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
Lilium
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
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. Successful cryopreservation of
Lilium
spp. is a way to preserve 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 better direct future studies on
Lilium
cryobiotechnology.
