Interspecific hybridization between Thai Native lily (Lilium primulinum Bak. var. burmaniacum Stearn) and the introduced lilies (L. longiflorum cultivar Teppoyuri, L. elegans cultivars Apeldoorn, Bellona, Connecticut King, Fastival, Mont Blanc, Sterling Star and L. speciosum cultivars Casablanca and Star Gazer have been made. Fruits and seeds were produced from crosses between L. primulinum var. burmaniacum and L. longiflorum, L. elegans or L. speciosum. The growth of the fruits from these crosses was slow compared with selfed L. primulinum var burmaniacum. Crosses between L. longiflorum, L. elegans or L. speciosum and L. primulinum var burmaniacum were unsuccessful. Twenty five to thirty five days after pollination, embryos were excised and aseptic cultured on Murashige and Skoog (MS) media. After 45 days, embryo started to germinate. Sixty six out of 4196 hybrid seeds were germinated and produced callus and finally plantlet.
