‘Keunpum’ is a mid-late maturing, high yielding, giant embryo rice (Oryza sativa L.) cultivar which is adapted to central plains and was developed to be used as (germinated) brown rice. It is resistant to multiple diseases with a good grain quality. This cultivar was derived by crossing a giant embryo rice variety ‘Keunnun’ and a mid-late maturing, multi-disease resistant rice cultivar ‘Samkwang’-it has good palatability of cooked rice. The growth period of this cultivar is approximately 117 d from seeding to heading, with a culm length of 88 ㎝, panicle length of 20 ㎝, 13 panicles per hill, 136 spikelets per panicle, and 1,000-grain weight of 19.1 g brown rice. This variety has low tolerance to cold stress and premature germination similar to ‘Keunnun’ but exhibits high resistance to lodging. In addition, ‘Keunpum’ is resistant to bacterial blight (race K1, K2, K3), rice stripe virus, and is moderately resistant to leaf and neck blast. Its average milled rice yield for three years reached 5.34 MT/ha, which is 10% higher than that of ‘Keunnun’. In the brown and germinated brown rice of this cultivar, the total dietary fiber content are 6.45% and 6.71%, and the GABA (γ-amino butyric acid) content are 6.61 and 39.47 mg/100 g, respectively. In addition, the total contents of polyphenol, flavonoid, and tannin were higher in ‘Keunpum’ brown rice than in ‘Keunnun’. The DPPH and ABTS radical scavenging activities were 75.23, 116.08 mg TE/100g, respectively. These functional components and antioxidant activities play an important role in inhibiting diseases and the aging process of the human body. Therefore, it is expected to be used as a basic data in the manufacture of secondary processed products using germinated brown rice (Grant No. 7684).

Korean. J. Breed. Sci. 2020;52(4):448-453.   Published online December 1, 2020
DOI: https://doi.org/10.9787/KJBS.2020.52.4.448

A new six-rowed covered barley cultivar ‘Hohyang’ with spring sowing adaptability, lodging tolerance, and high yield was developed from the cross between ‘Saegangbori’ and ‘Durubori’ by the National Institute of Crop Science, RDA, Korea, in 2016. It has a compact spike and long awn, and its growth habit (vernalization requirement) was classified as group II. The averaged heading date was April 21, which was 1 day earlier than that of the control varietal, ‘Olbori’. The culm length was 78 cm, which was similar to that of ‘Olbori’; however, ‘Hohyang’ has a stronger lodging tolerance. Its spike length was 4.7 cm, 655 spikes/m2, 55 grains/spike, and 31.9 g for 1,000 grains. It also showed similar winter hardiness and a superior resistance to barley yellow mosaic virus (BaYMV) compared to that of ‘Olbori’. ‘Hohyang’ was well adapted to spring sowing conditions from March 6 to April 3. Regarding quality, ‘Hohyang’ had the same protein and β-glucan content as ‘Olbori’, but higher polyphenol content than the control cultivar. The yield of ‘Hohyang’ in the regional yield trial was 6.68 ton/ha in upland zones, and 5.06 ton/ha in paddy fields, which were 6% and 15% higher than those of the control cultivar, respectively. If there is rain during the fall planting season, ‘Hohyang’ is suitable for sowing and cultivation in spring (Registration No. 7374).

DOI: https://doi.org/10.9787/KJBS.2020.52.2.151

The rice cultivar ‘Misiru’, which is ideal for rice flour production by dry milling, was developed by the rice breeding team at the National Institute of Crop Science (NICS), Rural Development Administration (RDA), Korea, in 2017 to vitalize the rice processing industry. It is derived from a cross between ‘Daeripbyeo1’ and ‘Seolgaeng’. ‘Misiru’ was grown on a middle plain area by ordinary cultivation methods. The heading date was on August 13, culm length was 85 cm, and there were 12 panicles and 112 spikelets per panicle. The ripened grain ratio was lower than that of ‘Hwaseong’; however, the 1,000 brown rice weight was 30.8 g, about 8 g heavier than that of ‘Hwaseong’. ‘Misiru’ showed medium resistance to blast but susceptibility to bacterial blight, viruses, and insect pests. It was resistant to lodging, whereas pre-harvest sprouting rate and cold tolerance were similar to those of ‘Hwaseong’. The milled rice appeared non-glutinous opaque, with opaque grain rate of 83.7%. The rice grain was soft and starch granules in the endosperm were of spherical type, similar to wheat. The grain contained 6.4% protein and 18.6% amylose (the content of the latter was similar to that in ‘Hwaseong’). However, its milled rice recovery rate was lower than that of ‘Hwaseong’. The average size of dry-milling rice flour was 64.4 μm, and the rate of damaged starch was 5.2%, lower than that of ‘Hwaseong’. ‘Misiru’ milled rice yield was 5.66 MT/ha, 8% higher than the yield potential of ‘Hwaseong’. The cultivar ‘Misiru’ is thus suitable for rice flour production by dry milling (Grant No. 7682).

DOI: https://doi.org/10.9787/KJBS.2019.51.3.277

As a result of the efforts to breed a high yield naked barley cultivar with disease and stress tolerance in response to climate change and proper double cropping of barley and rice in a paddy field. A new naked barley cultivar named ‘Hogang’ was developed from the cross between ‘Suyoung’ and ‘Geukjosuk 55’ at the National Institute of Crop Science, RDA, Korea, in 2016. ‘Hogang’ is a naked barley cultivar used for powdering and mixing with rice. It has good cooking quality, high whiteness, water absorption rate, and expansion rate. Among other quality characteristics, β-glucan content (5.5%) was higher than that of ‘Saessalbori’ cultivar, while the amylose content (21.7%) was lower than that of ‘Saessalbori’. ‘Hogang’ has a short culm length of 69 cm and it is resistant to BaYMV as well as lodging-resistant. As in ‘Saessalbori’, the maturity date of ‘Hogang’ is May 26th. It has large seed size and grain weight of 34.6 g per 1,000 grains. The yield potential of ‘Hogang’ was 4.56 MT/ha, which was 7% higher than that of ‘Saessalbori’. ‘Hogang’ is expected to spread in BaYMV-prone areas since it is a stable and resistant cultivar.

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).

‘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.
