Tracing domestication traits (shattering) in an interspecific lentil population: LR-86

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 for shattering resistance were identified on LGs 4 and 7. In 2017, the population was grown in two locations (Investigation field and Sutherland) in three replications to confirm the identified QTL for shattering resistance.
