Hardy Kiwifruit (A. arguta (Sieb. & Zucc.) Planch. ex Miq.) is one of the valuable species due to their edible fruits, high content of nutritious substances, especially abundant of vitamin C, and distinctive flavor and medicinal usage. Therefore, we have developed a new cultivar of A. arguta with large fruits and high yielding. For this, 168 candidate plants were collected from wild population in 12 locations from 4 provinces (Chungbuk, Gangwon, Gyeongnam, and Jeonbuk) from 1985 to 1987. A clone bank that contained highly productive, superior genotypes of A. arguta was assembled in 1988, and 32 excellent clones were selected in 1996 through clone tests for growth and fruiting. From these clones, we have regularly investigated yield trials for the fruiting characteristics for evaluation of major agronomic traits, which are the average of Fruit Length (FL), Fruit Width (FW), Weight of Fruit (WF) and Individual Yield (IY), during consecutive 6 years (1997~2002). Finally, we have selected the new A.arguta cultivar, “Chil-Bo” with large fruits and high yielding and registered as a new variety denomination and certificated for variety production and merchandising in 2006 (Table 1). This cultivar is characterized by a tetraploid plant and spheroid type in the fruit shape, and is particularly characterized by large fruit size (Fig. 1). The major agronomic traits of this cultivar showed the large selection effect with an average of 28.4 mm (FL), 36.9 mm (FW), 18.2 g (WF), and 24.2 kg (IY), which are -12.1%, 22.6%, 12.4%, and 210.3% compared to the mean of 29 sample trees, respectively (Table 2).

A new black seed coat soybean variety, “Socheong” was developed at the Yeongnam Agricultural Research Institute (YARI) in 2006. The goal to breed the black seed coat soybean is to develop the cultivar with high yield, lodging tolerance, resistant to disease such as soybean mosaic virus (SMV), and bacterial pustule and seed size. Socheong was selected from the cross between Milyang 78, which was late maturing, susceptible to lodging and SMV and with large seed size and green cotyledon, and Peking which was tolerant to lodging and with small seed size. The preliminary, advanced and regional yield trials for evaluation and selection of this variety were carried out from 2002 to 2006.

Futhermore, it has good characteristics for mechanical harvest, such as lodging tolerance, pod shattering and stem diameter. It also has been identified to have resistance to soybean mosaic virus symptom which was the troublesome soybean diseases. The average yield of Socheong was 2.21 ton per hectare in the regional yield trials carried out in four locations of Korea among seven locations from 2004 to 2006, which was 5 percent lower than the check cultivar Cheongjakong.

The amount of bitter sesquiterpene lactones (BSL) and sugar content of “Jangsu” were similar with “Yeolpungcheokchima” at 46 ㎍/g and 4.8 brix, respectively, but taste is better, more crispy, and sweeter than “Yeolpungcheokchima”.
“Shinmichal1”, a waxy red winter wheat (Triticum aestivum L.) cultivar was developed by the National Institute of Crop Science, RDA. It was derived from the cross “Alchan”/“Chal2”during 1997. “Alchan” is a soft red winter wheat with high yield and good noodle quality. “Chal2” is a waxy wheat line crossed by “Kanto107” (Wx-A1b and Wx-B1b) and “BaiHuo” (Wx-D1b). “Shinmichal1” was evaluated as “Suwon306” in Advanced Yield Trial Test in 2002.

The Heading and maturing date of “Shinmichal1” were similar to “Uri”. Culm and spike length of “Shinmichal1“ were 79 cm and 7.8 cm. “Shinmichal1“ had greater test weight (802 g) and lower 1,000-grain weight (31.8 g) than “Uri” (782 g and 35.2 g, respectively). It has resistance to winter hardiness, wet-soil tolerance, lodging tolerance and moderate post-harvest sprouting damage. “Shinmichal1” had higher flour yield (66.2%), ash (0.73%), protein (10.9%) and SDS sedimentation volume (40.7 ml) than “Uri” (64.7%, 0.53%, 9.3%, and 32.5 ml, respectively) and similar flour color to “Uri”. “Shinmichal1” had higher dough extensibility and lower dough strength than “Uri”. It is 5.2% of amylose content and had typical waxy starch pasting properties. Average yield of “Shnmichal1” in the regional adaptation yield trial was 5.24 MT ha-1 in upland and 5.58 MT ha-1 in paddy field, which was 3% and 8% lower than those of “Uri” (5.39 MT ha-1 and 6.09 MT ha-1, respectively). “Shinmichal1” would be suitable for the area above the daily minimum temperature of -10℃ in January in Korean peninsula.

A cross was made in 1995 between Cymbidium “Tropical Yellow”, a brownish yellow colored petal and medium plant sized variety, and “Lucky Rainbow Rapin Hot”, a light purple-pink petal with red lip and medium sized variety. A cross was made in 1995 between Cymbidium “Tropical Yellow”, a brownish yellow colored petal and medium plant sized variety, and “Lucky Rainbow Lapin Hot”, a light purple-pink petal with red lip and medium sized variety. The eighty seven progenies were obtained after planting and acclimatization in green house.

A new graft cactus (Gymnocalycium mihanovichii) cultivar ‘Suyeon’ was developed from a cross between two pink with black breeding lines ‘9603010’ and ‘9603026’, by line selection at the National Horticultural Research Institute, Rural Development Administration in 2005. It was developed with the aim of breeding a cultivar showing vigorous growth and multiple colors. A line ‘9603010’ was derived from a cross between a black line and a pink line. Investigation into characteristics was conducted three times from 2003 to 2005. The color of both body and tubercle was pink with black. The shape of the globe was round and it had 7 to 9 deep ribs. The spine was short and straight, and its color was brown. Growth was retarded compared to a comparative cultivar ‘Ojack’, on the other hand, showed good propagation capability, setting 11 tubercles per globe. Characteristics of the cultivar could be maintained by vegetative propagation. Growers should take care to protect them from strong sun light and virus infection.
