Alchanmi’, a japonica rice variety, was developed from a cross between ‘Junam’ and ‘Chilbo’ by a rice breeding team at the NationalInstitute of Crop Science and Icheon, Agricultural Technology Center in 2018. The heading date of ‘Alchanmi’ was August 10 in the middleplain area-two days later than that of ‘Hwaseong’. ‘Alchanmi’ had a culm length of 69 cm, 16 cm shorter than that of ‘Hwaseong’, and 103spikelets per panicle. The viviparous germination rate of ‘Alchanmi’ was 24.4%. It showed resistance to blast, bacterial blight (K1, K2, K3race), and stripe virus, but was susceptible to the K3a race of bacterial blight, dwarf and black streak dwarf viruses, and plant hoppers. Themilled rice of this variety exhibited a translucent and medium short grain shape. The cooked rice grains of ‘Alchanmi’ had an excellent palatabilityindex (0.7) and showed lower amylose content (18.6%) than that of ‘Hwaseong’. The grain milling characteristics of ‘Alchanmi’ were betterthan those of ‘Hwaseong’, especially the head rice milling recovery ratio and head rice ratio (96.2%). ‘Alchanmi’ showed 5.83 MT/ha of milledrice productivity at 6 sites under ordinary cultivation (Registration No. 8132).

To evaluate pre-harvest sprouting(PHS) characteristics of four Korean japonica rice cultivar, ‘MS11’, ‘Japonica1’, ‘Japonica2’ and ‘Jinmi’, which were developed in order to be adapted to tropical region, one Tongil-type, ‘Segyejinmi’ and one indica, ‘IR72’, we examined the viviparous germination rate(VGR) in growth chamber and field condition at International Rice Research Institute, the Philippines and National Institute of Crop Science, Korea, respectively. As results, VGR of three japonica rice cultivars were higher than that of ‘Segyejinmi’, Tongil-type and ‘IR72’, indica. And the VGR of ‘MS11’, ‘Japonica1’ were lower than that of ‘Jinmi’, parent of former two rice cultivar, meaning that it has more improved than its parent. In particular, among japonica rice cultivar, VGR of ‘MS11’ was the lowest both in temperate and tropical regions and that of ‘Japonica2’ was the highest both areas. However, VGR of those cultivar raised, VGR of tolerant two was still higher than that of indica cultivar. These results showed that in terms of viviparity, PHS tolerant ‘MS11’ and ‘Japonica1’ were suitable for and ‘Japonica2’ was inappropriate to cultivation in the tropical regions.

‘Keunpum’ is a mid-late maturing, high yielding, giant embryo rice (Oryza sativa L.) cultivar which is adapted to central plainsand was developed to be used as (germinated) brown rice. It is resistant to multiple diseases with a good grain quality. This cultivar wasderived by crossing a giant embryo rice variety ‘Keunnun’ and a mid-late maturing, multi-disease resistant rice cultivar ‘Samkwang’-it hasgood palatability of cooked rice. The growth period of this cultivar is approximately 117 d from seeding to heading, with a culm lengthof 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 varietyhas 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 riceyield for three years reached 5.34 MT/ha, which is 10% higher than that of ‘Keunnun’. In the brown and germinated brown rice of thiscultivar, 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/100g, 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 antioxidantactivities play an important role in inhibiting diseases and the aging process of the human body. Therefore, it is expected to be used asa basic data in the manufacture of secondary processed products using germinated brown rice (Grant No. 7684).

‘Jowoo’, an early maturing, high biomass yielding rice (Oryza sativa L.) cultivar with high feed value and multiple disease-insectresistance, was developed for winter forage crop-whole crop silage (WCS) rice double cropping. It was derived from a cross between a highbiomass and multiple disease resistant line ‘Suweon519’ and an early flowering, high yielding Tong-il type variety ‘Gaya’ that harbored Bph3and BPH26, conferring brown planthopper (Bph) broad resistance. This cultivar had a growth period of approximately 106 days from seedingto heading, 97 cm culm length, 24 cm panicle length, 12 panicles per hill, 120 spikelets per panicle, and 1,000-grain weight of 22.1 g asbrown rice in the central plain region of Suwon. This early flowering rice variety was tolerant to premature germination and cold stresses,especially showed higher grain fertility than ‘Nokyang’ at a cold-water (17℃) irrigated screening nursery. Further, ‘Jowoo’ exhibited high lodgingresistance in the yellowing ripening stage, an optimal period for harvest. In addition, ‘Jowoo’ was resistant to leaf and neck blast, bacterialblight (race K1, K2, K3, K3a), rice stripe virus, and small Bph and was also moderately resistant to Bph. Its average dry matter yield forthree years reached 18.2 MT/ha, the highest among early flowering rice varieties and 19% higher than that of ‘Nokyang’. This cultivar had72.2% total digestible nutrients, which is also higher than that of ‘Nokyang’. In the Korean peninsula, ‘Jowoo’ grows well in the centraland southern plains and can be harvested 30 days after heading. This helps improve its feeding value and digestion rate in livestock (GrantNo. 8133).

