Lentil is a notable legume crop valued for its high protein, vitamin, mineral, and amino acid (lysine and tryptophan) content. This crop has a narrow genetic base due to the formation of gene pool barriers during interspecific hybridization within and across species. Mutagenesis may be seen as a novel and alternative breeding technique for the production of new diversity. For the identification of new alleles, the creation of mutants followed by selection in subsequent generations would be necessary. Induction of mutation in lentil cv. Moitree by gamma rays therefore produced high variation for the majority of quantitative measures examined. Henceforth, principal component analysis (PCA) and path coefficient analysis were conducted to identify and exclude redundant mutant genotypes with similar traits as the success of breeding is dependent on understanding the relationship between morpho-agronomic traits and seed yield. As shown by the findings of this research, the total quantity of pods per mutant plant should be given considerable priority. The identified mutant genotypes, such as lines 24, 43, 28, 33, and 10, may be used as parents in future breeding or released directly following trials.
... It is crucial for human and animal nutrition, as well as improving soil health. Lentil seed is a rich source of protein (third-highest after soybean and hemp), soluble and insoluble fibre, minerals (K, Ca, Zn, Fe, P) and vitamins (thiamine, niacin and riboflavin) for balanced human nutrition [3,4]. Furthermore, due to its high lysine and tryptophan content, its consumption with cereals provides the perfect complementary amino acid profile for human consumption. ...

Knowledge of genetic diversity in lentil is imperative for selection of parental genotypes that could yield heterotic combinations. The aim of the present study was to investigate the genetic diversity among 43 diverse lentil genotypes to identify complementary and unique genotypes for breeding programmes. Field experimentation was carried out in two winter seasons (2019–2020 and 2020–2021) in Hisar (29°10′ N, 75°46′ E) using randomized block design (RBD) with three replications. The chi-square test analysis showed significant genotypic variation for qualitative traits. There was substantial genetic variation among the genotypes for most quantitative traits, connoting the need to exploit a high degree of genetic variation through selection. Multiple-trait selection would also be beneficial, as seed yield was positively associated with most quantitative traits. The principal component analysis recognized seed yield (SY), days to 50% flowering (DTF), days to maturity (DTM), number of pods per plant (NPP), number of primary branches (NPB), plant height (PH) and biological yield (BY) as target traits that prominently described variation within lentil genotypes. The cluster analysis discriminated the lentil genotypes into five discrete clusters. Cluster III and V were the most distant groups, implying wider diversity among the genotypes of these groups. Furthermore, cluster analysis identified genotypes IPL 316, LH 17-19, LH 18-04, LH 17-17, IPL 81 and Pant L-8 as high-yielding genotypes, while L 4717 was identified as an early-maturing genotype. Therefore, to obtain a broad spectrum of early-maturing high-yielding segregants, the selected genotypes may serve as superior parental lines for structuring breeding strategies.
... Although domesticated in the Fertile Crescent in the Mediterranean environments, it has spread globally in successful cultivation in sub-tropical, temperate, and non-tropical dry environments including South Asia, Sub-Saharan Africa and North Africa, Europe, Latin America, North America and Oceania. Since its seed contains high levels of protein (up to 33%), macronutrients (Fe and Zn), and vitamins (β-Carotene, thiamin, niacin, folic acid) (Bhatty, 1988;Savage, 1988), it provides nutritional security for the people in the developing countries where poor consumers cannot afford costly animal products. Lentil straw is used as animal feed (Erskine el al., 1990a), and serves as an additional source of income. ...

