, multi-stigmas, rice