최근에 등록된 mesotrione+pretilachlor(MR) 및 bensulfuron-methyl+mesotrione+pretilachlor+pyriftalid(BMPP)에 대한 벼 생태형간 약해 반응을 조사하기 위해 통일형(장립종)및 일본형(단립종) 각 3 품종을 표준량과 2배량을 처리하여 온실에서 포트시험한 결과는 다음과 같다. 제초제 MP 및 BMPP에 대한 약해 반응은 벼 생태형에따라 달랐는데 통일형 품종은 모두 감수성을 보였으나 일본형 벼는 약해가 발생하지 않았다. 통일형 벼는 제초제 처리 후 5일부터 백화증상을 보였고 7일에 약해증상이 뚜렷하였으며 처리 후 14일에는 약해증상이 처리 후 7일 보다 약해지는 경향이었다. 약해정도는 처리농도가 증가할 수록 약해 발생이 심하였다. MP 및 BMPP에 대한 통일형 벼 품종의 초장억제율은 90g a.i. ha-1(표준량)에서 18~43%, 배량에서 30~50% 억제되었고 건물중은 초장보다 억제가 더 커 표준량에서는 46~73%, 배량에서는 65~82%가 억제되었고 억제정도는 농도가 증가할수록 컸다. 하지만 대부분의 일본형 벼는 제초제 2배에서도 약해증상을 보이지 않았으나 초장 및 건물중이 약간 억제 되었다. 벼 생태형별 MP에 대한 50% 생육억제 농도를 조사한 결과, 통일형 벼는 37g a.i. ha-1로 일본형 벼의 476g a.i. ha-1보다 12.9배나 낮았다. 이상의 결과에서 mesotrione을 함유하고 있는 MP 및 BMPP에 대한 벼 생태형간 반응에 차이가 있고, 초다수형 벼 재배시 초기잡초발아전 제초제로서 MP 및 BMPP의 사용을 자제하는 것이 바람직하다. Greenhouse experiment was conducted to evaluate tolerance of six rice cultivars, three Indica×Japonica rice (long grain, cv. Dasanbyeo, Segejinmi and Hanareumbyeo) and three Japonica rice (short grain Nampyung, Ilpumbyeo and Junamjosaeng) cultivars, to mesotrione+pretilachlor (MP) and bensulfuron-methyl+mesotrione+pretilachlor+pyriftalid (BMPP) in transplanting rice. Two herbicides were applied at 90 g and 180 g a.i. ha-1 to three to four leaf stage rice at 5 and 15 days after transplanting, respectively. Related study was also conducted to compare GR50 for Indica×Japonica and Japonica rice cultivars at different MP rates. Response to two herbicides varied with respect to rice cultivars and herbicide rates. All Indica×Japonica rice cultivars exhibited susceptible to both MP and BMPP as reflected by increased visual injury, shorter plant height and higher plant dry matter reduction when compared with non treated rice cutlivars. The degree of foliar chlorosis by MP at 90 g a.i, ha-1 was 5~6 at 7 days after treatment(DAT) but it was decreased to 3~6 at 14DAT. The degree of leaf chlorosis treated with 180 g a.i. ha-1 MP was 6~7 at 7DAT and it was also decreased to 3~8 at 14 DAT. The plant hight of Indica×Japonica rices was inhibited by 18~43% at application of 90 g a.i. ha-1 MP and 30~50% at 180 g a.i, ha-1 MP. The dry matter reduction was greater than that of plant height inhibition, showing 46~73% at 90 g a.i. ha-1 MP and 65~82% at 180 g a.i. ha-1 MP. Similar leaf chlorosis injury and growth inhibition of rice cultivars was observed in the BMPP treatment. The injury and growth inhibition by MP and BMPP increased with increase in herbicide rate from 90 g a.i. ha-1 to 180 g a.i. ha-1. However, most of the Japonica cultivars are tolerant to MP and BMPP at both rates. There was no visible leaf chlorosis but plant height and dry matter production were slightly reduced at 180 g a.i. ha-1. Based on GR50 valus determined in redyction of shoot dry weight for MP, the Indica×Japonica rice showed 12.9 fold lower compared with the Japonica rice. The result indicates that rice cultivars vary in tolerance to hebicides of MP and BMPP and Indica×Japonica rices were more susceptible than the Japonica rices to the MP and BMPP.

‘Yeongwoo’, a mid-late flowering, high dry matter yielding rice (Oryza sativa L.) cultivar with high feed value and multiple disease-insect resistance, was developed for whole crop silage (WCS) use. It was derived from a cross between a high biomass and brown planthopper (Bph) resistant ‘SR25848-C99-1-2-1’ and high yielding Tong-il type, ‘Yongmun’ which had diseases resistance. This cultivar had about 117 days growth period from seeding to heading, 99 cm culm length, 26 cm panicle length, 11 panicles per hill, 125 spikelets per panicle, and 1,000-grain weight of 23.6 g as brown rice in the central plain region, Suwon. This wide and long leafy WCS rice variety was weak to cold stresses, similarly to ‘Nokyang’ but was resistant to lodging in the field, strong to viviparous germination, and good under low temperature germination. In addition, ‘Yeongwoo’ was resistant to leaf and neck blast, bacterial blight (race K1, K2, K3, K3a), rice stripe virus, Bph, and small Bph. Its average dry matter yield for three years reached 20.0 MT/ha, 32% higher than that of ‘Nokyang’. This cultivar had 5.3% crude protein and 71.7% total digestible nutrients, which was slightly lower than that of ‘Nokyang’. In the Korean peninsula, ‘Yeongwoo’ grew well in the central and southern plain and was could be harvested between 15 to 30 days after heading to improve the feeding value and digestion rate of livestock (Grant No. 6800).
