'Snow Angel' was developed by National Institute of Horticultural & Herbal Science in 2008. A cross was made between phalaenopsis '0361', a white and red lip small-medium variety, and Phalaenopsis 'S98PN1', a white and dark pink lip small-medium variety with pink net pattern. The seedling materials were cultivated to 83 seedling lines from 2000 to 2002. The white and pink lip small-phalaenopsis '99-0404-13' with flowers of round shape was selected by individual selection. The selected line was multiplicated and the growth characteristics were investigated for the first characteristic trial from 2003 to 2007. It was named as 'Wonkyo F2-18' in 2008 and investigated for the second characteristic trial of growth characteristics. The examination was executed for stability, uniformity, yearly reproducibility, and public fancy. It was selected as a high quality cultivar with excellent flower shape and flower color from the selection council of new cultivars for agricultural products, there after it was registered as 'Snow Angel' in 2008.

The effect of medium composition on PLB formation and multiplication and shoot regeneration was studied to establish the micropropagation system of the tropical orchid Phalaenopsis. The highest frequence of PLB formation resulted from the VW medium with 1.2 times ion concentration, 1% sucrose, 1.5g/L PVP or 2.5g/L active charcoal, apple and potato extract and 4g/L gellan gum. The highest ratio of PLB multiplication was obtained from the VW medium with 2% sucrose, apple and potato extract and cotton plate. The shoot regeneration was the most effective with the hyponex medium with 3% apple, 3% potato and 4% banana extract.

A new hybrid, Phalaenopsis 'Pink Marble' was made by the National Institute of Horticultural and Herbal Science, Rural Development Administration, in 2005. This hybrid was selected from self-crossed progenies of P. '21-1' (collected number) in 1999. In 2001, one line was selected based on the aspects such as flower color, leaf shape, flower stalk, and vigorous growth. Trials were conducted from 2003 to 2005 for evaluation and selection of this cultivar. 'Pink Marble' had a medium flowering habit and a dark pink spot (RHS, RPN74B) on white petal and sepal when fully opened. The number of flowers on each peduncle was 7.5, and flower diameter was 52.3 cm. The general impression of petals and sepals is a plate shape. The thick sepal could extend the long flowering time. The average length of leaf and peduncle were 16.5 cm and 6.8 cm, respectively. It had a half-erect leaf form, and was a fast-growing cultivar. This hybrid is relatively easy to clone.

A new cultivar of Phalaenopsis 'Jaha' was developed at Cactus Research Institute, Gyeonggido A.R.E.S in 2006. A crossing between 'KYP74', a pink flower with red lip and 'KYP88', light pink colored flower in 1999 was obtained 264 seedlings. 'Jaha' was finally selected through the test of characteristics from 2002 to 2006. This cultivar has purple color flower with red purple lip, large flower, 11.0 flowers per plant, and 81.0 of inflorescence length. This new cultivar was registered for commercialization in 2006 and would be cultured under greenhouse condition in Korea.

A new Phalaenopsis cultivar 'Little Dew' has been developed by a cross breeding and a line selection at the Flower Breeding Research Institute, Gyeongnam ARES from 2000 to 2007. Characteristics trials for this cultivar was carried out three times from 2004 to 2006. 'Little Dew' developed from a cross between Phal. 'Timothy Christopher' and Phal. amabilis showed white miniature type flowers and a multiflora shape. It has 3~4 flower stalks and many flowers, and long life span of flowers. This new cultivar was registered for commercialization in 2007 and would be cultured well in greenhouse conditions in Korea.

In order to improve the consumer acceptance of fragrant yellow hybrids of $Phalaenopsis$ ($Phal.$), crosses between yellow hybrid varieties were made and the obtained hybrids were investigated for horticultural characteristics as well as difference in fragrance patterns. Cross combination of $Phal.$ Brother lawrence and $Phal.$ Brother saragold yielded good seedling population of 500 plants. Segregation was noticed in color density, spot and stripe patterns on yellow color base of petal and also in fragrance. Six lines with multi-branch on flower stalk and strong fragrance flower were finally selected. Volatile fragrance components were compared among $Phal.$ Brother lawrence, $Phal.$ Brother saragold and their hybrids by GC/SAW electronic nose. In the derivative pattern of chromatogram and polar derivative pattern of fragrance, similar dominant peaks appeared on retention time 7-9 s and some hybrid lines had two strong peaks on retention time 20-25 s, respectively. Also in polar frequency pattern of fragrance obtained by $VaporPrint^{TM}$ image analysis among parent flowers and hybrids, an identical strong peak near 8 s of retention time was shown. This single fragrance component is considered a key element of fragrance in $Phal.$ Brother lawrence, $Phal.$ Brother saragold and their hybrids. This peak could be used as a marker for the breeding of fragrance in $Phalaenopsis$.
