본 연구는 쌀의 다양한 용도개발을 위하여 당질미 계통들의 작물학적 및 이화학적 특성을 조사한 그 결과는 다음과 같다. 1. 당질미 계통들의 간장은 평균 90 cm로 남평벼에 비하여 6 cm정도 컸으며 현미 천립중은 $10.2{\sim}22.2g$으로 남평벼보다 가벼웠다. 또한 현미 평균 수량은 $159{\sim}473kg/10a$로서 큰 변이를 보였다. 2. 당질미들의 아밀로스를 제외한 일반성분 및 무기성분의 함량은 대부분의 경우 남평벼보다 많았으며 당함량은 남평벼에 비하여 최저 2.4에서 최고 6.1배 가량의 높은 당함량을 보였다. 특히 다른 당에 비하여 sucrose 함량이 높았다. 3. 아밀로펙틴사슬분포에서 당질미 계통들은 $DP{\leq}12$의 비율이 높고 $12<DP{\leq}24$의 비율이 낮은 것으로 나타나 phytoglycogen 합성이 많아진 것으로 사료되며 또한 호화특성은 대부분의 당질미 계통들은 매우 낮은 점도 특성을 보였다. This study was carried out to investigate the agronomical and physicochemical properties of five newly bred sugary lines in YARI (Yeongnam Agricultural Research Institute) that developed from the cross of sugary and Hwayeongbyeo, Hwasambyeo and Seomjinbyeo. Culmlength of newly bred sugary lines were longer than that of Nampyeongbyeo as $84.2{\sim}99.3cm$. However the weight of 1,000 grains and yield were lower than that of Nampyeongbyeo by two to three times. According to physicochemical properties, most of the new bred sugary lines showed low contents of amylose and mineral compare to normal varieties. And all sugary lines showed much higher amount of the sucrose and glucose contents compare to Nampyeongbyeo. Especially the sucrose content of newly bred sugary line, 55413, was 5 times higher than that of Nampyeongbyeo nevertheless, fructooligosaccharide and isomaltooligsac charide were not detected. The amylopectin constitution of sugary lines showed more chairs of DP (Degree of Polymerization)<12 but fewer chains of DP $13{\sim}24$ compare to Nampyeongbyeo. Newly bred sugary lines were lower viscosity in RVA (Rapid Viscosity Analysis).

‘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)

A rice variety ‘Dabo‘ is a japonica rice (Oryza sativa L.) with good eating quality, lodging tolerance, and resistance to rice stripe virus (RSV) and blight bacterial disease(BB). It is developed by the rice breeding team of Yeongdeog Substation, National Institute Crop Science, RDA in 2012. This variety derived from a cross between ‘Yeongdeog31’ with good plant type and ‘Milyang165’ with good eating quality conducted in 2001/2002 winter season. A promising line, YR23160-31-2-1-5-B-3, selected by pedigree breeding method was designated as the name of ‘Yeongdeog53’ in 2009. After the local adaptability test was carried out at seven locations from 2010 to 2012, ‘Yeongdeog53’ was released as the name of ‘Dabo’ in 2012. ‘Dabo’ is short culm length as 69 cm and medium-growth duration. This variety is resistant to races, K1, K2, and K3 of bacterial blight and stripe virus and moderately resistant to leaf blast disease. ‘Dabo’ has translucent and clear milled rice kernel without white core and belly rice, and good eating quality as a result of panel test. The yield potential of ‘Dabo’ in milled rice is about 5.90 MT/ha at ordinary fertilizer level of local adaptability test. This cultivar would be adaptable to south plain, east-south costal area, and south mid-mountainous area.
