‘Dahongmi’ was developed to enhance the quality of colored rice by crossing ‘Jeogjinju’, Korea’s red-brown colored rice variety, with ‘Junam’, a variety known for excellent cultivation characteristics. ‘Dahongmi’ is a mid-maturing cultivar harvested approximately 15 days later than ‘Jeogjinju’, suitable for the mid-central plains. Each ‘Dahongmi’ plant bears 14 panicles, similar to that in ‘Jeogjinju’ but with an additional 22 grains per panicle and a heavier 1000-grain weight compared to that of ‘Jeogjinju’. ‘Dahongmi’ exhibited superior low-temperature germination rate (85.1%) and a higher percentage of fertile grains at a cold-water irrigated nursery (36.2%) compared to ‘Jeogjinju’. The stem height of ‘Dahongmi’ is 89.7 cm, similar to that of ‘Jeogjinju’. However, ‘Dahongmi’ has a third node height 9 cm shorter than that of ‘Jeogjinju’, enhancing its resistance to lodging. Furthermore, it displayed resistance to leaf blast, bacterial leaf blight (K1, K2, and K3 strains), and rice stripe virus, ensuring stability during cultivation. The protein and amylose content of ‘Dahongmi’ are 5.5% and 18.9%, respectively, similar to that of ‘Jeogjinju’ (5.9%, 18.3%). The levels of antioxidant components such as total polyphenols and flavonoids are comparable to that of ‘Jeogjinju’. However, ‘Dahongmi’ does not exhibit resistance against bacterial leaf blight strain K3a and delphacidae, underscoring the importance of timely and balanced fertilization for effective early-stage management. ‘Dahongmi’ exhibits better yield, straw strength, and plant architecture compared to ‘Jeogjinju’. It has immense potential for augmenting the yield of high-antioxidant-pigmented rice varieties. In addition, it could provide valuable foundational data for the brown rice processing industry (Registration Number: 8680).

‘Jungdream’ is an early maturing, high-quality rice cultivar developed in 2017 by the crop breeding team at Crop Research Division, GARES, Hwaseong, Korea. ‘Jungdream’ was first developed in 2008 from crossing a medium-late maturity cultivar ‘Chilbo’ and an early maturity cultivar ‘Ungwang’. The heading date of this cultivar is July 28^th in the Gyeonggido Province. Its culm length is 63 cm, and it has 19 panicles per hill and 82 spikelets per panicle. It is a medium-small grain brown rice cultivar with a 1000-grain weight of 20.6 g. Its cold tolerance is lower than that of ‘Hwaseong’, which is the standard cultivar in the central region, as is its degree of lodging tolerance. ‘Jungdream’ is resistant to rice blast and stripe virus diseases but is susceptible to bacterial leaf blight and other viral diseases and pests. The appearance of milled ‘Jungdream’ rice is clear, and its amylose content is 16.5%, which is lower than that of ‘Hwaseong’. The palatability of cooked ‘Jungdream’ rice is better than that of ‘Chucheong’, which is the main cultivated crop in Gyeonggido. Its milling ratio is 75.0%, which is lower than that of ‘Hwaseong’. The yield of milled ‘Jungdream’ rice was 5.42 MT/ha in the local adaptability tests during standard cultivation in four regions from 2015 to 2017. ‘Jungdream’ is highly adaptable to the environmental conditions in the Gyeonggido Province (Registration No. 8236).

‘Gawagi1’ is an early maturing, low amylose rice variety with a medium to short culm, developed by Gyeonggi-Do Agricultural Research & Extension Services, Hwaseong, Korea in 2016. ‘Gawagi1’ was derived from the cross between ‘Baegjinju’ and ‘Sangmibyeo’ in 2004. Heading date was 4th of August 15 day earlier than ‘Baegjinju’ in Gyeonggido. The culm length was 67 cm. It had 15 panicles per hill and 104 spikelets per panicle. It is a medium-grain variety whose 1,000 grains weight of brown rice is 19.3 g. The protein content of milled rice was 6.3%, which is higher than that of ‘Baegjinju’ and its amylose content was 8.2% which is lower than that of ‘Baegjinju’. Its milling ratio is 75.5%, which is higher than that of ‘Baegjinju’. The yield of milled rice was 4.99 MT/ha under the standard cultivation practices at the local adaptability tests in 3 regions from 2014 to 2016. ‘Gawagi1’ is highly adaptable to Gyeonggido, especially to the northern region of Han River.

‘Chamdream’ is a medium-late maturing, high-quality rice cultivar developed in 2014 by the crop breeding team of Crop Research Division, GARES, Hwaseong, Korea, in cooperation with the rice breeding team of the National Institute of Crop Science, RDA, Korea. ‘Chamdream’ was first developed in 2004 from a backcross between the F₁ hybrid ‘Samgwang/Jojeongdo’ and ‘Samgwang’ cultivar. The heading date of this cultivar is August 17^th in Gyeonggido Province. Its culm length is 79 cm and it has 15 panicles per hill and 115 spikelets per panicle. It is a medium-grain brown rice cultivar with a weight of 22.9 g per 1,000 grains. Its cold tolerance is lower than that of ‘Hwaseongbyeo’ and its degree of lodging tolerance is similar to that of ‘Hwaseongbyeo’. This cultivar is resistant to bacterial leaf blight and stripe virus diseases and moderately resistant to rice blast diseases, but it is susceptible to other virus diseases and pests. The appearance of milled ‘Chamdream’ rice is clear and its protein content is 5.4%, which is lower than that of ‘Hwaseongbyeo’. The palatability of cooked ‘Chamdream’ rice is better than that of ‘Chucheongbyeo’ which is mainly cultivated in Gyeonggido. Its milling ratio is 76.8% which is higher than that of ‘Hwaseongbyeo’. The yield of milled ‘Chamdream’ rice was 5.9 MT/ha in the local adaptability tests in standard cultivation in four regions from 2012 to 2014. ‘Chamdream’ is highly adaptable to the environmental conditions of Gyeonggido Province, especially to the southern region of Han River.
