A new garden chrysanthemum (Dendranthema grandiflorum Ramat.) cultivar ‘Burning Ball’ was developed at the Flower Research Institute of Chungcheongnam-do Agricultural Research and Extension Services in 2011. ‘Burning Ball’ was bred in 2005 through a cross between the ‘05-72-04’ line with a red-purple flower color as the female parent, and the ‘04-26-22’ line with a red-purple flower color as the male parent. Adaptation trials were conducted for two years, from 2006 to 2007, under natural conditions. To identify morphological and genetic originality, we compared the external shape type with ‘Pretty Ball’ and conducted ploidy and RAPD (Random Amplified Polymorphic DNA) marker analyses. The results indicate that the ‘Burning Ball’ cultivar has unique characteristics compared to ‘Pretty Ball’. As a result, ‘Burning Ball’ will be favorably accepted as a novel bed chrysanthemum in the landscaping industry, contributing to farm income (Registration No. 4184)

The radish (Raphanus sativus L.) is one of the major vegetables of Korea and is consumed as the main ingredient of kimchi. To improve the texture of radish kimchi, herbs, and soup, we attempted to develop a cultivar with a hard texture. Using species native to Jeju Island, we bred ‘Wonkyo10045ho’ which produces short, elliptically shaped roots with a hard texture. Generation progress was made via the self-fertilization method using bud pollination. We selected individuals with good horticultural characteristics from each of five generations grown from 2006 to 2010. Finally, in 2015, the line was named ‘Wonkyo10045ho’, and the granting of plant variety rights (Grant number 6527) was certified in 2017 following an application for the protection of new plant varieties (application number 2015-398). The root characteristics of ‘Wonkyo10045ho,’ include an oval shape, mixed white and green root skin, and a white inner root color. ‘Wonkyo10045ho’ had a sugar content of 4.9 Brix, with excellent sweetness, good taste, and strong pithiness. The average number of seeds per plant obtained via pollination by bees in a small net house was 609.1, suggesting that the strength of its self-incompatibility was not strong and male sterility might be advantageous. Therefore, it is expected that this variety will be useful as a material for improving the competitiveness of domestic farmers and for stable radish exports.

Kimchi cabbage (known as Chinese cabbage) is major vegetable in Korea. An inbred line of ‘Wonkyo20038ho’, was developed by the National Institute of Horticultural & Herbal Science, RDA in Republic of Korea. The microspore culture was carried out using ‘Chunhuigohangwang’ which was introduced from China in 2002. Among 3 DH inbred lines, ‘Wonkyo20038ho’ inbred line was finally selected after field exhibition in 2009. The horticultural traits of ‘Wonkyo20038ho’ inbred line; half-open head, white inner leaf colour, and dark green outer leaf colour. The average (for four years) head weight was 2025.3g, and head width and height were 15.8cm and 32.4cm, respectively. Head shape was narrow elliptic and degree of overlapping leaf was medium. Numbers of outer and internal leaves were 14.1 and 49.8, respectively. Harvest maturity was mid-late maturing type and average of seed yield for five years was 926 seeds. In addition, ‘Wonkyo20038ho’ inbred line is suitable for salad in that it possessed few trichome and narrow elliptic head shape.

Kimchi cabbage (known as Chinese cabbage) is one of the major vegetable in Korea. An inbred line ‘Wonkyo20042ho’, was developed by the National Institute of Horticultural & Herbal Science, RDA in South Korea. The first cross carried out using ‘Norang gwandong’ which had been introduced to Korea in 2007. During segrerating generations, bud pollination carried out using selected plants to fix genetic materials. ‘Wonkyo20042ho’ inbred line was finally selected by breeders from commercial companies at the field exhibition at 2011. The horticultural traits of ‘Wonkyo20042ho’ inbred line were as follows; half-open head, yellow inner leaf colour, and dark green outer leaf colour. The average head weight was 1899.2g, head width and height were 17.5cm and 27.9cm, respectively. Numbers of outer and internal leaves were 14.3 and 66.5, respectively. Harvest maturity was mid-late maturing type and average of seed yield for three years was 723 seeds. In addition, ‘Wonkyo20042ho’ inbred line showed resistance to clubroot disease (race 4 single spore isolation) and possessed thin leaves and small sized head.
