Rice research in Korea during the past 100 years has gone through tremendous changes and improvements as the country underwent a turbulent history of transformation. Full-scale R&D modernization began in the 1970s, when the government focused policy on achieving self-sufficiency in rice in order to establish the foundation for national economic growth. A major landmark was reached by the development of the rice variety “Tongil” and its cultivation technology, which was at the core of the unprecedented Korean “Green Revolution”. Since achieving self-sufficiency in rice, the breeding goal of Korea moved from increasing yield to improving grain quality as more consumers began to seek high quality food products in the 1980s. This change led to the establishment of the high quality rice breeding platform for enhancing the global competitiveness of Korean rice to cope with the opening of domestic rice market in the 2000s. Currently, the major breeding goals in rice are developing premium quality cultivars for table rice and specialized cultivars for boosting processed food industry. To date, the National Institute of Crop Science has released a total of 300 rice cultivars, including 202 table rice and 98 specialized usage cultivars. Diverse technologies have been developed and utilized for breeding new rice cultivars to meet changing needs. In the next 100 years of rice breeding, the convergence of traditional crop improvement technologies and the new breeding technologies utilizing recent advances in biotechnology will play a crucial role in enhancing breeding efficiency.

Anther culturability of CGMS(Cytoplasmic and genetic male-sterile) lines was studied in relation to the pollen-development stage and the effect of sterile cytoplasms in Japonica rice. Callus induction rates of CGMS lines were 45.2%~61.8% in COA-ms and 4.1%~8.1% in WA-ms. Regeneration frequencies ranged from 20.2% to 27.7% without any particula difference between two different cytoplasmic male-sterile lines. Gwanakbyeo and Gwanak COA-ms showed the same callus induction ability along evry pollen-development stages. Callus induction rate of Gwanak WA-ms anther in early uninucleate stage was similiar to that of Gwanakbyeo, however, that was drastically decreased after the stage. It was discussed that sterile pollens caused by sterile cytoplasms were different from S- or E-pollens occuring in normal plants in response to anther culture. Sterile cytoplasms of COA-ms and WA-ms did not affect directly the callus induction and plant regeneration. The regenerated plants derived from anther culture of MS lines were all male-sterile.

Palatability and texture analysis of nine Korean rice cultivars were investigated to select the most appropriate rice variety for the cooked-rice processing. The rice cultivars studied consisted of Samkwang, Seonpum, Wolbaek, Andabyeo, Dasan-1, Ilpum, Haiami, Jungsanggold and Chindle. They revealed the moisture, protein, amylose and starch contents of 10~12, 5~6, 12~19, and approximately 90%, respectively. Among the evaluated rice varieties, WB exhibited the lowest amylose content (12.7%) and Jungsanggold the next (17.2%). In the rapid-visco analyzer test, Jungsanggold, Chindle, Wolbaek and Seonpum revealed a low value of final and setback viscosities than other varieties. Using a toyo meter analyzer, Chindle, Haiami, Samkwang were selected as having high toyo palatability values, while Dasan-1, Wolbaek and Andabyeo revealed low values. Toughness and adhesiveness of all nine cooked rice varieties were highest in Jungsanggold, Chindle and Ilpum. Also, palatability of cooked rice was highest in the following order: Chindle (80.03) > Samkwang (76.21) > Jungsanggold (74.08). The results of this study suggest that Chindle may be effectively used to produce processed cooked rice.

‘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).

Germinated brown rice (GBR) has received considerable attention over the last decade as a means of enhancing the nutritional value and health-promoting functions of rice. The effect of germination on the physicochemical and textural properties of brown rice (BR) was investigated in different rice varieties (Samkwang, Misomi, Chindeul, and Hyeonpum). Cooking properties, such as water absorption, expanded volume, and soluble solids were significantly increased by germination in all rice varieties. Textural properties (hardness, toughness, adhesiveness, and stickiness) of cooked samples were determined using a texture analyzer. Hardness and toughness were decreased by germination, whereas stickiness and adhesiveness increased significantly. These results revealed that germination leads to improvements in the cooking and eating properties of BR. In Rapid Visco Analyzer (RVA), significant reductions were observed for peak viscosity, break down, set back, and final viscosity after germination. Although the amylose content of Misomi was slightly decreased by germination, that of other varieties increased significantly. Germination induced no noticeable change in the average chain length of amylopectin in Misomi, Chindeul and Hyeonpum, but led to a significant increase in Samkwang.
