The rice growing area in Yunnan province of China can be divided into six regions based on climate weather conditions, altitude, ecotype of rice varieties, eco-system, and so on as follows: the alpine and high elevation area of Japonica rice, the cold and warm area of Japonica rice, the Indica and Japonica rice area, the single and double cropping area, the paddy and upland rice area, and the single cropping area of Indica rice. In Yunnan, the annual acreage of rice cultivation has been maintained about 1 million hectares, only 3.8 percent of China’s paddy fields. Amounts of unhulled rice production in 2013 was estimated to be around 6.7 million tons. And average unhulled rice yield per ha was 5.79 tons to 6.70 tons during 2011 to 2013. The three major breeding stages commonly have been for rice breeding program: selection of purelines from native varieties by the first 1960s.: dissemination of introduced varieties from foreign countries in the mid 1960s through 1970s; and creation of new developed varieties by hybridization followed by selection after 1980s. In terms of developing Joponica rice variety, its breeding objectives has been set differently depending on altitude: high yielding, grain quality, cold tolerance, and adaptable to low nitrogen fertilizer varieties for growing in areas of 2,100 m to 2,600 m above the sea level; high yielding, grain quality, resistance to disease, and cold tolerance varieties for cultivating in areas of 1,800 m to 2,100 m; and high yielding, grain quality, resistance to disease, and lodging tolerance varieties for planting in areas of 1,450 m to 1,800 m. In addition, researchers are breeding Japonica hybrid varieties for improving yield potentials in Yunnan Agricultural University.

Uonuma region in Niigata Prefecture is the place that produces the highest quality rice Koshihikari in Japan. The following is a summary of weather information and Koshihikari cultivation status in the region. The average annual rainfall of Uonuma is varied from 1,400 in high altitude to 2,500mm in lowland. The average annual temperature is around to 10.0 ~ 12.0oC, which is slightly higher than of Cheorwon and Unbong in South Korea. The water resource is affluent because of heavy snowfall. Higher sunshine hour in August has a good effect on grain ripening in Uonuma. In Korea, however, sunshine hour at Cheolwon and Unbong in early maturing cultivar growing area is prone to long in September after than in August. Breeding program for introducing rice blast resistance to Koshihikari started in 1986 in Niigata Prefecture. Finally, Koshihikari BL(introduced blast resistance) varieties have developed no differences of Koshihikari in agronomic traits, qualities, and taste, etc. and have been cultivated since 2005 in farmers’ field. Paddy soil fertility is managed by incorporating rice straw and manure, and nitrogen fertilizer is applied at rate of 3 ~ 5 kg/10 a. Transplanting date is May 15 to May 20, and transplanting density is 60 ~ 70 hills per 3.3m2. Midsummer drainage is applied when the tiller number reached to 280 until 360 per 3.3m2. Optimal accumulated temperature from heading to harvest is 950 ~ 1000oC. Target yield of brown rice is 510 kg/10 a.

Irrigation with saline water of rivers and groundwater reservoir into paddy field cause decreases rice production depending on water salinity. The purpose of this research was to determine the critical concentration of water salinity for provision of a basic information on the stable rice production in west costal area of Honam region. A greenhouse experiment was conducted at the 13 levels of saline water [0.01(control) 0.03, 0.05, 0.08, 0.10, 0.13, 0.15, 0.20, 0.25, 0.30, 0.50, 0.70, 1.00%] in transplanted rice using c.v. Cheongho and tolerance to different water salinities was evaluated at three growth stages of the rice plant such as [(35 DAT:Tillering), (81 DAT:Heading), and (106 DAT:Ripening)], respectively. Increasing water salinity significantly decreased grain yield and the higher in salinity the severe effect on yield reduction. The growth responses to water salinity varied at different growth stages of rice. At 35 DAT, increased water salinity decreased plant height and number of tillers significantly. Higher water salinity delayed the days to heading by 2 days (0.05%), 4 days (0.08%) and 7 days (0.1%). The critical water salinity at 35 DAT was below 0.08%. At 81 DAT, Cheongho survived at 0.10 and 0.08% salinity, respectively. However, at water salinity levels above 0.10%, the yield components such as number of panicles and number of spikelet decreased drastically. Thus, it was suggested that the critical water salinity at the mid-stage (tillering~heading, 81 DAT) was 0.05%, At 106 DAT, based on yield index that gives above 50% grain yield, the 0.05% salinity showed the lowest 61.1% grain yield of 19.2 g/plant as compared with the highest grain yield of 31.4 g/plant at 0.01% (control).

