‘Alchanmi’, a japonica rice variety, was developed from a cross between ‘Junam’ and ‘Chilbo’ by a rice breeding team at the National Institute of Crop Science and Icheon, Agricultural Technology Center in 2018. The heading date of ‘Alchanmi’ was August 10 in the middle plain area—two days later than that of ‘Hwaseong’. ‘Alchanmi’ had a culm length of 69 cm, 16 cm shorter than that of ‘Hwaseong’, and 103 spikelets per panicle. The viviparous germination rate of ‘Alchanmi’ was 24.4%. It showed resistance to blast, bacterial blight (K1, K2, K3 race), and stripe virus, but was susceptible to the K3a race of bacterial blight, dwarf and black streak dwarf viruses, and plant hoppers. The milled rice of this variety exhibited a translucent and medium short grain shape. The cooked rice grains of ‘Alchanmi’ had an excellent palatability index (0.7) and showed lower amylose content (18.6%) than that of ‘Hwaseong’. The grain milling characteristics of ‘Alchanmi’ were better than those of ‘Hwaseong’, especially the head rice milling recovery ratio and head rice ratio (96.2%). ‘Alchanmi’ showed 5.83 MT/ha of milled rice productivity at 6 sites under ordinary cultivation (Registration No. 8132).

‘Danmi’, a sugary rice (Oryza sativa L.), was developed by the Department of Functional Crops, NICS, RDA in 2008. This variety was derived from a cross between ‘Sugary’ a genetic stock of germplasm as a source of sugary endosperm and ‘Seomjinbyeo’ in summer of 1994. The pedigree of ‘Danmi’ is YR16541-14-3-1-2-1-1-3-1-1 which was designated as ‘Milyang 227’ in 2005. Heading date of ‘Danmi’ is August 19, a medium-late maturing ecotype. The total sugar content of ‘Danmi’ was 21.7% with fructose (1.16%), glucose (7.87%), sucrose (9.69%), maltose (0.52%), and raffinose (2.13%), respectively. The appearance of grain is flat shape with 1,000 grain of brown rice is 16.1g. The yield potential of ‘Danmi’ in brown rice is 2.58MT/ha at ordinary fertilizer level of local adaptability test from 2006 to 2008. The sugary rice ‘Danmi’ would be adaptable to the plain paddy field of middle, honam and yeongnam province of Korea.

‘Anmi’ is a new BPH (Brown planthopper) resistant japonica rice cultivar possessing the Bph18 gene derived from wild rice, Oryza australiensis and high yield potential with good grain quality. ‘Anmi’ was derived from a cross ‘Junam’ and ‘IR65482-7-216-1-2’ by a molecular marker assisted backcross breeding. The introgression line ‘IR65482-7-216-1-2’, the source of the Bph18 gene, was used as the donor parent for BPH resistance and ‘Junam’, a BPH-susceptible elite japonica cultivar with good grain quality, was used as the recurrent parent. ‘Anmi’ was developed by three times backcross the F1 plants with ‘Junam’. The heading date of ‘Anmi’ is August 15 in central plain area, which is 5 days later than that of ‘Hwaseong’. It has 77 cm in culm length, 21 cm in panicle length. The number of spikelets per panicle is more than that of ‘Hwaseong’ and 1,000 grain-weight of brown rice is 22.1 g which is less than 22.7 g of ‘Hwaseong’. Milled rice kernel of ‘Anmi’ is clear in appearance, low in amylase content and excellent in palatability of cooked rice. ‘Anmi’ shows resistance to BPH, leaf blast disease, bacterial blight, rice stripe disease but susceptible to other virus disease and insect pest. The milled rice yield performance of ‘Anmi’ is about 5.76 MT/ha in local adaptability test for three years. This cultivar is adaptable to central plain area of Korea.
