‘Miho’ (Milyang300) was developed as a processing rice by means of pedigree selection. ‘Milyang300’ has slightly opaque seeds with low amylose content (11.2%), unlike cultivars such as Baegjinju and Milky-queen, which have seeds with low amylose but are opaque. ‘Milyang300’ was selected and named ‘Miho’ in 2016. ‘Miho’ is a late-maturing ecotype with an average heading date of August 21^st. It shows mild resistance to leaf blast and strong resistance to rice stripe virus, and bacterial blight (K1-K3); however, it is susceptible to brown plant hopper infestation. The yield capacity of ‘Miho’ determined over 3 years of regional yield trials was 565 kg/10 a. In terms of processing properties, ‘Miho’ shows no significant differences in textural properties when stored for 6-48 h at 3℃ and -18℃. Moreover, the physical properties of ‘Miho’ remain unaltered during freeze-thaw processes. Thus, the low-amylose rice ‘Miho’ may be suitable for the production of refrigerated and frozen cooked rice (Registration No. 7656).

‘Shingil’ was developed as a processing rice for specialization as a rice flour by means of mutation breeding from ‘Hanareum’ MNU (N-methyl N-nitrosourea) treatment. The bulk population was displayed from M₁ to M₆, followed by pedigree methods from M₇, where line selection was carried out based on the amylose content, with opacity in the endosperm. The result was that ‘Milyang317’, which has a somewhat high amylose content as well as a high ratio of starch opacity, was selected and named as ‘Shingil’ in 2017. ‘Shingil’ is a mid-maturing ecotype with a heading date of August 10, showing resistance to both leaf/panicle blast and rice stripe virus (RSV), but susceptibility to Bph. ‘Shingil’ showed a low viviparous germination rate of 5.2%. The yield capacity of ‘Shingil’ was 745kg/10a over two years based on a regional yield test. The amylose content of ‘Shingil’ is 23.4% with the grain showing opacity in most parts of the endosperm, which is caused by the round particle shape, unlike the polygonal shape of ordinary grains. Thus, ‘Shingil’ could be used as a rice flour source in various processing field and dry milling industries where milling costs could be saved (Registration No. 8019).
