Evaluation of progenies derived from crossings of LLO hybrids with Asiatic lilies.

摘要

Some triploid LLO lilies were crossed with diploid Asiatic hybrids. Two out of five LLO lilies produced progenies. GISH analysis showed that the progenies had L, O and A chromosomes. The numbers of L and A chromosomes were 12 with some exceptions, but the number of O chromosomes varied from 1 to 10 depending on the progenies. Flowers of the progenies showed characteristics derived from both LLO and AA hybrids. Present results demonstrate triple crossing of the L, O and A genomes is possible when LLO hybrids are crossed with AA hybrids.
