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.

Chrysanthemum (Dendranthema grandiflourm Kitamura) is a member of the Asteraceae and one of the important horticultural crops. The
objective
of this study was to construct a DNA profile database for identification of chrysanthemum varieties using simple sequence repeat (SSR) markers. In order to select SSR markers for the variety identification, we screened 587 SSR primers using 20 varieties. Among them, 27 SSR markers showed polymorphism. We finally selected 14 SSR markers showing peak clearance, high polymorphism and reproducibility in 20 varieties. In conclusion, DNA profile database for 147 chrysanthemum varieties were constructed by 14 SSR markers. A total of 79 SSR alleles were detected and three to ten alleles were detected with an average of 5.6 alleles per locus. The polymorphism information content value ranged 0.287 ~ 0.785 with an average of 0.598. Genetic relationship revealed that genetic distance of 147 varieties ranged from 0.44 to 1.00. The 143 varieties among 147 varieties were distinguished by 14 SSR markers but the 2 varieties developed by mutation breeding and natural variation were not distinguished from original varieties. These constructed SSR profile database will be useful for the selection of similar varieties for candidate variety and for solving problem relating to seed dispute and infringement of plant breeder’s right.
