Hedera helix 11계통, Hedera rhombea 3계통, Fatshedera lizei 1계통, 그리고 Fatsia japonica 1계 통을 수집하였다. RAPD primer 10개를 이용하여 수 집된 3속의 재료들의 유전적 다양성을 측정하였다. 3 속을 재료로 사용하여 밴드간 96.9%의 높은 다형성을 보였다. 총 97개의 RAPD 밴드를 이진화하여 UPGMA 방법을 이용하여 계통도를 작성하였다. Hedera helix 계통들은 모두 1개의 그룹에 속하였으며 8계통의 유전 적 거리는 극도로 적었으며 나머지 3계통 역시 유전적 으로 가까웠다. 하지만 형태적으로는 높은 다형성을 보 였다. 따라서 수집된 유전자원을 이용한 돌연변이체 개 발이 가능성이 있는 방법으로 제시되었다. Fatsia japonica는 유전적으로 관계성이 적어 다른 종들과 평 균 0.63의 유전적 거리를 보였다. Hedera helix와 Fatsia japonica 속간 교배를 통하여 개발된 Fatshedera lizei는 Hedera rhombea 계통들과 함께 계통도에서 위치하였다.

The bulb storability of eight red and ten yellow onion (Allium cepa L.) cultivars grown primarily in Korea was evaluated. During storage, sprouting occurred earlier in red cultivars than in yellow cultivars. In addition, the ratio of sprouted to unsprouted bulbs increased more rapidly in red cultivars than in yellow cultivars. However, not all yellow cultivars had strong storabilities. Bulb storability of three yellow cultivars was as poor as that of red cultivars, suggesting only a slight possibility of a pleiotropic effect of color and bulb storability. Meanwhile, F3 lines of a red cultivar selected based on stronger storabilities showed intermediate storabilities between those of the red and yellow cultivars, implying that strong storability could be obtained by successive selection. In contrast, F1 hybrids from crosses between yellow and red breeding lines showed poor storability compared with the yellow cultivars, indicating that poor storability may be dominant over strong storability. The relationships between color and other traits that potentially affect storability, such as fresh and dry weight, water content, and firmness of bulbs, were evaluated. No significant differences in these traits were observed between the two colors, although the water content of yellow cultivars and the dry weight of red cultivars were slightly higher than their counterparts. Correlation analyses between bulb storability and other traits, including weight, water content, and firmness, also showed no significant correlations. In this study, no correlations were identified between bulb color, storability, and other traits. However, based on these results, red cultivars with stronger storabilities could be developed through successive selection of bulbs with stronger storabilities.

A new deep red colored standard rose (Rosa hybrida Hort.) cultivar, `Best Red' was developed at the Jeollanamdo Agricultural Research and Extention Services (JARES). Seedling and line selection were conducted in 2003 and its characteristics were examined three times from 2004 to 2006. 'Best Red' which was obtained by cross between 'Vital' and 'Cardinal'. It shows a red group color (RHS No. 46C), medium fragrance, and standard flower with good harmony between ray floret and flower center. The upper stem is moderate curved. The average yield during 2004-2006 was 111 stems/m2. Its vase life was 10 days. This cultivar was registered as a commercial cultivar in 2007. It is suitable for greenhouses in all regions in Korea and will be released to farmers in 2009.

A new pale pink colored standard rose (Rosa hybrida Hort.) cultivar, 'Fine Pink' was developed at the Jeollanamdo Agricultural Research and Extention Services (JARES).
