“…This study was not designed to include the farming system as a source of variation; however, our results demonstrated that SY was affected by the farming system. These results were also confirmed in previous studies [ 42 , 43 , 44 ] although genotypic response within farming system was not thoroughly studied. Under organic farming conditions and across the five lentil genotypes, the most productive environment was E8 (2.28 t ha −1 ) which corresponded to location Orestiada/2020, followed by E3 (1.88 t ha −1 ) (Thessaloniki/2019) and E4 (1.87 t ha −1 ) (Orestiada/2019).…”

Lentil is an important legume crop for human and animal dietary needs due to its high nutritional value. The effect of genotype and growing environment was studied on seed yield (SY), crude protein (CP) and mineral nutrients (macro and micronutrients) of five lentil genotypes grown at four diverse locations for two consecutive years under organic and conventional farming. The location within each year was considered as a separate environment (E). Data were subjected to over environment two-way analysis of variance, while a genotype (G) plus genotype × environment (GGE) biplot analysis was performed. Our results indicated the E as the main source of variation (62.3–99.8%) for SY, CP and macronutrients for both farming systems, while for micronutrients it was either the E or the G × E interaction. Different environments were identified as ideal for the parameters studied: E6 (Larissa/Central Greece/2020) produced the higher CP values (organic: 32.0%, conventional: 27.5%) and showed the highest discriminating ability that was attributed to the lowest precipitation during the crucial period of pod filling. E7 (Thessaloniki/Central Macedonia/2020) and E8 (Orestiada/Thrace/2020) had fertile soils and ample soil moisture and were the most discriminating for high micronutrient content under both farming systems. Location Orestiada showed the highest SY for both organic (1.87–2.28 t ha−1) and conventional farming (1.56–2.89 t ha−1) regardless the year of cultivation and is proposed as an ideal location for lentil cultivation or for breeding for high SY. Genotypes explained a low percentage of the total variability; however, two promising genotypes were identified. Cultivar “Samos” demonstrated a wide adaptation capacity exhibiting stable and high SY under both organic and conventional farming, while the red lentil population “03-24L” showed very high level of seed CP, Fe and Mn contents regardless E or farming system. This genetic material could be further exploited as parental material aiming to develop lentil varieties that could be utilized as “functional” food or consist of a significant feed ingredient.

“…Valuable genotypic variability was observed with respect to both seed and yield losses. Farming system was the main source of variation for both losses, while early flowering and small seed size were traits associated with low losses (Vlachostergios et al 2018). Lentil yield loss from the competition with weeds can range as high as 80% (Pala 2019).…”

Genomic Designing for Biotic Stress Resistant Pulse Crops

Lentils are already one of the main pulses of the world, as they are one of the main sources of protein for humans. As a crop, they are also gaining momentum because the rusticity and tolerance to water scarcity of some varieties are a good fit with the current global warming trend and climate change in general. However, while the harvested area and overall production have drastically increased over the last decades, yield has only experienced very modest increments. The reasons are two-fold. First, pathogens are affecting the crop as never before, likely due to not only the changing climate but also to the expansion of lentil cultivation to new geographic areas. Second, genomics-aided breeding is far behind many other crops. This is in partly due to the lack of genomic tools currently available to researchers. Progress is being made to adopt high-throughput genomic methods, and researchers will be able to tackle lentil gene discovery and breeding for pathogen resistance and other biotic stresses more efficiently in the coming years. We outline the current situation, novel findings, and prospects of lentil research for biotic stresses. IntroductionLentil (Lens culinaris Medik. subsp. culinaris) is one of the first domesticated species in the Fertile Crescent and along with barley, emmer wheat and einkorn wheat, pea, chickpea, and flax was part of the set of crops that defined the beginnings of the Neolithic transition to agriculture in this part of the World. The origin of the cultivated form is the wild L. culinaris subsp. orientalis (Boiss.) Ponert (syn. L. orientalis Boiss.). A recent publication by Liber et al. (2021) suggests that phylogenetics, population structure, and archeological data coincide in a lentil domestication prolonged in time in Southwest Asia, with two different domesticated gene pools.

“…Lake and Sadras (2021) found that the selection of lentil genotypes with high growth rates could improve yield under stress. Vlachostergios et al (2018) found that lentils, depending on variety, can adopt two main strategies, that is, fast growth rate or high harvest index (HI), in response to bruchid damage; therefore, these specific traits should be carefully considered when choosing the variety to reduce yield loss. Considering weed control, Pannacci et al (2017Pannacci et al ( , 2018 reported on nonchemical weed management options for minor and legume crops and found that coupling split-hoeing and fingerweeding represents one of the best mechanical weed control options in organic cropping systems.…”

Lentil–cereal intercropping in a Mediterranean area: Yield, pests and weeds

Introducing grain legumes into cereal‐based cropping systems can enhance crop diversification and related factors (e.g., farm N‐self‐sufficiency). Lentil (Lens culinaris Medik.) is a minor grain legume species that offers nutritional and other benefits when incorporated into diets. However, lentil production is often characterized by low and unstable yields due to drought, pests, and high yield losses during mechanical harvest. Intercropping is a promising agroecological‐based strategy that may overcome these drawbacks. Our objective was to determine if intercropping (i) enhanced crop productivity and resource use efficiency, and (ii) suppressed weeds and bruchid insect pest dynamics. To do this, two lentil–cereal intercropping mixtures were compared in central Italy during 2020 and 2021 as follows: (i) lentil + triticale (× Triticosecale Wittm., ‘Forricale’) and (ii) lentil + barley (Hordeum vulgare L., ‘Cometa’). Weed biomass was reduced by 97% because of the competitive ability of the grass component in intercrops compared to a lentil monocrop (p ≤ 0.05). Both intercrops reduced bruchid grain loss by 16% and showed higher efficiency than single pure stand crops (land equivalent ratio >1). Unfortunately, the highly competitive effect of the cereal reduced lentil yield in intercrops by 59% (−40.3 g m−2, on average). Our results indicate that cereals should be planted at low densities, or the spatial arrangement of both species should be modified, to prevent suppression of lentils in intercrops with barley, triticale, and other small‐grain crops.
