Lilium is an ornamental plant with great worldwide commercial importance. Obtaining intra- and interspecific hybrids is a known approach to introduce new traits into the commercial groups and cultivars. However, considering the incompatibility of many intra- and interspecific crosses, resulting from pre-fertilization and post-fertilization barriers, various methods have been employed to obtain new hybrids. L. longiflorum is a Lilium group with great marketability, which exhibits incompatibility in many crosses. Here, we have tried to obtain interspecific L . × fomolongi × L. brownii and L. longiflorum × L. brownii hybrids using the combination of ovary slice and ovule culture. In the study, we obtained some interspecific hybrids in Eorayon 2ho × B (7), and Augusta × B (7), as well as Augusta × KHR, Afjw × KDD, and Augusta × KDD crosses. To the best of our knowledge, this is the first reported successful study obtaining L. xfomolongi × L. brownii hybrids. Evaluating the morphological characteristics of the hybrids obtained, as well as studying the traits introduced from parents, can be topics for future studies
