“…The top ten lentil producing countries, namely Canada, India, Australia, Turkey, United States of America, Nepal, Kazakhstan, Bangladesh, Russian Federation, and China, collectively produced more than 92% of global output (FAOSTAT 2021). With rising interest in plant-based protein among health-conscious people, the gap between demand and supply of protein-rich lentils is increasing (Rubiales et al 2021). To bridge this gap, there is a dire need to increase the productivity per unit area by adopting improved varieties and crop management practices.…”

Context Yield losses in lentil (Lens culinaris ssp. culinaris Medik.) caused by weeds are estimated at 20–80%. In the absence of effective broad-spectrum herbicides, the menace of weed has emerged as a serious yield constraint in lentil. Aims Identification of tolerance to two broad-spectrum post-emergence herbicides, imazethapyr and metribuzin. Methods 221 lentil accessions were screened at the experimental research station of the International Center for Agricultural Research in the Dry Areas, Terbol (Lebanon) over four crop seasons (2014/15–2018/19). During the 2014/15 season, a preliminary screening experiment was conducted with 221 lentil accessions in an alpha lattice design with two replications, where accessions were treated at the pre-flowering stage at 150% of the recommended dose of imazethapyr (112.5 g active ingredient/ha) or metribuzin (315 g active ingredient/ha). Based on the preliminary results, 38 accessions were selected for further evaluation. In subsequent testing, the selected accessions were screened at 100% and 150% of the recommended doses of imazethapyr or metribuzin. Key results Herbicide treatments delayed the flowering time and maturation of tested lentil accessions. The plant height of selected tolerant accessions was reduced by 15% and 8% in the plots treated by imazethapyr and metribuzin, respectively. Reduction index (RIsy) was an effective tool to select for herbicide tolerance. Stability analysis indicated that two accessions (IG4400 and IG5722) performed under high rainfall environments while two other accessions (IG323 and IG4605) were adapted to low rainfall environments. Conclusions Four accessions (IG323, IG5722, IG4400, IG4605) were identified as independently tolerant to metribuzin and imazethapyr. Implications The identified herbicide-tolerant accessions can be used to develop herbicide-tolerant cultivars.

“…The increasing demand for environmental-friendly agricultural practices and food security establishes a favourable context for new cropping systems that include grain and forage legumes [5,6]. Grain legumes, also known as pulses, are major foodstuffs and important sources of protein in most countries [7].…”

Grass pea (Lathyrus sativus L.) is an annual cool-season grain legume widely cultivated in South Asia, Sub-Saharan Africa, and in the Mediterranean region. It is a stress-resilient crop with high nutritional value, considered a promising source of traits to breed for adaptation/mitigation of climate change effects. It is also reported as a suitable crop for more sustainable production systems such as intercropping. In this review, we elaborate an integrative perspective including not only an agronomic-based but also a variety-breeding-based strategy in grass pea to deal with climate change impacts, summarizing the current knowledge on grass pea biotic/abiotic stress resistance. Additionally, we highlight the importance of implementing fundamental techniques to create diversity (as interspecific hybridization or gene editing) and increase genetic gains (as speed breeding or the efficient identification of breeding targets via genomics) in the development of multiple stress-resistant varieties that simultaneously provide yield and quality stability under climate vulnerable environments.

“…Legumes (species belonging to the family Fabaceae) are indispensable for the transition to an environmentally and economically sustainable agri-food system (Rubiales et al 2021). This is due to their symbiosis with nitrogen-fixing bacteria, which strongly reduces the need for application of synthetic N fertilizer, and thus reduces energy-demanding fertilizer production.…”

“…Moreover, legumes are rich in protein, a limited resource in many parts of the world (de Visser et al 2014;Gale et al 2015). Compared to crops of the grass family (Poaceae), the efforts to produce genetically improved legume varieties through plant breeding has been limited so far (Rubiales et al 2021). However, the current focus on sustainable agriculture, protein crops and plant-based food has stirred an increased interest from both farmers and plant breeding companies.…”

Breeding for intercropping: the case of red clover persistence in grasslands

Legumes are important in sustainable agriculture and particularly so when they are intercropped with other species. In breeding programs, little attention is paid to their agronomic performance in species mixtures. In red clover, improved persistence is an important breeding goal. We identified traits associated with survival of red clover cultivated in pure stands (PS 3) or in mixtures with grasses (MS 3) and managed under a 3-cut system (two locations), as well as in pure stands in a 5-cut system (PS 5, one location). Survivors from replicate plots were collected and a new generation made from each plot. The new generations were characterized in a growth experiment with light or simulated shade, and in a freezing experiment. We show that the traits related to red clover persistence depend on both plant community composition and cutting frequency. MS 3 had more leaves with larger leaf blades and longer petioles during the vegetative stage, followed by earlier stem elongation, higher number of elongating stems, higher biomass (also when accounting for earlier stem elongation) and more leaves in the regrowth after cutting than PS 3. MS 3 also had better freezing tolerance. PS 5 was similar to MS 3 and different from PS 3 in the number of leaves, leaf blade size, petiole length and number of elongating stems. These results show that breeding and cultivar evaluation, which is currently almost exclusively considering performance in pure stands, may miss some variation which provides persistence of red clover in mixtures with grasses.