Lentil (Lens culinaris Medik. culinaris) is an important pulse crop causative to nutrition and food security of people in Afghanistan. Genotype by environment interaction (GEI) is one of the major factors restraining the efficiency of any breeding program. This study consisted of two lentil yield trials conducted in alpha design with two or three replicates at three locations for two years (2014-2015 and 2015-2016). Genotypic differences were significant (P<0.05) in all the environments. Genotype × location interactions were found significant (P<0.01) in each year for LIEN-LS and LIEN-SS trials. There were significant genotype × year interactions of crossover type. For LIEN-LS genetic materials, Herat and Mazar formed a mega-environment based on responses in 2015 and 2016. High yielding genotypes with specific adaptation to Mazar and Herat environment were LG16 (FLIP2012-21L) in 2015 and LG24 (FLIP2013-3L) in 2016, whereas LG30 (FLIP2013-20L) was identified as high yielding with specific adaptation to Nangarhar environment during both the years. The high yielding genotypes in 2015 were LG32 (FLIP2013-29L) at Herat, LG16 (FLIP2012-21L) at Mazar and LG30 (FLIP2013-20L) at Nangarhar from LIEN-LS. In 2016, LG12 (FLIP2013-16L) at Herat, LG5 (FLIP2013-3L) at Mazar and LG1 (FLIP2013-20L) at Nangarhar were identified as high yielding genotypes. In 2015-16, SG12 (FLIP 2013-51L) at Herat, SG2 (FLIP2013-59L) at Mazar and SG6 (FLIP2013-66L) at Nangarhar were the top yielding genotypes from LIEN-SS. The identified genotypes from LIEN-LS and LIEN-SS at the two locations (Mazar and Nangarhar) may be used for up-scaling lentil production to support food security in Afghanistan as well as for generating new genotypes using crossing-selection-evaluation cycle.

A field trial with fifty genotypes of lentil was undertaken in Agriculture Farm of the Institute of Agriculture, Visva-Bharati University during two consecutive winters of the year 2017-18 and 2018-19, with an intention to find out the nature of the association between thirteen different plant characters with each other and with yield. A randomized block design was used with three replications. Traits' correlation along with path analysis was studied by focusing on yield as the key output. The study revealed that seed/plant was strong and positively associated with grain yield at the genotypic level. It was also true at the phenotypic level. Direct and indirect effects in path coefficient at genotypic and phenotypic level revealed the effects of various traits on yield either directly or via component traits. In the present experimental study, fourteen character combinations of lentil explained that total variance up to 82.74 per cent at the phenotypic level and 82.23 per cent at the genotypic level.

Inoculation with effective Rhizobium strains is an essential practice that helps the plant to fix atmospheric nitrogen symbiotically and stimulates the growth of plants and ultimately leads to better produce. In this present study, the Rhizobium strains were isolated from the root nodules of lentil plants form Murshidabad district of West Bengal, using Yeast Extract Mannitol Agar (YEMA) medium. Based on different biochemical tests and growth on YEMA medium, 5 isolates were selected and a pot experiment was carried to study the effect of those selected Rhizobium strains on plant growth and root nodulation. Inoculation with Rhizobium strains resulted in better growth and nodulation over un-inoculated control. Among the five strains, T 1 strain recorded the highest plant height, maximum number of primary and secondary branches, number of nodules and number of pods compared to other strains.

