Among the lily hybrids,the Lilium(Oriental × Trumpet)OT hybrids has the abundant variations in flower color and pigmentation patterning,which has become the main direction of lily breeding in the world. The flower color and breeding information of OT varieties cultivated and registered in the world(1958—2018)were sorted out and classified,the history of hybrid breeding of OT hybrids was analyzed,and the contribution value of important parents involved in the origin of OT hybrids was calculated. The breeding process of OT hybrids with various color systems and flower color types was systematically researched. The results showed that there were eight color systems and five kinds of pigmentation patterning in OT hybrids. The different color systems mainly originated from L. henryi,L. speciosum,L. rubellum and L. auratum with the total contribution value of 10.3035,6.7955,4.1250 and 2.5255. The mosaic phenomenon of flower color patterning,the interaction of pigment synthesis pathway and the evolution pattern of chromosome variation in the process of hybridization breeding are the reasons for the formation of abundant flower color.
