    Today, superior Canadian lentil cultivars are expected to grow well in our northern growing conditions while being resilient to various abiotic and biotic stresses.  The breeders achieve this by using diverse materials in their crosses, but need to ensure that offspring from these crosses can flower and mature at the right time in Saskatchewan. If we could predict flowering and maturity traits in lentil effectively using genetic markers, we will then be able to devote more... read more

Measuring biomass (above ground plant material biomass) in 6 varieties (ILL 7716, CDC Astrix, PI 490288 LSP, CDC Redcoat, CDC Cherry, ILL 9888) with a sample (micro plot -3 replicates) taken every two weeks. To correlate biomass with a volume estimate from UAV images.

An Illumina Golden Gate array was developed using SNPs identified as part of the Common Bean 454 Sequencing & Genotyping Project.

This project contains phenotypes taken opportunistically during RIL Development of LR-68. Only orphan data taken during RIL development should be included in this project It should not include data taken as part of a graduate student project or data taken to answer a specific question.

Growth habit is one of the most significant agronomic traits involved in the domestication process. Growth habit in lentil breeding encompasses alterations related to plant structure affecting production and yield stability. This population, Eston (L. culinaris) x IG 72623 (L. odemensis), is being evaluated to investigate the genetic and phenotypic variability for agronomic and growth habit and to identify the molecular mechanisms underlying the quantitative variation for these traits... read more

A diverse collection of lentil accessions is being phenotyped for days to flower and screened against potential flowering time genes Identified by other researcher groups. In addition to the confirmation and the development of markers useful for the prediction of flowering time in northern temperate (Sask.) conditions, the identification of other candidate flowering time genes are goals of this project.

Lentil recombinant inbred lines (LR-86) derived from a cross between Lupa # 7 (L. culinaris) x BGE016880 (L. orientalis) were evaluated in five replications in 2016 in the field at the Crop Science Field Lab of the University of Saskatchewan. Days to flowering, days to maturity, plant height at maturity, shattering percentage, number of seeds per plant, and seed yield per plant were recorded. The population was genotyped and mapped using a genotyping-by-sequencing approach. Major QTLs... read more

In the food industry, seeds which are used whole – like peas, dry beans, and soybeans – need to have a good hydration capacity, or the ability to absorb water, in order to be desired by consumers. Seeds that do not absorb water are called stone seeds / hard seeds and are considered a negative seed quality characteristic because they must be removed before processing. Cultivars that are known to have large amounts of stone seeds are seen as wasteful by canners and will be... read more

This research project aims to efficiently expand the genetic diversity of the Canadian lentil breeding program. Targeted-exome resequencing of the AGILE lentil diversity panel will provide the information needed to determine which germplasm can provide that genetic diversity, as well as, be used to develop markers to efficiently select against poor adaptation.

Cultivated lentil is a quantitative long day plant. In-season temperature and daylength varies considerably among three main growing regions, which are northern temperate regions (SK, North Dakota), Mediterranean climates (Turkey, Spain, Morocco), and South Asian (India, Bangladesh, Nepal). Different temperature and daylength among the regions lead to different plant life cycle. In northern temperate regions, sowing is between April to May when days are... read more
