“…Each genebank has its own history, strengths and weaknesses, which are also reflected in differences in diversity, quality, accessibility, uniqueness and secure storage of the germplasm. Two reviews on lentil ex situ collections have recently been published (Redden et al, 2007;Furman et al, 2009).…”

“…Several national genebanks, including those presented in Table 1, and the genebank at the International Center for Agricultural Research in the Dry Areas (ICARDA) were established after 1970. More than 113 collection missions by ICARDA focused on Western Asia -Near East added 1734 and 374 cultivated lentil and wild species accessions, respectively, to the ICARDA collection (Redden et al, 2007). Gaps remain for germplasm from North Africa and Central Asia (Furman et al, 2009), although some expeditions were conducted recently in the Caucasus and Central Asia (Redden et al, 2007).…”

“…Phenological, morphological and agronomical characters' diversity were subsequently assessed for a core collection of 287 accessions of the USDA ARS lentil collection (Tullu et al, 2001). Redden et al (2007) described that 384 accessions were added to the USDA ARS core collection recently. An ICARDA core collection of 577 accessions was screened for lentil vascular wilt (Sarker et al, 2001).…”

Extensive collections of lentil germplasm now exist in various genebanks around the world. This germplasm including wildLensspecies has been used in plant introduction strategies and in efforts to widen the potential sources of increasing genetic diversity in the breeding programmes of lentil. Improved techniques are emerging to overcome hybridization barriers between species and as a result, interspecific hybrids have been successfully obtained between species. Several interspecific recombinant inbred line populations have been developed. Selected and backcrossed lentil lines are currently in advanced yield trial stages, and desirable traits such as yield, disease resistance and agronomic traits have been incorporated into cultivated lentil especially fromLens ervoides, generating a wider spectrum of variability. Secondly, further expansion of the overall pool of germplasm and examination of allelic variation at the nucleotide level will benefit lentil-breeding programmes by augmenting phenotype-based variation to further advance cultivar development. Genomic resources for lentil are limited now, but this situation is changing rapidly as the cost of genotyping has declined. As a result, two successive expressed sequence tags (EST) projects were undertaken under the NAPGEN EST project initiative (http://www.nrc-cnrc.gc.ca/eng/programs/pbi/plant-products/napgen/.htm) and an Agricultural Development Fund project initiative. We emphasize that creation of intraspecific and interspecific genetic populations, genetic maps, association maps, quantitative trait loci and marker-assisted selection technologies for implementation in the breeding programme will enhance deployment of genes responsible for traits of interest. The economical use of genomic technologies for use in germplasm resource management and genetic improvement is on the near horizon.

“…Recently, wild species of lentil have received much attention as an invaluable genetic resource for widening the genetic base of cultivated lentil varieties. For wild lentil germplasm collection, ICARDA has conducted more than 115 explorations trips and collected 374 wild accessions from diversity rich areas of the world (Redden, Maxted, & Furman, ). Berger, Abbo, and Turner () also demonstrated high level of duplication of CWR collections between genebanks.…”

Widening the genetic base of cultivated gene pool following introgression from wild Lens taxa

et al. 2018

View full text Add to dashboard Cite

Wild Lens taxa are a reservoir of useful rare genes/alleles for widening the genetic base and synthesis of a new gene pool of lentil. To maximize and sustain lentil production, new gene sources are needed to be identified and incorporated into cultivated background. This needs a comprehensive approach to accumulate favourable alleles from distantly related germplasm for widening of the cultivated gene pool and would be the most appropriate strategy to solve the various problems associated with stressed crop production and plateaued yields. Furthermore, expansion of deeper understanding of lentil genomics along with extensive research undertaken in other crop species can provide suitable guidelines to cover the distribution of Lens genus and component gene pools for further remarkable progress in lentil genetic improvement. This review aims at the genus Lens distribution and gene pools, crop germplasm conserved in ex‐situ and in‐situ collection, wild species characterization and evaluation for useful traits of interest to solve production‐related problems, highlight useful gene sources present in different gene pools and the progress achieved for widening the genetic base of cultivated varieties of lentil through wide hybridization and exploring lentil genomics.