Change of Physicochemical Properties in Barley Kernels By High Temperature During the Ripening Stage
This experiment was conducted to clarify the effect of the high temperature on physicochemical properties of barley kernels during ripening stage. High temperature treatment was lasted from each 10, 17 and 24 days after heading(DAH) until the harvest time at 21oC, 24oC, 27oC in artificial climate room. The results showed that ripening period from heading to maturity was tend to be shorter at higher temperature treatment condition and at longer duration treatment condition. and 1000-grain weight was decreased as the ripening period shortened. Furthermore, gelatinization properties was changed by high temperature due to the reduction of starch and amylose contents. As the shortening of grain filling period by a high temperature treatment, the protein content was increased. In the 10 DAH at 27oC treatment, the grain filling period was shortened by 9 days. The starch contents was reduced by 5.7 %, and the protein content was increased by 5.6 % in a such condition. Protein contents was showed negative correlations with amylose, starch contents and gelatinization properties, respectively. Starch contents, however, showed positive correlations with amlyose content and gelatinization properties.

The study was conducted to determine proper seeding rate and nitrogen fertilizer level for the effective seed production of Winter Rye (Secale cereale L.) with randomized block design with three replicates by combining both seeding rates (3, 5, and 7 kg/10a) and different nitrogen fertilizer application levels (0, 3, 6, and 9 kg/10a) in northern area of Gyeongbuk province from Oct. 7, 2013 to Jun. 15, 2014. Emergence and overwintering rates were not influenced but lodging degree was influenced by seeding rate and nitrogen fertilizer level. High lodging were observed at the seeding rates and nitrogen fertilizer levels of more than 5 kg/10a and 6 kg/10a, respectively (p < 0.01). Lodging less than 20% were observed at the seeding rate of 3 kg/10a regardless of the increase of nitrogen fertilizer level, furthermore, no lodging was shown though seeding rate was increased up to 7 kg/10a under the condition without nitrogen fertilizer. No. of leaves per plant, plant height and culm length were increased as affected by the increase of nitrogen fertilizer level rather than the increase of seeding rate. Spike length was shortened as affected by the increase of seeding rate while it was lengthened by the increase of nitrogen fertilizer level with no interaction effect between the two factors. No. of stems and spikes per m2 were influenced by the increase of nitrogen fertilizer level rather than by seeding rate with no interaction effect between the two factors. Grain yield was significantly increased as influenced by the increases of seeding rate (A) and nitrogen fertilizer level (B) with interaction effect (A × B), which resulted in the highest grain yield (310 kg/10a) at the seeding rate of 5 kg/10a and the nitrogen fertilizer level of 3 kg/ 10a. In conclusion, the proper seeding rate and fertilizer application level would be 5 kg/10a and 3 kg/ 10a, respectively to effectively produce the winter rye seeds in northern Gyeongbuk province.

This study was conducted to examine the effects of medium composition on organogenesis towards in-vitro cultured diploid and tetraploid Codonopsis lanceolata and obtain in-vitro mass propagation of superior species of C. lanceolata. Regarding MS medium composition for each concentration, diploid C. lanceolata was found to be declined. However, shoot and adventitious root formation were suppressed with higher mineral salt concentration, and active growth of shootand adventitious root was exhibited as 4.9 cm and 3.2 cm respectively in 1/2 MS medium. While in tetraploid C. lanceolata, it showed 2.9 cm and 3.2 cm respectively in 1/4 MS medium. In the case of sucrose concentration, no consistent decrease was observed for growth of shoot and adventitious root of diploid both at high and low concentration. The growth of shoot (at 3% concentration) and adventitious root (at 7% concentration) was 2.3 cm and 2.0 cm respectively. Although there was no difference in shoot formation of tetraploid C. lanceolata in all concentrations with the range of 1.7 ~ 1.8, there was a slight decrease in shoot growth at high concentration. Results revealed that the adventitious root formation was suppressed at high concentration. Concentration of agar exhibited no significant difference in shoot formation of diploid C. lanceolata at all concentrations. The highest result of adventitious growth (4.1 cm) was observed at 0.8% concentration. Slight inhibition of shoot formation and root formation of tetraploid C. lanceolata was observed at higher concentration. Shoot formation of diploid C. lanceolata also exhibited inhibition at higher concentration. Shoot formation of diploid C. lanceolata was increased at lower pH and shoot growth was the highest (2.3 cm) at pH 3.8. Adventitious root formation was higher at lower pH. Although there was no difference in shoot formation of tetraploid C. lanceolata presenting 1.7 ~ 1.8 regardless of high and low pH, growth inhibition was showed at higher pH. Adventitious root formation and growth showed a little higher result at pH 5.8.

This study was conducted to investigate the total polyphenol, total flavonoid and the antioxidant activity in different origin and parts of Moringa olerifera cultivated in Cheorwon. The extraction yield from leaf, root and stem were 25.5, 23.0, 12.3%, respectively. The total polyphenol content was high in the leaf extracts (15.77 mg/g) followed by root extracts (11.23 mg/g) and stem extracts (3.50 mg/g) but the difference of origin was not observed. The total flavonoid content was high in the leaf extracts (14.78 mg/g) followed by stem (1.36 mg/g) and root (1.14 mg/g). The total flavonoid content of Philippines and Thailand leaf were statistically high compared to india leaf. The DPPH radical scavenging activity was high in the leaf extracts at the 1 mg/ml, 0.25 mg/ml but the difference of origin was not observed. The DPPH radical scavenging activity may be attributed to the presence of several compounds such as polyphenol and flavonoid. Hence consumption of diet supplemented with Moringa olerifera leaves could protect the human against diseases induced by oxidative stress.

