Abstract

Lilium is a subbstantial genus administered throughout temperate and cooler regions of the Northern Hemisphere consisting approximately 110 species. The genus possess a great genetic diversity in many valuable horticultural traits which is manifested in flower colour, forms, shape, size, fragrance, resistance to diseases, and many physiological characteristics. Intensive agricultural practices, climate change and industrialization are having a straight impact on biodiversity. Comprehensive understanding of the species, including levels and form of genetic variation forms the basis for the successful management and safeguarding of populations of rare, endangered or threatened species. The biodiversity become important components of different ecosystems. Use of single new improved varieties of crops for large areas is a big threat for crop biodiversity. This review concentrates to provide species-level information on biodiversity in the genus lilium and their future use in breeding programs. We focus mainly on species used in breeding programme and grown mainly for cut flowers and pot production. For example; trumpet shaped Lilium species showed comparative better prospective for exploitation than other species. We also present a brief summary on research area that needs further development using biotechnological techniques like molecular assisted breeding, QTLs and GISH/FISH and chloroplast genomes for comparative and phylogenetic analyses.
