“…In this study, HSW was not affected by the herbicide treatments. However, contrary to the results of the present study, significant reduction in seed size was observed by Sharma et al (2018) in lentil where herbicide-treated plots of all accessions showed significant decrease in the size and volume of seeds.…”

“…The postemergence application of imazethapyr and metribuzin caused significant reduction in GYPLT and PNPLT. Similar results were observed in lentil (Friesen et al, 1986;Sharma et al, 2016Sharma et al, , 2018 and chickpea (Taran et al, 2010) cultivars treated with metribuzin and imazethapyr at postemergence stage. Narrow leaves that were observed after imazethapyr spray reduced the leaf area index (Maalouf et al, 2016a) and therefore affected photosynthetic activity, which led to a poor canopy coverage that ultimately reduced GYPLT.…”

Weeds cause serious constraint to faba bean (Vicia faba L.) productivity. Broad weed control is hampered by the availability of postemergence herbicides to control them, as the current faba bean cultivars are highly susceptible to them. Therefore, the deployment of postemergence herbicide tolerance is desirable in faba bean. To address this, 130 accessions were screened for their response in mature plants under field conditions to the recommended dosage of two herbicides, metribuzin at 250 g a.i. ha −1 and imazethapyr at 75 g a.i. ha −1 at Marchouch and Terbol stations. The recorded herbicide damage score (HDS) varied from 1 (no visual damage) to 5 (full damage with death of more than 50% of plants) at both locations. Low but highly significant (p < .01) and positive correlation (+0.26) was obtained between the recorded HDS at both locations. Both herbicides significantly delayed flowering and maturity time occurrence, reduced plant height and grain yield, and increased number of branches. Reduction index (RI) correlated positively with HDS score at Terbol station in different seasons and at Marchouch in 2016-2017 seasons. Eleven tolerant accessions were identified and further evaluated to 1×, 1.5×, and 2× of recommended dose of both herbicides. The results indicated that the harmful effect of herbicides on grain yield reduction intensified from 13.4 to 27.2% and from −7.6 to 1.8% as the dose of metribuzin and imazethapyr increased respectively from 250 to 500 g a.i. ha −1 and from 75 to 150 g a.i. ha −1 . Tolerance to metribuzin and imazethapyr in eight faba bean accessions was confirmed with no significant reduction in grain yield.

“…This was possible because of the formation of core, mini‐core, and Focused Identification of Germplasm Strategy (FIGS) sets of lentil germplasm, which have been a very useful for systematic evaluation. Significant variation has been reported for yield traits (Erskine, 1983; Erskine, Adham, & Holly, 1989; Kumar et al, 2014), response in flowering to temperature and photoperiod (Erskine et al, 1994; Erskine, Ellis, Summerfield, Roberts, & Hussain, 1990), winter‐hardiness, iron deficiency chlorosis and boron imbalances (Srivastava, Bhandari, Yadav, Joshi, & Erskine, 2000), drought and heat tolerance (Hamdi & Erskine, 1996), herbicide tolerance (Sharma et al, 2018), Orobanche tolerance (Fernández‐Aparicio, Sillero, & Rubiales, 2009), and resistance to fungal diseases and viruses (Erskine, Saxena, & Saxena, 1993; Kumari et al, 2017). Kumar et al (2014) recorded useful genetic variability for days to 50% flowering, secondary branches, number of pods, biological yield, grain yield, and 100‐seed weight in the indigenous lentils.…”

Legumes represent the second most important family of crop plants after grasses, accounting for approximately 27% of the world's crop production. Past domestication processes resulted in a high degree of relatedness between modern varieties of crops, leading to a narrower genetic base of cultivated germplasm prone to pests and diseases. Crop wild relatives (CWRs) harbor genetic diversity tested by natural selection in a range of environments. To fully understand and exploit local adaptation in CWR, studies in geographical centers of origin combining ecology, physiology, and genetics are needed. With the advent of modern genomics and computation, combined with systematic phenotyping, it is feasible to revisit wild accessions and landraces and prioritize their use for breeding, providing sources of disease resistances; tolerances of drought, heat, frost, and salinity abiotic stresses; nutrient densities across major and minor elements; and food quality traits. Establishment of hybrid populations with CWRs gives breeders a considerable benefit of a prebreeding tool for identifying and harnessing wild alleles and provides extremely valuable long-term resources. There is a need of further collecting and both ex situ and in situ conservation of CWR diversity of these taxa in the face of habitat loss and degradation and climate change. In this review, we focus on three legume crops domesticated in the Fertile Crescent, pea, chickpea, and lentil, and summarize the current state and potential of their respective CWR taxa for crop improvement.

“…Around 76% of ICARDA lentil accessions have been characterized for morphological and phenological attributes (http://www.genesys-pgr.org; Kumar, Rajendran, Kumar, Hamwieh, & Baum, 2016; Kumari et al., 2018; Sharma et al., 2018; Sita et al., 2017). Under the Canadian‐led project AGILE, a lentil diversity panel (LDP) consisting of 324 accessions was phenotyped for phenological attributes in nine different locations around the world for two seasons (Wright et al., 2020).…”

Intelligent Characterization of Lentil Genetic Resources: Evolutionary History, Genetic Diversity of Germplasm, and the Need for Well‐Represented Collections

The genetic and phenotypic characterization of crops allows us to elucidate their evolutionary and domestication history, the genetic basis of important traits, and the use of variation present in landraces and wild relatives to enhance resilience. In this context, we aim to provide an overview of the main genetic resources developed for lentil and their main outcomes, and to suggest protocols for continued work on this important crop. Lens culinaris is the third-mostimportant cool-season grain and its use is increasing as a quick-cooking, nutritious, plant-based source of protein. L. culinaris was domesticated in the Fertile Crescent, and six additional wild taxa (L. orientalis, L. tomentosus, L. odemensis, L. lamottei, L. ervoides, and L. nigricans) are recognized. Numerous genetic diversity studies have shown that wild relatives present high levels of genetic variation and provide a reservoir of alleles that can be used for breeding programs. Furthermore, the integration of genetics/genomics and breeding techniques has resulted in identification of quantitative trait loci and genes related to attributes of interest. Genetic maps, massive genotyping, marker-assisted selection, and genomic selection are some of the genetic resources generated and applied in lentil. In addition, despite its size (∼4 Gbp) and complexity, the L. culinaris genome has been assembled, allowing a deeper understanding of its architecture. Still, major knowledge gaps exist in lentil, and a deeper understanding and characterization of germplasm resources, including wild relatives, is critical to lentil breeding and improvement.
