Lens nigricans

Common NameL. nigricans
AbbreviationL. nigricans

Lens nigricans is a wild relative of Lens culinaris. L. nigricans has stipules that are considerably semi-hastate and dentate at their base1. This species can be divided into two groups based on the orientation of their stipules. Those accessions with upright stipules are usually found in gravelly soil in southern Spain, southern Italy and along the Adriatic coast of Yugoslavia, as well as in man-made habitats throughout southern Europe; whereas, those accessions with horizontal stipules were found on calcereous or basaltic soil in stony and gravelly habitats in Israel and Turkey1. Recent sequence analysis indicates that Lens nigricans is in the quaternary gene pool of L. culinaris2

Lentil seed is a good source of phenolic compounds, which can have health benefits. This project will try to find how different seed coat colours in lentil can be related to the phenolics profile. A fast extraction method and an optimized LC-MS analysis were applied to compare green, gray, tan, and brown seed coat colour lentils. Also, the so called zero-tannin genotypes were compared with the normal ones based upon their phenolic profile. The effect of storage on phenolic profile of lentil seeds was investigated, as well.
Lentil has been grown commercially in western Canada since 1970. Ascochyta lentis, the causal agent of ascochyta blight of lentil is established as one of the most economically important diseases of lentil in Western Canada. To deal with this problem, the widely acceptable genetic improvement strategy is to pyramid resistance genes. Developing closely linked single nucleotide polymorphism (SNP) markers for resistance genes is prerequisite for pyramiding resistance genes. To develop SNP markers, a series of selected recombinant inbred line (RIL) populations derived from resistant sources will be phenotyped under greenhouse conditions (pathogenicity tests) followed by screening available SNP markers across the entire set of RIL populations.
