摘要:This research investigates the hybridization of species Lilium pumilum Delile, L. regale Wils., L.candidum L., L. monadelphum Bieb., L. martagon L., L. henryi Baker. and cultivars of Asiatic,Trumpet and Oriental hybrids. To overcome fertilization barriers in incongruous crosses, cut-stylepollination and pollination by mixed pollen were performed. The hybrid plants were obtained byin vitro cultivation of excised immature embryos. Cut-style pollination was effi cient when Asiatichybrids were pollinated by pollen of L. pumilum. Cut-style pollination and culture of excised embryoallowed receive few hybrids between Oriental hybrids and L. henryi or L. regale. Pollination of afemale by a mixture of incompatible pollen was more effi cient than cut-style pollination. Hybridplants with random paternity were produced using the pollen mixture
