Pakistan Journal of Biological Sciences , 2002,
Abstract: Field experiments were conducted during the winter seasons of 1998-1999, and 1999- 2000 in northern Jordan, to study the effect of date and rate of sowing on the yield and yield components of lentil (Lens culinaris Medik.). Progressive delay in sowing beyond 1st December a yield reduction of 20.8 and 40.1 % was recorded with successive delays in sowing at every 20 days interval. Plant height, primary branches plant-1,secondary branches plant-1,number of pods plant-1 and 100-grains weight followed the same trend as yield. Seed yield was not significantly affected by sowing rate.

African Journal of Biotechnology , 2009,
Abstract: This study was carried out in order to determine the effect of seed size on the yield and yield components of chickpea and lentil. Two field experiments, composed of three chickpea (Cicer arietinum L.) varieties, four lentil (Lens culinaris Medik.) and two seed sizes, were conducted in southeastern Anatolia, Turkey in 2005 and 2006 in randomized complete block designs. The seeds of the three grading sizes used in this study were evaluated for yield and its components in chickpea and lentil. For chickpea, effect of seed size on yield and 100 seed weight were significant, but no difference in seed size affects other yield components, and correlations between seed size and seed yield and 100 seed weight were positive. For lentil, effect of seed size on yield and yield components was not significant.

Abstract: Calpún-INIA es un cultivar de lenteja (Lens culinaris Medik.) resistente a la roya (Uromyces fabae Pers.), desarrollado por el ex Programa de Leguminosas de Grano del Instituto Nacional de Investigaciones Agropecuarias (INIA), Chile. Se origina de un cruzamiento entre el cultivar chileno Araucana-INIA susceptible a la roya y el cultivar canadiense Laird resistente a roya, utilizando precocidad, arquitectura de planta del tipo Araucana-INIA, tama o de grano, rendimiento de grano y resistencia a roya como criterios de selección. Calpún-INIA pertenece a los cultivares de tama o de grano grande (tipo macrosperma), con peso promedio de 8 g por 100 granos, y con tama o de grano de 7 mm superior a 65%. La semilla es parcialmente aplanada, de color verde claro a gris y de cotiledones amarillo pálidos. En promedio de temporadas, el rendimiento en grano de Calpún-INIA fue 17% inferior a Araucana-INIA, en evaluaciones realizadas en ambientes libres de roya. En tanto, su rendimiento supera a Araucana-INIA entre 60 a 95%, en ambientes donde la enfermedad es la principal limitante de producción. Calpún-INIA es el primer cultivar de lenteja desarrollado por INIA que combina alto rendimiento y calibre de grano, con resistencia a roya. Calpún-INIA is a rust (Uromyces fabae Pers.) resistant lentil (Lens culinaris Medik.) cultivar that was developed by the former Food Legume Program of the National Institute of Agricultural Research (INIA), Chile. It is derived from crosses between the Chilean rust-susceptible Araucana-INIA and the Canadian rust-resistant Laird cultivars, using earliness, Araucana-INIA’s type of plant architecture, seed size, seed yield and rust resistance as selection criteria. Calpún-INIA belongs to the large seeded cultivars (macrosperma type), averaging 8 g per 100 seeds, and > 65% of seeds retained in a 7 mm sieve. The seed is partially flattened, with pale green to grey background and pale yellow cotyledons. Averaged across years, the seed yield of Calpún-INIA was 17% lower than Araucana-INIA’s in rust-free environments, whereas Calpún-INIA out-yielded Araucana-INIA by 60 to 95% in environments where this disease is the main constraint for lentil production. Calpún-INIA is the first lentil cultivar released by INIA, combining high yield and large seed size with rust resistance.

Abstract: Laboratory tests and two field experiments were conducted in RCB design in 2006 and 2007 at the Research Farm of the University of Tabriz, Iran, to evaluate the effects of hydro and osmo - priming (PEG: Polyethylene glycol 6000 at -0.8MPa ) on seed germination and field emergence of lentil. Analysis of variance for laboratory data showed that hydropriming significantly improved germination rate and root weights, compared to other seed treatments. However germination percentage for seeds primed with water and PEG were statistically similar, but higher than those for unprimed seeds. Over all, hydropriming treatment was comparatively superior in laboratory tests. Invigoration of lentil seeds by hydropriming resulted in higher seedling emergence in the field, compared to control and seed priming with PEG. Seedling emergence rate was also enhanced by priming seed with water. Thus, hydropriming could be used as a simple method for improving seed germination and seedling emergence of lentil in the field.

