This study was undertaken to study the effect of interspecific pollination of L. longiflorum and L. ${\times}$formolongi as the female parent with Oriental, Martagon and Trumpet group as the male parent by cut-style pollination. In the interspecific pollination of L. longiflorum cv. Gelria and Lorina with Oriental group as the male parent, the corresponding fruits obtained immature embryo were 1, 8, and the mean number of embryo per fruit were 11.0, 3.0, respectively. In the interspecific pollination of L. ${\times}$formolongi cv. Raizan, the corresponding fruits obtained immature embryo were 17, and the mean number of embryo per fruit were 4.0. On the other hand, in the interspecific pollination between L. longiflorum and L. ${\times}$formolongi as the female parent and Martagon and Trumpet group as the male parent, the pollination of L. ${\times}$formolongi as the female parent and L. henryi of Trumpet group as the male parent were obtained only 2 fruits, however no embryo.

This work was undertaken to study the effect of stigmatic and cut-style pollination on self seed set in Lilium longiflorum and L. ${\times}$ formolongi, and their crosses as the female parent with other cultivars/genotypes. Stigmatic pollination of L. longiflorum cv. Gelria and Lorina resulted in cent per cent fruit set with mean number of seeds/fruit of 189 and 70, respectively. However, cut-style pollination resulted in 87％ and 40％ fruit set in Gelria and Lorina, respectively. The corresponding mean number of seeds/fruit was 53 and 20. In L. ${\times}$ formolongi, stigmatic pollination set 80％ fruits with 736 seeds/fruit. On the other hand, cut-style pollination resulted in 47％ fruit set with 81 seeds/fruit. The intraspecific stigmatic pollination of L. longiflorum cv. Gelria and Lorina with other cultivars formed 60％ fruits with a mean number of 18 seeds/fruit. However, only 20％ fruit set with mean number of seeds/fruit of 7 was recorded when cut-style pollination of L. longiflorum cultivar were pollinated with other cultivars/genotypes. In the intraspecific pollination of L. ${\times}$ formolongi cv. Raizan with Novia, fruit set resulting from stigmatic and cut-style pollination was 75％ and 50％, respectively with the corresponding mean number of seeds/fruit of 579 and 98. It was concluded that self as well as intraspecific seed set in the two species of Lilium gets considerably reduced as a result of cut-style pollination.

We studies seed set in the interspecific F1 /backcross hybrids of Lilium species. In the interspecfic hybrid of L. longiflorum cv. Gelria with L.${\times}$ fomolongi cv. Raizan,93％ fruit set was obtained by stigmatic pollination in comparison to 53％ from cut-style pollination. Accordingly, the number of seed set resulting from stigmatic and cut-style pollination was 147 and 53, respectively. Pollination o( both stigmatic and cut-style pollination resulted in 47％ fruit set in the hybrid of L. longiflorum cv. Lorina with L.${\times}$ fomolongi cv. Raizan. However, stigmatic pollination formed 413 seeds, whereas only 24 seeds were obtained by cut-style pollination in this cross. The hybrid of L.${\times}$ fomolongi cv. Raizan with L. longiflorum cv. Come set 40％ fruit with a total of 43 seeds by stigmatic pollination. However, no fruit set was observed in cut-style pollination in this hybrid. Backcrossing the F1 hybrid by cut-style pollination of L. longiflorum cv. Lorina ${\times}$ Asiatic hybrid cv. Chicago with the latter parent led to 53％ fruit set, and 109 embryos were obtained. Likewise, backcrossing following cut-style pollination of L. longiflorum cv. Lorina ${\times}$ Asiatic hybrid cv. Corsia with the latter parent formed 67％ fruits and 107 embryos. However, in the remaining interspecific hybrids, cut-style pollination set no fruit.

'Glory Pink' an interspecific lily cultivar was released in 2007 at National Horticultural Research Institute (NHRI), Rural Development Administration (RDA), Suwon, Korea. The cross and ovule culture was made between FA interspecific hybrid 'FA97-30' (L. formolongi 'Raizan' ${\times}$ Asiatic lily 'A61'), a red colored cultivar, and Asiatic lily 'Sanzio', light red colored cultivar in 2001. Multiplication and bulbing, and characteristic tests were conducted from 2005 to 2006. Flowering time is around the first of July and the plant height is 131.7 cm. Flowers are upward-facing and red-pink (RHS 63C), with size of 11.3 cm. Petal length and width is 9.1 cm and 4.1 cm, respectively. Leaves are 13.8 cm long, 1.4 cm wide. The throat is dark green, and the stigma is light yellow and pollen is light brown. The weight and size of bulb is 51.1 g and 13.2 cm, respectively. For long-term storage, bulbs can be stored under -1 to -2 for year-round forcing.

