Abstract
The Lens genus includes the cultivated L. culinaris, and wild subspecies orientalis - the progenitor, tomentosus, and odemensis, are in the primary genepool, while L. ervoides, L. nigricans and L. lamottei are in the secondary – tertiary gene pool. The Middle East is the primary centre of diversity for the primary genepool, with distribution of L. orientalis extending to central Asia, and of L. ervoides extending along the Mediterranean to Spain. The largest Lens collection is held at ICARDA. In situ reserves of Lens diversity are in Turkey and Syria. Documentation and storage of Lens germplasm is discussed.An evaluation database covering a number of genebanks has been developed for lentil germplasm. Core collections are discussed in the context of the generation Challenge program. Application of DNA characterisation is outlined, along with the potential forallele mining for variation in key traits, the study of relationships within Lens and the use of mapping populations. Reference is made to the International treaty for Plant Genetic Resources for Food and Agriculture
