Interpretive Summary: Lilium is one of the most popular flower crops worldwide, and some species are also used as vegetables and medicines. The availability of and easy access to diverse plant genetic resources are essential for plant genetic improvements. This manuscript describes technologies for cryopreserving Lilium pollen, seeds, and shoot tips. Lilium is not currently well represented in the USDA-ARS National Plant Germplasm System (NPGS); however, the techniques used for Lilium preservation can be applied to crops maintained in the NPGS.

Technical Abstract: Lilium is one of the most popular flower crops worldwide, and some species are also used as vegetables and medicines. The availability of and easy access to diverse plant genetic resources are essential for plant genetic improvements. Cryopreservation is currently considered as an ideal means for the long-term preservation of plant germplasm. Over the last two decades, great efforts have been exerted in studies of Lilium cryopreservation and progress has been made in the successful cryopreservation of pollen, seeds and shoot tips in Lilium . Genes that exist in diverse genetic resources of Lilium, including those that regulate flower shape, color and size, and that are resistant to cold stress and diseases caused by fungi and viruses, provide a rich source of valuable genetic resources for breeding programs to create novel cultivars required by the global floriculture and ornamental markets. Therefore, successful cryopreservation of Lilium spp. would assist long-term preservation of these valuable genes. The present study provides updated and comprehensive information about the development of techniques that have advanced Lilium cryopreservation. Further ideas are proposed to direct future studies on Lilium cryobiotechnology.
