영문 초록

‘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).