An interspecific hybrid lily cultivar 'Green Star' was bred in 2005 at the National Institute of Horticultural and Herbal Science (NIHHS), Rural Development Administration (RDA), Korea. The crossing and in vitro embryo rescue was conducted between Lilium FA97-2 (L. ${\times}$ formolongi 'Silky White' ${\times}$ L. Asiatic 'Sunray') and L. Asiatic 'Bomi (Byeongga ${\times}$ Connecticut King)' by cut style pollination method (CSM) at Suwon in 2000. The first selection was done and was tentatively named as 'FA03-5' in 2003. After in vitro multiplication and bulbing production of 'FA03-5' line, growth and flowering characteristic tests were conducted from 2003 to 2005. The evaluation of characteristics and consumer preferences were surveyed at a lily flower show of NIHHS in 2005. 'Green Star' flowered in the middle of June and grew more than 120 cm stem in length. Flowers bloomed facing upward, unspotted in petals and greenish yellow (RHS, Y6D). 'Green Star' was male sterile. Year-round flowering can be done by storing the bulb under $-1.5^{\circ}C$ conditions. It was needed to control the Botrytis disease in wet season.

A FA (Lilium formolongi $\times$ Lilium asiatic hybrid) intersectional hybrid lily cultivar 'Orange Crown' was developed in 2007 at National Institute of Horticultural and Herbal Science (NIHHS), Rural Development Administration (RDA) of Korea. The cross and immature embryo rescue was conducted between female parents 'Migreen' (Lilium formolongi 'Raizan' $\times$ Lilium asiatic hybrid 'A61') and male parent 'A01-187' (L. asiatic 'A96-28' $\times$ 'Sanzio') by cut style pollination method at Suwon in 2001. It was preliminarily selected as 'FA04-27' in 2004. Multiplication, bulb production and characteristic tests were conducted from 2004 to 2007. The evaluation of characteristics and preference were surveyed at a lily flower show of NIHHS at Taean in 2007. 'Orange Crown' flowers in the late of June and grows more than 183 cm stem length. Flowers bloom upward-facing, a little spotted and orange (RHS, O24A) petals. The pollen of 'Orange Crown' was sterile.

This study was carried out to investigate the effect of three different growth retardants for applying pot or bedding plant with 'Rialto', 'Elodie', and 'Raizan'. Ancymidol, uniconazole, and paclobutrazol were applied as a drench at various concentrations. In Oriental hybrid lily 'Rialto', no changes were observed not only plant height but also leaves and flowers in paclobutrazol treatment. But the growth of plant treated with ancymidol was inhibited above 30% compare to control regardless of concentrations. However, numbers of leaf and flower per plant were similar to those of controls. Plant height was similar to nontreated control in $1mg{\cdot}L^{-1}$ uniconazole treatment but that reduced about 30% in drench application of 5 and $10mg{\cdot}L^{-1}$ uniconazole. Asiatic hybrid lily 'Elodie' was not different in growth between application of paclobutrazol and nontreatment as 'Rialto'. While, in all ancymidol treatments, plant height was 50~60% shorter than that of control. Also, numbers of leaves were reduced and days to flowering were slightly delayed in $30mg{\cdot}L^{-1}$ ancymidol treatment as compared with the control. All traits except plant height of $1mg{\cdot}L^{-1}$ uniconazole were similar to control but there were differences of statistical significance between 5, $10mg{\cdot}L^{-1}$ uniconazole drench and nontreated control. Lilium ${\times}$ formolongi 'Raizan' like above two cultivars had no dwarf effect on height in paclobutrazol treatment. In drench application of ancymidol, plant height reduced over 60% than that of control regardless of concentrations. Especially, days to flowering were a little delayed with $30mg{\cdot}L^{-1}$ paclobutrazol treatment. Plant height of $10mg{\cdot}L^{-1}$ uniconazole was about 26% shorter than that of control, but other traits were no differences between uniconazole treatment and control. In result, the drench application of ancymidol and uniconazole was pretty effective for usage as pot lily without great changes of quantitative traits.
