“…In general, the observed effect of the sowing date on lentil yield in the Spanish meseta agrees with previous studies in which an earlier sowing date increases lentil yield, both in Mediterranean climate zones (Fagnano et al, 1998;Siddique et al, 1998;Chen et al, 2006), or in other climates (Kusmenoglu & Aydin, 1995;Hamdi et al, 1996;Muehlbauer & McPhee, 2002;Sarker et al, 2009). But, according to our results, this effect would depend on the genotypes considered.…”

Lentil (Lens culinaris Medik. subsp. culinaris) is a traditional crop in Spain although current grain yield in Spain is relatively low and unstable. The effect of an early sowing date (winter sowing) on yield in the Spanish Central Plateau (meseta) was analyzed comparing it to the traditional spring sowing. Yield from eleven cultivars currently available for sowing in Spain and two F6:7 populations of recombinant inbred lines (RIL), ´Precoz´ × ´WA8649041´ (89 lines) and ´BGE016365´ × ´ILL1918´ (118 lines), was evaluated in winter and spring sowing dates for three seasons (2005/06, 2006/07 and 2007/08) and two localities. Yield and stability were assessed by the method of consistency of performance with some modifications. When comparing with the best currently available cultivars sown in the traditional spring sowing date, (with an estimated average yield of 43.9 g/m in our experimental conditions), winter sowing using adapted breeding lines proved to be a suitable strategy for increasing lentil yield and yield stability in the Spanish meseta, with an average yield increase of 111% (reaching an estimated yield of 92.8 g/m). Results point to that lentil production can greatly increase in the Spanish meseta if adequate plant materials, such as some of the lines analyzed, are sown at late fall.

“…In lentil, as in faba bean, sources of winter hardiness were associated with high-altitude locations and come from within the cultivated species, rather than from wild relatives (Hamdi et al, 1996). Varieties with winter-hardiness (such as Kafcas, Cifci and Uzbek) are now being cultivated in Turkey.…”

The adaptability and productivity of cool-season food legumes (chickpea, faba bean, lentil, pea) are limited by major abiotic stresses including drought, heat, frost, chilling, waterlogging, salinity and mineral toxicities. The severity of these stresses is unpredictable in field experiments, so field trials are increasingly supplemented with controlledenvironment testing and physiological screening. For drought testing, irrigation is used in dry fields and rain-out shelters in damp ones. Carbon isotope discrimination ( 13 C) is a well-established screen for drought tolerance in C3 cereal crops which is now being validated for use in grain legumes, but it is relatively expensive per sample and more economical methods include stomatal conductance and canopy temperature. Chickpea lines ICC4958 and FLIP87-59C and faba bean line ILB938 have demonstrated good drought tolerance parameters in different experiments. For frost tolerance, an efficient controlled-environment procedure involves exposing hardened pot-grown plants to subzero temperatures. Faba beans Cote d'Or and BPL4628 as well as lentil ILL5865 have demonstrated good freezing tolerance in such tests. Chilling-tolerance tests are more commonly conducted in the field and lentil line ILL1878 as well as derivatives of interspecific crosses between chickpea and its wild relatives have repeatedly shown good results. The timing of chilling is particularly important as temperatures which are not lethal to the plant can greatly disrupt fertilization of flowers. Salinity response can be determined using hydroponic methods with a sand or gravel substrate and rapid, efficient scoring is based on leaf symptoms. Many lines of chickpea, faba bean and lentil have shown good salinity tolerance in a single article but none has become a benchmark. Waterlogging tolerance can be evaluated using paired hydroponic systems, one oxygenated and the other de-oxygenated. The development of lysigenous cavities or aerenchyma in roots, common in warm-season legumes, is reported in pea and lentil but is not well established in chickpea or faba bean. Many stresses are associated with oxidative damage leading to changes in chlorophyll fluorescence, membrane stability and peroxidase levels. An additional factor relevant to the legumes is the response of the symbiotic nitrogen-fixing bacteria to the stress.

Lentils play a major role in the food and nutritional security of millions, particularly among lowincome Asian families, because of the high protein content of their seed. As is the case for many pulses, lentils play an important role as a rotation crop, enhancing soil fertility and providing other environmental services in production systems. While its production has risen globally at 8.6 kg/ ha/year from 1961 to 2008, the major challenge is to increase investment in lentil improvement (both research and outreach) in countries where the crop is part of the production system. Where currently grown the major abiotic stresses are low moisture availability and high temperatures in spring, and winter cold at high elevations. Among biotic stresses, rust, and vascular wilt are key, and resistance has resulted in improvements in performance. Additional production constraints include the agronomic problems of pod loss, lodging and poor crop management. Adequate variability for most genetic constraints exists within the gene pool allowing breeding. However, several key traits, such as biomass yield, pod shed, nitrogen fixation and resistance to aphids are not currently addressable by breeding because of insufficient variation. Among lentil-producing developing countries, policies have not yet focused on lentil development needs to enhance food security and provide a remunerative rotation crop for cereals. Looking towards a future in which there is likely to be less water available to agriculture, climate change, food insecurity, rising costs for inorganic nitrogen fertilizer, and an increasingly nutrition-conscious society-collectively these give a bright future for a highly nutritious food produced by a nitrogenfixing crop such as lentil adapted to the farming systems of marginal lands.
