‘Dodamssal’ was developed as a functional rice by means of a cross between ‘Goamibyeo’, a high amylose cultivar for noodle rice, and ‘Goami2’, a mutant cultivar derived from ‘Ilpum’ treated with N-methyl N-nitrosourea (MNU), with a high amylose content. The bulk population was displayed from F₂ to F₄, followed by pedigree methods from F₅, where line selection was performed based on amylose mutants with an opaque endosperm. Finally, ‘Milyang261’, which has a high amylose content and high resistant starch content, was selected and named as ‘Dodamssal’ in 2013. ‘Dodamssal’ is a mid-maturing ecotype with a heading date of August 10, susceptibility to both viruses and insects, and showed a slightly high viviparous germination rate of 23.4%. The yield capacity of ‘Dodamssal’ was 529 kg/10a over a 3-year regional yield test and would be suitable for cultivation in the middle and southern plain areas of Korea. The amylose content of ‘Dodamssal’ is 42.8%, with a grain appearance of opaque endosperms. Moreover, the starch granule of ‘Dodamssal’ was a round particle shape, unlike the polygonal shape of the ordinary grain. ‘Dodamssal’ is functional variety with resistant starch and dietary fiber contents of 13.6% and 5.3%, respectively (Registration No. 5637).