Lentil (Lens culinaris) is a very important nutritious crop, grown, consumed throughout the world due to its high macro and micronutrients contents, including all the minerals. The nutritive components of lentil have several beneficial influences on human health. The current review aims to highlight the present knowledge on the mineral, amino acid, lipids, vitamins and carbohydrate composition of lentils. Thereby, a literature search was conducted using reliable sources: Elsevier, Research gate, Springer, etc to understand the overall nutritive status of lentils. The proximate composition of lentils is similar when compared with other legumes but the seed contains low concentrations of fat, fiber. Lentils supply a reasonably balanced range of all minerals. Lentils contain a number of anti-nutritive factors and these may be controlled either by processing or possibly by plant breeding programs. Anti-nutritive factors are less important In human diets because of cooking and processing which normally occur prior to eating, Lentils have a potential as a protein concentrate and could be processed to produce many products similar to those produced from soya beans. Lentils should be used for a variety of purposes, mainly towards eliminating malnutrition, on the condition of being well-balanced. Lentils should be incorporated either in snacks or while preparing household, school, or hospital meals, particularly in developing countries.
Thesis
Afin d’évaluer la qualité alimentaire et l’efficacité métabolique des aliments mixtes combinant différentes sources protéiques végétales ou des sources protéiques végétales/animales, deux aliments de base, les pâtes alimentaires et les gels laitiers, ont été choisis comme vecteurs et ont été enrichis par des farines ou des protéines de légumineuses. La structure de la fraction protéique des aliments mixtes a été étudiée à l’échelle moléculaire. La relation entre cette structure et la digestibilité in vitro et in vivo des protéines a été évaluée. L’effet de la formulation et/ou du procédé de fabrication de ces aliments mixtes sur le métabolisme protéique in vivo a été étudié chez des rats jeunes en croissance et des rats âgés. Le changement de la formulation des pâtes alimentaires, c'est à dire l’incorporation de trois farines de légumineuses différentes (féverole, lentille ou pois cassé), génère des modifications de structure du réseau protéique influençant la digestibilité des protéines. Les études animales montrent que la qualité alimentaire des pâtes enrichies en légumineuses est comparable à celle d’une protéine animale comme la caséine et ce, quel que soit le type de légumineuses utilisé. La rétention protéique corporelle et la synthèse protéique musculaire des rats âgés, consommant des régimes iso- protéiques à base de pâtes alimentaires enrichies en légumineuses ou de caséine, sont comparables. Elles restent cependant inférieures à celles induites par les protéines solubles du lait. L’utilisation de gels laitiers enrichis en protéines de féverole chez le rat a révélé un effet de la formulation et du procédé de gélification sur la digestion et la rétention protéiques. La digestibilité in vivo des protéines est plus élevée chez les rats consommant le régime contenant le gel fermenté mixte composé de protéines de caséine et de féverole comparativement à son homologue de même composition mais acidifié par voie chimique. La rétention protéique est encore améliorée chez les rats ayant consommé le régime contenant le gel fermenté composé de protéines de caséine, de féverole et de lactosérum. Ces aliments enrichis en légumineuses, riches en protéines, équilibrés en acides aminés indispensables commencent à être disponibles sur le marché. Ils pourraient être proposés à la population âgée notamment dans des situations physiopathologiques impliquant une perte de protéines corporelles.

Lentil (Lens culinaris Medik) grains are considered as dietary source of proteins, minerals and antioxidants mainly in developing countries. Thus, the interest combining nutritional quality with high productivity in releasing novel varieties. In this context, current study aims on assessing genetic potential of 40 genotypes. A total of four morphological traits and two nutrient components were used. Recorded data were analyzed for ANOVA and a hierarchical cluster was built on the basis of Jaccard similarity and dissimilarity index. Studied genotypes have exhibited significant variability for most of measured traits. The nutritional and morphological analysis showed that some genotypes were excellent sources of proteins, iron and had good productivity. Four clusters have been identified at 78% of similarity. The first cluster grouped twenty-two genotypes characterized with booth high yield and high protein content. The second cluster grouped some genotypes with high protein levels whereas third Cluster gathers genotypes with high productivity. However, cluster IV regrouped genotypes with low yield potential and low protein contents, but high iron levels. Among the first cluster, genotypes V9 and Ad8 might be a promised novel variety.

The objectives of this study were to investigate the effects of different harvesting times (early, on-time and late harvest) and lentil varieties (DR13127, Sakar, Kafkas, Bukun, Firat-87, Cagıl) on protein content (PC) and mineral nutritional values of some lentil cultivars seeds and determine the correlations between PC and mineral concentrations, and between minerals concentrations themselves. The results of the study indicated that while the late harvesting increased the potassium (K) and calcium (Ca) concentrations of lentil seed, magnesium (Mg), sodium (Na), and nickel (Ni) concentrations were higher in early harvesting than other two harvesting times. There was significant difference among genotypes for the Ca, Mg, zinc (Zn), Na, copper (Cu), manganese (Mn), and Ni concentrations in seed. It was found that the varieties had no statistically significant effect on PC, K, iron (Fe) and selenium (Se) content of the seeds. It was found that the varieties had statistically significant effects at the level of p ≤ 0.01 on Ca, Mn, and Ni content of the seeds, at the level of p ≤ 0.05 on Mg and Na content of the seeds, and at the level of p ≤ 0.1 on Zn and Cu content of the seeds. Also, the significant correlations between mineral concentrations and PC and mineral concentrations were found in this study. Consequently, it can be said that the harvesting time and variety is critical for some mineral nutrient values of lentil seed. Information obtained from this study will be useful for lentil producers, breeders, processors and marketers.
