The ‘Hangaru’ is a rice variety derived from a cross between ‘Seolgaeng’, which is suitable for making rice wine, and ‘Daeripbyeo1’, which has a heavy grain weight (34.8g) and is suitable for deep fried rice, by the rice breeding team at the National Institute of Crop Science, Rural Development Administration, in 2017. The heading date of ‘Hangaru’ was August 18 and was 10 days later than check variety, ‘Hwaseong’, in Suwon. It had a culm length of 79 cm and 102 spikelets per panicle, and showed similar tolerance to ‘Hwaseong’ when exposed to cold stress. ‘Hangaru’ showed medium resistance to blast disease, but susceptibility to bacterial blight, viruses and brown planthoppers. The milled rice of this variety exhibited an opaque and non-glutinous endosperm. The 1,000 grain weight of brown rice was 32.9 g, which was 10.8 g heavier than that of ‘Hwaseong’; the protein content was 7.0% and the amylose content (19.2%) was similar to that of ‘Hwaseong’. The milled rice recovery rate was lower than that of ‘Hwaseong’. However, opaque grain percentage of milled rice was 88.1%. The hardness of the rice grain was soft and the starch granule shape in the endosperm was round, similar to wheat. The average size of rice flour was 71.0 µm and the damaged starch rate was 6.4%. These results showed that this variety could be suitable for dry milling rice flour production. ‘Hangaru’ had a yield of 5.42 MT/ha of milled rice productivity in ordinary cultivation, which was 99% of that of ‘Hwaseong’. ‘Hangaru’ was adaptable to the middle plain area and Mid-west coast of Korea (Registration No. 7270).
