조용조(Yong Cho Cho),문진성(Jin Seong Moon),송주연(Ju Yeon Song),정병룡(Byoung Ryong Jeong) 한국원예학회 2007 원예과학기술지 Vol.25 No.4
Shallot is a foreign crop introduced from France in 1995 as a new overwintering field crop with a aim to develop into an export crop. During the introductory cultivation trials, several problems were raised such as premature growth depression in early summer, sensitivity to summer moisture, and weakened vigor of the seed bulbs following successive propagations. This study was conducted to suggest cultural and propagational solutions to these problems. Genetically stable plantlets were obtained by the basal plate culture. Floral organ culture was considered as a good method because it produced plantlets with multiple shoots after 30 days in culture. However, more time was required for bulblet formation than in the disc culture. It took 140 days to obtain seed bulblets in the basal plate culture, 250 days in the floral organ culture, and 320 days in the meristem culture. Total number of days taken for micropropagation in the basal plate culture was 56% and 44% of that in the floral organ culture and meristem culture, respectively. On the contrary, the speed of propagation of the floral organ culture was 4 to 13 times as high as that of the basal plate culture. To summarize, meristem culture was good for obtaining virus-free bulbs, but was limited by a long culture period and a low propagation speed.

A new bi-colour gerbera (Gerbera hybrida Hort.) ‘Candy’ was developed from a cross ‘Ajax’ and ‘Ximena’ followed by seedling and line selections at the Flower Breeding Research Institute, Gyeongnam Agricultural Research and Extension Services (ARES) in 2004. Characteristic tests were conducted three times from 2002 to 2003. Newly bred ‘Candy’ have shown bi-colour (RHS), green center, semi-double type, and mini flower. It also was in good harmony in ray floret color and flower center color with stable flower shape, and vase life was 12.8 days. The average yield of ‘Candy’ was 115.5 flowers per plant a year in greenhouse yield trials carried out from 2002 to 2003. This cultivar registered for commercialization in 2004. ‘Candy’ would be cultured under greenhouse condition in Korea.
