‘Yeongbo’ is a variety of japonica rice (Oryza sativa L.) with good eating quality, resistance to rice stripe virus, rice dwarf virus, and bacterial blight disease. It was developed by the rice breeding team of the Yeongdeok Branch, National Institute Crop Science, Rural Development Administration in 2014. This variety was derived from a cross between ‘Yeongdeog35’ with good eating quality and ‘Saekyehwa’ with good plant type in the 2002 summer season. A promising line selected through the pedigree breeding method, YR24269-1-2-1-2-3-3, was designated as ‘Yeongdeog57’ in 2011. After a local adaptability test at nine locations from 2012 to 2014, ‘Yeongdeog57’ was released under the name of ‘Yeongbo’ in 2014. ‘Yeongbo’ had a short culm length of 66 cm and medium growth duration. This variety was resistant to K1, K2, and K3 races of bacterial blight, rice stripe virus, and dwarf virus, and moderately resistant to leaf blast disease. ‘Yeongbo’ had translucent and clear milled rice kernel without white core and belly, and good eating quality according to a panel test. The yield potential of ‘Yeongbo’ in milled rice was approximately 5.75 MT/ha at an ordinary fertilizer level in the local adaptability test. This cultivar would be adaptable to middle plain area, south plain area, Yeongnam plain area, east costal area, and south mid-mountainous area. (Registration No.6804)

‘Haedamssal’ is an early maturing and rice stripe virus disease-resistant cultivar adaptable for early-transplanting cultivation that was developed by the rice breeding team of the Department of Southern Crop, NICS, RDA, in 2014. This cultivar was derived from the cross YR25869 (YR21247-B-B-B-49-1/Sasanishiki BL4//Koshihikari) and YR25868 (Unkwang//YR21247-B-B-B-49-1/Sasanishiki BL4) made in the 2005/2006 winter season and was advanced to the F5 generation by a bulk breeding method using rapid generation advance. To incorporate rice stripe virus resistance, marker-assisted selection on the RSV gene was conducted in 3-way and 6-way cross F1 generation using the tightly linked marker RM6897. From testing in the replicated yield trial in 2011, a promising line YR26258-B-B-B-33-3 was selected and it was designated as ‘Milyang276’. A local adaptability test of ‘Milyang276’ was performed at three locations from 2012 to 2014 and it was named as ‘Haedamssal’, which was a good eating quality variety. The culm length was 67 cm in yield trials, which was 4 cm shorter than ‘Jopyeong’. The number of spikelets per panicle was lower than ‘Jopyeong’, whereas the number of tillers per hill was higher. This variety was resistant to RSV disease, bacterial blight, and leaf blast disease. The milled rice yield of ‘Haedamssal’ was 5.48 MT per ha at the early transplanting in the local adaptability test. ‘Haedamssal’ is well adapted to early transplanting cultivation in the southern plain area (Registration No. 6811).

In chronic renal failure, to reduce the burden on the kidneys, it is necessary to provide patients with therapy based on a low-protein diet. To cope with this situation, low and easy to-digest protein rice variety is helpful. ‘Geongyang2’, low glutelins rice cultivar, was developed by the National Institute of Crop Science (NICS), RDA, Miryang, Korea in 2012. ‘Geongyang2’was derived from a cross between ‘Junambyeo’and‘Chugoku 173’ as a source of low glutelin and amylose. The pedigree of ‘Geongyang2’was YR24174-B-B-B-B-46 and designated as the ‘Milyang262’ in 2009. The local adaptability test of ‘Milyang262’ was carried out at six locations from 2010 to 2012. ‘Geongyang2’ is a mid-maturing ecotype with 65cm in culm length and the number of spikelet/panicle and 1,000 grain weight of brown rice were slightly lower compared to those of ‘Nampyeongbyeo’. ‘Geongyang2’ is resistant to bacterial blight and virus disease while susceptible to major insect and pest. The glutelin and amylose contents of ‘Geongyang2’ were 63.1% and 11.5%, respectively. The milled rice yield of ‘Gyeongyang2’ is 4.61MT/ha at the ordinary transplanting of the local adaptability test. This cultivar would be adaptable to the plain paddy field of middle, honam and yeongnam province of Korea under ordinary cropping system.

This study was conducted to investigate the levels of phytotoxicity of Japonica×Indica-type rice varieties to HPPD(4-hydroxy phenylpyruvate dioxygenase)-inhibiting herbicides known for their efficiency to control the sulfonylurea-resistant weeds. The plant injury and rice yield of three Indica × Japonica rice (long grain, cv. Hanareumbyeo, Hanareum2, Dasanbyeo) were evaluated by application rate of HPPD-inhibiting herbicdes, benzobicyclon and mesotrione+pretilachlor (MP), and butachlor as control in transplanting rice in 2012 -2013 in Miryang. The herbicide rates of 350 g, 140 g a.i. ha-1 for recommended rate(1x) and 750 g, 280 g a.i. ha-1 for 2x with benzobicyclon andmesotrione+ pretilachlor (MP), respectively, were applied as pre-emergence treatments while only the 1x concentration of 1,500 g a.i. ha-1 was used for butachlor. All three Indica × Japonica rice cultivars were extremely sensitive to both benzobicyclon and MP herbicides even at the 1x rate as reflected by high visual injury of leaf chlorosis and the injury was more severe at 2x rate than 1x concentration. The percentage of foliar chlorosis of Indica × Japonica rices at the 1x rate was only 34 ~ 64% for benzobicyclon at 14 days after treatment(DAT) and 63 ~ 75% for MP at 7 DAT but the injury was more severe at the 2x rate with 76 ~ 83% for benzobicyclon and 83 ~ 89%. However, the leaf chlorosis injury of the three rice varieties recovered at 1x rate of benzobicyclon and MP about 30 DAT but rice plant death of 6.5 ~ 11.5% for benzobicyclon and 2.1 ~ 3.3% for the MP was observed at the 2x rate, respectively. The heading date of the injured rice plant was delayed by 1 to 2 days and panicle number per square meter, ripened grain ratio and 1000-brown rice weight were decreased due to the injury of rice plant by the herbicide treatments as compared with the control treatment of butachlor. Yield of the Indica × Japonica rice varieties treated with benzobicyclon and MP was significantly reduced by 5 ~ 9% even at 1x rate and 14 ~ 28% at 2x rate, respectively. The result indicates that MP and benzobicyclon should not be used for weed control in Indica × Japonica varieties and rice plant should be transplanted again to some extent at 2x rate of the benzobicyclon and MP herbicides.

Recently, concerns have been voiced about the high eating quality rice in the market. To cope the high quality demands in rice market, a rice cultivar ‘Jinsumi’ which is showing high grain quality and multi-resistant to diseases was developed by the National Institute of Crop Science, RDA, Miryang, Korea. ‘Jinsumi’ was derived from a three-way cross of ‘Milyang165’ and F1 plant of YR16195-B-B-B-21-1/Milyang169. The pedigree of ‘Jinsumi’ was YR21999-B-B-B-17-3-1 and designated as ‘Milyang 218’ in 2005. Heading date of ‘Jinsumi’ was August 15 as mid-late maturing ecotype. ‘Jinsumi’ showed multi resistant to rice stripe virus (RSV), bacterial blight races of K1, K2, K3 and moderately resistant to leaf blast disease. The grain appearance of ‘Jinsumi’ was translucent and showed 96.6% of head rice ratio. The milled rice yield of ‘Jinsumi’ was 5.74 MT/ha at ordinary transplanting of local adaptability test. ‘Jinsumi’ would be adaptable to the plain area of Yeongnam province in Korea.
