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, IG 72643 (L. orientalis) x 3339-3 (L. culinaris), is being evaluated to investigate the genetic and phenotypic variability for agronomic and growth habit and to identify the... read more

    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 Asterix, 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

 

Light is essential for plant growth and development. Green plants selectively absorb blue and red wavelengths of the light, which resulted in a decrease in red/far-red (R/FR) ratio in the surrounding environment. The reduction is sensed by the plants, thereby signaling the presence of neighboring plants/weeds as potential competition, which would lead to enhanced stem elongation and accelerated transition to flowering. However, for crop species, this could lead to... read more
