The world’s collection of lentil plant genetic resources holding the genetic diversity for crop improvement is held primarily as ex situ collections commonly called genebanks or seed banks. This chapter summarizes the both seed and genetic resources for use in breeding and improving lentil. Technical Abstract: The world’s collection of 33,357 lentil plant genetic resources (PGR) is held primarily ex situ in numerous national and one international (ICARDA) genebank. Genetic diversity studies based on small subsets of global collections with up to +400,000 single nucleotide polymorphism (SNP) markers find weak correlations between population structure and geographic origins. This may have resulted because most lentil accessions originated and were disseminated from Mediterranean regions. They generally fall into three groups: Mediterranean, South Asian and Northern Temperate. Small fractions of the world’s lentil PGR collections have been genotyped to date with high density markers such as SNPs. However, several initiatives are in process to increase the proportion of lentil PGR with high quality genetic sequence data sets. This review will summarize available lentil PGR for the international research community. These resources include available lentil PGR sequences and sequenced resources, as well as projects in progress; and successful candidate gene identification studies using genome-wide association mapping for a wide range of economically important traits. |
