Freesia (Freesia hybrida Hort.) 'Sweet Lemon' was developed for the cut flowers in National Institute of Horticultural Herbal Science, Rural Development Administration, Korea in 2015. This hybrid was crossed and selected from 'Teresa' and 'Yvonne' in 2007. Morphological characteristics of the selected freesia hybrid were investigated for 5 years from 2009 to 2014, and then it was named 'Sweet Lemon' in 2015. 'Sweet Lemon' has double and lemon petals (RHS color chart Y2B). The average flower diameter was 6.8 cm and the average yield is 6.7. The growth of the plant is vigorous and the average plant height is 99.0cm, which is 34.7cm higher than the standard cultivar 'Yvonne'. The average floret number per stalk of 'Sweet Lemon' was 10.7, and stalk length was 7.7 cm. The average days to first flowering of 'Sweet Lemon', 126 days, was approximately 20 days earlier than the control cultivar. It's average vase life and yield is 8.7 days and 5.6 cormlets per plant, respectively. Totally 58 of volatile compounds were identified using gas chromatography-mass spectrometry (GC-MS), the major components were linalool, alpha-terpineol, alpha-selinene, and limonene.

This study was carried out to investigate effect of $GA_{3}$ foliar application on the growth and flowering of Limonium spp. 'Ocean Blue' to develop an effective $GA_{3}$ treatment method for a year round commercial production. Plants were treated with different concentrations of $GA_{3}$ 0, 100, 200, 400, and 800 mg.$L^{-1}$ in summer, and 0, 100,200, and 400 mg.$L^{-1}$ in winter at seven weeks after transplanting. The effects of $GA_{3}$ treatment time (0, 10, 20, 30, 40, and 50 days after planting) and plant age (raising during 3, 5, 7, and 9 weeks) was investigated. The $GA_{3}$ treatment advanced bolting and flowering with little difference between the two seasons. In a summer culture the effective concentration of $GA_{3}$ ranged from 200 to 400 mg. $L^{-1}$, while in winter it was found to be 400 mg. $L^{-1}$. The $GA_{3}$ treatment at 10 days after planting significantly reduced days to flowering. However, the greatest cut flower yield was observed in plants treated at 20 days after planting. The $GA_{3}$ treatment to different age plants did not show a significant effect, except in the oldest (nine weeks old plants). In conclusion, to induce early flowering in Limonium spp. 'Ocean Blue', the proper concentration and time of application of $GA_{3}$ was 400 mg.$L^{-1}$ $GA_{3}$ treated to nine weeks old plants at 20 days after transplanting.

A spray chrysanthemum cultivar 'Green Candy' was released by National Institute of Horticultural & Herbal Science, Rural Development Administration, in 2009. The cross between 'Yoko Ono', a spray chrysanthemum cultivar with light yellowish-green double type, and 'Green Bird', a spray chrysanthemum cultivar with vigorous and green double type, was made in Suwon in 2006. After the evaluation of the characteristics under shade culture in summer and retarding culture in spring and consecutive selection from 2007 to 2009, 'Green Candy' was selected finality. The natural flowering time of 'Green Candy' is October 28th, and it is possible to flower all year-round by shade and light culture. It has double flower type with green petals. The growth of plant is very vigorous and the color of the petals is stable when the variety is cultivated under high temperature conditions in summer season. The diameter of flower is 4.1 cm. The numbers of flower per stem and petals per flower are 12 and 217, respectively. The days for flowering under the short day treatment are about 58 and its vase life is 18.1 days in autumn season. 'Green Candy' was applied as No. 2010-212 on March 5, 2010 for variety protection and the plant variety protection rights have been registered as No. 3633 on August 2, 2011 at the Korea Seed and Variety Service.

A new orange-colored, cut flower gerbera (Gerbera hybrida Hort.) cultivar 'Sweety' was developed from a cross between 'Grandeur' and 'Songsongee', followed by selections of seedlings and lines at the Flower Breeding Research Institute, Gyeongnam Agricultural Research and Extension Services (ARES) from 1999 to 2004. Three time evaluations were conducted from 2003 for the detailed characteristics of the new cultivar. 'Sweety' has semi-double type mini- or medium-sized flowers in good harmony with orange(RHS, 38-A) ray florets and a green center. It has good, stable flower shape and strong peduncle, and its vase life was 10.4 days. The average flower yield was about 51.0 stems per plant/year in greenhouse trails during 2003 and 2004. This cultivar was registered to the Korea Seed and Variety Service for commercialization in 2006. Year-round production of this cultivar is possible in the greenhouse condition in Korean climate.

A new orange mini gerbera (Gerbera hybrida Hort.) 'Yetty' was developed from a cross 'Haiti' and 'Nova Zembra' followed by seedling and line selections at the Flower Research Institute, Gyeongnam Agricultural Research and Extension Services (ARES) from 2001 to 2006. Three times evaluations were conducted from 2004 for the detailed characteristics of the new cultivar, 'Yetty' has single type mini flower in good harmony with orange (RHS 25-A) ray floret and browen center. It has good stable flower shape and strong peduncle, and its vase life was 14.8 days. The average yield of 'Yerty' was 98.5 flowers per plant a year in greenhouse yield trials carried out from 2004 to 2006. This cultivar registered for commercialization in 2007.

This study was conducted to obtain basic information on cross breeding for developing bolting resistant variety of Angelica gigas NAKAI which has been subjected to severe yield reduction resulted from flower-stalk initiation during the growth. Compatibility of selfing and/or crossing pollination among 5 local cultivars were tested. Results obtained are summarized as follows. In case of three year old plant, all cultivars emerged March 14 and bolted from May 12 to May 13. Ponghwa cultivar was flowered 3 to 5 days earlier than other cultivars. Flower duration continued 41 to 43 days. Interval of flowering date from main stem to first primary branch, from first to second or second to third primary branch was 9 to 13 days. Emergency of stamen proceeded 4~8 days of pistil initiation demonstrating that Angelica gigas NAKAI is protandrous plant. Furthermore initiation of first pistil was 1~4days later than formation of last stamen in the same flower cluster. Percent pollination of Angelica gigas NAKAI was 52% under natural condition, so called open-pollination, but bagging by enveloping flowers was as low as 0.4~2.4%. In the result of compatibility test, all local cultivars tend to show both of self-and cross-compatibility. Inpollination, ‘Muju’$\times$‘Muju’combination showed highest fertility up to 40.8% whereases cross pollination, ‘Pyeongchang’$\times$‘Inje’combination, showed 67.0% fertility.

This experiment was conducted to examine the treatment conditions for single-color dyeing using the variety 'Akito' which was selected based on the flower size, density, blooming shape, elegance, expression of the dying color. The optimal conditions of dyeing rose flower were pH 3.5 under the $20-25^{\circ}C$, in which the vase life showed 15 days as longest after dyeing. The most suitable flower stage for dyeing was identified as second or third stage at which three petals of flower are opened. $10g{\cdot}L^{-1}$ concentration of dyeing solution with $2mL{\cdot}L^{-1}$ treatment of spreader for rose dyeing gave the best color performance.