Chikso is a Korean native cattle breed along with Hanwoo. Hanwoo cattle have been under the national control program of genetic improvement while Chikso cattle have never been. Therefore, the objective of this study was to compare the growth patterns of Hanwoo and Chikso in terms of body weight and frame size parameters. Body weights and 10 body frame size measures from birth to death of all the animals were collected at Gangwon Livestock Technology Research Institute where Hanwoo cattle and Chikso cattle were raised together. Live body measures up to 24 months of age were used for analyses, which were the measures of the animals born from 1985 to 2015. After comparing the average statistics, records of bulls and steers were further analyzed with general linear models to estimate the best linear unbiased effects of breed and castration status at the time of measurements. Castration statuses were classified by the age at castration. Steers with ‘c.young’ class were castrated at younger than 11 months of ages. Steers with ‘c.yrling’ class were castrated from 11 months to younger than 16 months of ages. And the steers castrated later in life were in class ‘c.mature’. Average birth weights of Hanwoo were 26.1 kg (female) and 28.8 kg (male) while those of Chikso were 24.7 kg (female) and 26.6 kg (male). Average body weight of Hanwoo female calves was 91.1 kg, which was 1.5 kg heavier than that of Chikso female calves. Average body weight of Hanwoo male calves was 84.2 kg, which and age adjusted body weight average was 4 kg heavier than that of Chikso female calves. Body frame size of Hanwoo and Chikso calves at birth or at 3 months of age were not differ, but Hanwoo male calves were some taller in wither height or in hip height than Chikso male calves or than female calves. Differences in body weights of male calves became greater to be about 116 kg at 24 months of age in Hanwoo compared to Chikso. Heavier and larger frame sizes of male Hanwoo than male Chikso were also detected from general linear model analyses. Body weight gains of c.yrling calves were greater than c.young calves after weaning to 18 months of age. And after 18 months of age the differences in body weight gains among castration status were negligible.

This study was conducted to report the census survey results of south Korean Chikso (Korean Brindle Cattle) distribution and to diagnose the current coat color expression patterns. Two years Chikso census showed that there were 2,413 Chikso in 2013 and 2,754 in 2014 in south Korea. Number of animals between 0 to 35 months of age was 1,632 heads in 2014 which comprised 59% of total Chikso population size. The percentages of animals between 36 ~ 71 months of age and over 6 years of age were 31% and 10% of total. Out of 2,416 animals with class numbers assessed by their coat colors, 1,249 heads (52%) were in group I (with black stripes, class no. 1 ~ 3) and the others (class no. 4 ~ 7) were in group II (1,167 heads, 48%). Among the 1,551 animals that were photographed twice in 2013 and in 2014, 226 animals were assessed different coat color class numbers, and round 90% of which were within the ages less than 48 months. The number of animals switched in coat color pattern groups over a year was 56, which was 3.6% of total number of animals on survey. And around 88% of the animals switched in group category was of the animals younger than 24 months of age. Therefore, we conclude that the coat color pattern becomes rather stable at around 24 months of age in Chikso populaion in south Korea.

The study examined qualities including chlorophyll, total phenol, total flavonoid content and antioxidative activity in 7-year-old mistletoe that was artificially cultivated with Japanese apricots as the host. The chlorophyll a content of the artificially cultivated Japanese apricot mistletoe leaves was 7.67 mg/g (old leaves) and 3.17 mg/g (new leaves), while the chlorophyll b content was 0.80 ~ 3.53 mg/g and 1.31 ~ 3.56 mg/g. The carotenoid content of the Japanese apricot mistletoe leaves were in the range of 0.29 ~ 2.48 mg/g, and the old leaves (1.85 mg/g) had a carotenoid content 2.1 times higher than the new leaves (0.89 mg/g). The total polyphenol content of the leaves and nodes of the 7-year-old mistletoe was 60.22 mg/100 g TAE for the leaves and 35.50 mg/100 g TAE for the nodes. Among the host trees, polyphenol content was highest (81.44 mg/100 g TAE) in the old mistletoe leaves of the Quercus mongolica, while the total flavonoid content of the Japanese apricot mistletoe was higher in the new leaves (47.89 mg/100 g RUE) than the old leaves (42.19 mg/100 g RUE). The DPPH radical scavenging ability of the Japanese apricot mistletoe scored a low 22.4 ~ 28.5% in the leaves, but was relatively high in the nodes at 52.4 ~ 80.1%. In terms of 1mg/mL concentration, the new leaves (69.1%) and old leaves (82.3%) of the Quercus monglica mistletoe displayed the highest inhibition rate. Chestnut mistletoe displayed an inhibition rate of 21.9 ~ 31.9% for the leaves, and 35.0 ~ 63.8% for the nodes. These results indicate that Japanese apricot mistletoe would be substitute oak tree mistletoe as a source of bio-active property for functional food and medicine.
