There is a need to breed and distribute domestic varieties of Lilium Asiatic hybrids because most of the lily bulbs cultivated in Korea are imported from foreign countries. The Lilium Asiatic ‘Butter Pixie’, ‘Mona’ and ‘Tiny Bee’ varieties collected in 2000 had been self-pollinated from 2002 to 2014. In 2016, Lilium Asiatic ‘Bright Yellow LiA’ was developed as an F₁ hybrid whose cultivar was generated by crossing ‘L₂-17-4’ and ‘L₂-32-5’. It was obtained by 6th generation self-fertilization of the combination ‘Mona’ x ‘Butter Pixie’ for the maternal line and 7th generation self-fertilization of ‘Tiny Bee’ for the paternal line. ‘Bright Yellow LiA’ was assessed for homogeneity using a regional adaptability test, and was shown to be preferred by consumers from 2016 to 2018. ‘Bright Yellow LiA’ flowers are yellow and bowl-shaped with a few brown spots. The number of flowers per plant was 4.8, which was relatively more flowers than other cultivars, and the flower diameter was small at 12.7cm. The flower inflorescence was racemose, while the attitude of the longitudinal axis was erect. The plant height was 39.2 cm with 32.9 leaves per plant and 7.5 cm in leaf length. ‘Bright Yellow LiA’ showed a high preference for gardens because it had a longer flowering period, smaller flower diameter, shorter plant height, and thicker stem than those of the control, ‘Tiny Bee’. Moreover, this cultivar has the advantage of being able to reproduce and propagate by seeds since the parents are a pure line.
