시설절화용 장미 "그랜드킹"은 경남농업기술원 화훼연구소에서 육성한 신품종이다. 다수성인 적홍색 대륜계의 'Bixa'을 모본으로 병해충에 강한 대륜계인 'Redsandra'를 부본으로 2000년도에 인공교배 하였다. 2000~2001에 걸쳐 가시가 적은 계통을 GR004-1 등 15 계통을 양성 우수한 형질을 가진 GR004-1번 계통을 최종선발 하였다. 2006년 농작물 직무 육성 품종선정위원회에서 "Grandking" 을 명명하였고 화색은 Red-Gr

A New bicolor standard rose (Rose hybrida Hort.) cultivars was developed in the Flower Research Institute, Gyeongnam ARES after going through seeding and line selection in 2000, and their characteristics were examined three times from 2003 to 2006, ‘edme’was crossed between ‘iolina’and ‘kito’and it had a red Petals of a red-group (RHS No. 46A), few thorns and standard large flowers with a good harmony between ray and flower center Petals. The vase life of cut flower was 10 days. Registered as a commercial cultivars in 2006, the new cultivar can be planted in most greenhouse production region of Korea.

Scented lettuce (Lactuca sativa L.) may be highly valued in certain lettuce growing areas, and the trait may be useful as a marker for genetic studies in lettuce. Crosses were made between the scented cultivar ‘Baimach’ and the nonscented cultivar ‘Oaklea

The content of sucrose is one of the most important characters in the value of quality of melon fruit. For genetic studies of sucrose content, a wild melon GM42, as a very low sucrose parent (mean, 9.82 mg · g^-1 fresh wt) was crossed with a hig

Indica 벼의 원형질체들로 부터 효과적인 식물체 재분화 방법을 개발하였다. 이 방법은 배형성 진탕 세포 배양체로 부터 나출된 원형질체들을 feeder cell들이 agarose에 embedded된 배지 표면에 놓인 filter membrane 위에 배양하는 것이다. Feeder cell로서 Lolium multiflorum 세포배양체를 사용했을 때가 Oryza ridleyi를 사용했을 때보다 효과적이었고, 원형질체 평탄효율은 세포 배양체 age에 따라 달랐지만 최고로 0.68％ 까지 증가되었다. Carbohydrate source로서 maltose를 사용하거나 maltose와 sucrose를 1:1로 조합했을 때가 sucrose 단독으로 사용했을 때보다 식물체 재분화율이 증가되었고, 고농도의 agarose를 이용하여 원형질체로부터 유도된 캘러스를 dehydration시켰을 때 또한 재분화율이 괄목하게 증가되었다. 식물체 재분화율은 control 캘러스로부터 3.1∼30.6％ 였지만 dehydration처리한 캘러스로부터는 30.7∼70.7％까지 증가되었다. 원형질체로 부터 유도된 식물체들은 형태적으로 정상이며 개화했다.
