“…), chickpea (Cicer arietinum L.), faba bean (Vicia faba L.), pea (Pisum sativum L.), and lupin (Lupinus spp.) are infected naturally by more than 70 different viruses worldwide, and the number of viruses involved continues to increase (Boiteux, de Avila, Giordano, Lima, & Kitajima, 1995;Bos, Hampton, & Makkouk, 1988;Hampton, 1984;Jones & McLean, 1989;Kumar, Kumari, & Waliyar, 2008;Kumari, Larsen, Makkouk, & Bashir, 2009;Makkouk, 1994;Makkouk, Kumari, Hughes, Muniyappa, & Kulkarni, 2003;Makkouk, Pappu, & Kumari, 2012;Schwinghamer, Johnstone, & Johnston-Lord, 1999;Schwinghamer, Thomas, Parry, Schilg, & Dann, 2007;Thomas, Parry, Schwinghamer, & Dann, 2010;Thomas et al, 2004).

“…These accessions will be useful in developing lentil cultivars with virus resistance. The use of host resistance and one or two well-timed insecticide applications coupled with optimal planting date and early roguing of virus-infected plants offers reasonable and economic virus disease control (Kumari et al 2009). …”

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.

“…For example, more than 50 fungal pathogens have been reported to be seed-borne in rice (Oryza saliva L.) [10] among which 14 are of major importance [11]. Five out of the 26 viruses known to affect lentil (Lens culinaris L.) are also seed-borne [12]. Seed maintained by farmers carry seed-borne pathogens that reduce germination rate and transmit pathogens to plants, causing enormous crop losses [11,13].…”

Landraces are heterogeneous populations and their variability goes through continuous alterations because of physical, genetic, and epigenetic procedures exacerbated by the ongoing climatic changes. Appropriate stewardship of landrace diversity is pivotal to promote its longevity in a manner that is sustainable from the farming perspective. A seed multiplication procedure is presented based on the assumption that in order to improve effectiveness in resource use and increase seed productivity, landraces should comprise genotypes which minimize intra-species competition. These aforementioned genotypes should be of the "weak competitor" ideotype, which are selected so as to alleviate the interplant competition and reach as high as possible crop stand uniformity. Stand uniformity is essential to ensure the same growing conditions for each plant. Reduced intra-crop inequality and equal use of inputs by individual plants will optimize crop performance. Precisely, the "weak competitor" is most often of high yield potential due to a negative association between yielding and competitive ability. Therefore, the suggested procedure involves initial reproduction at nil-competition (widely spaced plants to preclude any plant-to-plant interference for inputs) where "off-type" and low yielding plants are omitted, followed by subsequent multiplication at dense stands. This may represent an effective cultural practice to improve also the landrace health status concerning seed-borne diseases in the absence of certification systems.
