520 |a Rice flour is useful as a substitute for wheat flour, however, to obtain fine flour, millers need special milling facilities, which increase the cost of milling. To reduce the milling cost, we developed a floury mutant line by irradiating gamma-rays to dry seeds of the japonica cultivar 'Hoshinoyume'. The line was registered as a new cultivar, 'Hoshinoko'. Genetical analysis of the floury trait was conducted using an F2 population derived from a cross between 'Hoshinoko' and 'Corbetti' (a japonica rice cultivar with normal endosperm), which indicated the involvement of a single recessive gene located near the RM163 marker on the long arm of rice chromosome 5, flanking flo4 identified by Kang et al. (2005). Sequence analysis of flo4 showed a two-bp (CA) insertion in the eighth exon of in 'Hoshinoko' compared to that of 'Hoshinoyume', which led to a frameshift mutation. The CAPS-based genotype of flo4 gene completely correlated to the phenotype of endosperm in two populations. This CAPS marker could be helpful for rice breeders to develop new cultivars harboring floury endosperm of the flo4-303 gene
