‘Amimyeon’ (Milyang355) is a new Tongil-type rice cultivar developed by NICS, RDA, in 2022, to improve processing suitability and cost competitiveness in the rice noodle industry. Derived from a cross between ‘Milyang288’ and ‘Bukkyeong2012-2,’ it is medium-late maturing ecotype with an average heading date of August 13. It has a culm length of 81 cm, 122 spikelets per panicle, a ripening ratio of 85.2%, and distinct medium-long grains (length-to-width ratio of 2.77). ‘Amimyeon’ exhibits strong resistance to leaf blast and rice stripe virus, with a very low viviparous germination rate (0.2%). Physicochemical analyses revealed high amylose content (26.7%), 8.1% protein content, and a Jasmine85-like aromatic profile. Cooked pasta and noodles made from ‘Amimyeon’ exhibited superior springiness, cohesiveness, and tensile strength compared with commercial products. Its average milled rice yield was 7.24 MT/ha (724 kg/10a), revealing a 4% increase over ‘Dasan’. Thus, ‘Amimyeon’ is highly recommended for plain regions in South Korea as a premium processing material (Registration No. 10644).
Sheonhyangheukmi, black pericarp and aromatic rice (Oryza sativa L.) variety, was developed by the rice breeding team of National Institute of Crop Science (NICS), RDA in 2011. This variety was derived from the cross between Suweon477 and CG2-2-75-4-1-22-3 in 2002 summer season, and selected by a promising line, SR28684-9-2-2-2, was selected and designated as the line of Suweon532 in 2009. The local adaptability test of Suweon532 was carried out from 2009 to 2011 and it was named as Sheonhyangheukmi in 2011. This variety is medium matured with heading date of August 11 in central plain area of Korea. This variety is about 89 cm tall culm length and 122 spikelets per panicle. Its 1,000 grain-weight of brown rice is 17.0 g. This variety is susceptible to leaf blast and and insect pest, but resistant to bacterial leaf blight and moderately resistant to stripe virus disease. This variety has tolerance to unfavorable environment such as cold. Milled rice of Sheonhyanghuekmi is non-glutinous and aromatic endorsperm. This variety has higher anthocyanin content compared to black pigmented variety Heukjinju. The yield potential of Sheonhyangheukmi in brown rice was about 4.75 MT/ha at ordinary fertilizer level in local adaptability test for three years. This variety would be adaptable to the southern plain and middle plain of Korea.