Abstract: In order to evaluate relationship between Different traits in lentils (lens culinaris Medik), a field study was conducted as an RCBD based design with 3 replications on Zanjan University Research Farm during spring of the year 2004. ANOVA analysis revealed significant differences for all characters except for the number of primery branches. Correlation analysis indicated positive and significant correlation between seed yield and harvest index, number of primery branches, pods/plant and biological yield, and grian yield. The result of the factor analysis also showed that the second factor including number of primery branches, pods/plant, grian yield, canopy width and seeds/plant was an important trait involved in the grian yield in lentil. In addition, cluster analysis helped divide the genotypes into four distance groups of large, medium, semi medium and low yields.

Abstract: Maintenance of high bacterial population in the rhizosphere improves the efficiency of these organisms. This high bacterial population can be maintained by the application of enriched compost which supports their growth and activities. Thus integrated use of Rhizobium, plant growth promoting rhizobacteria (PGPR) containing 1-aminocyclopropane-1-carboxylate deaminase (ACC-deaminase) and P-enriched compost (PEC) could be highly effective for promoting growth, nodulation, and yield of lentil (Lens culinaris Medik.). A field study was conducted to evaluate the potential of Rhizobium, PGPR containing ACC-deaminase and PEC for promoting growth of lentil. For this study, the soil type was sandy clay loam soil having pH 7.6; EC (electrical conductivity) 2.8 dS m-1; organic matter (OM) 0.59%; total N 0.032%; available P 7.9 mg kg-1, and extractable K 129 mg kg-1. Treatments were replicated thrice, using randomized complete block (RCB) design.

Abstract: Understanding the genetic relationships and diversity of Ethiopian lentil in relation to lentil from other countries is important in attempting to widen the genetic base of germplasm in the country. The objectives of this study were to generate information on agromorphological variability, to estimate PCV, GCV, heritability, and expected genetic advance of quantitative traits of lentil. 228 genotypes with different population types were studied for 11 agromorphological traits and rust disease severity score for two seasons (2011-2012) over three locations. The analysis of variance showed highly significant variations ( ) among genotypes for all characters studied. As per genetic parameter values, four groups of character were deduced. It is inferred that the exotic genotypes introduced from ICARDA showed rich genetic bases for 100-seed weight, number of seeds per plant, seed weight per plant, resistance source for rust, and high yielder in high yielding environment, where rainfall is not a major problem. Use the Ethiopian accessions for developing cultivars that could be used in double cropping and drought prone areas. 1. Introduction Lentil (Lens culinaris Medik. subsp. culinaris) is a short, slender annual cool-season food legume. The center of origin of lentil is the Near East where it was first domesticated in the Fertile Crescent around 7000 BC [1]. According to Barulina [2], two varietal types based on seed size were recognized: the small-seeded microsperma and the macrosperma with relatively large flattened pods. The largest lentil producer is India, followed by Canada and Turkey, accounting for 68% of the global production [3]. In Africa, Ethiopia, Morocco, and Tunisia are the leading producers, but 61% of the areas and 68% of the production belong to Ethiopia [4]. Lentil is an important dietary source of macro- and micronutrients for both rural and urban dwellers. It provides sufficient amounts of the most essential amino acids to meet nutrient requirements. It is a cash crop fetching the highest price in domestic market compared to all other food legumes and major cereal crops [5]. Global, African, and Ethiopian lentil productivity is about 887?kg/ha, 644?kg/ha [3], and 1168?kg/ha, respectively [6]. Biotic and abiotic factors limit lentil productivity and seed quality. The major yield gap contributing factors are insect pests, diseases, low yielding landraces grown by farmers, and the narrow genetic base [7, 8]. Prior knowledge of genetic variability and characterization of genetic resources within the germplasm available at a gene bank has an
