Tracing domestication traits (shattering and plant growth habit) in an interspecific lentil population: LR-70

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 in wild and cultivated lentils. This population is being grown at the Investigation field in a single replication and at the Crops Sciences Field Lab in pots in three replications in 2017. Days to emergence, percentage emergence, days to flowering, days to maturity, plant height at maturity, plant architecture on the scale of 1-3 (1 = Prostrate, 2= Semi erect, 3= erect) will be recorded. This population has been genotyped and mapped using a genotyping-by-sequencing approach. QTLs underlying this trait will be identified followed by markers or candidate genes linked to these important agronomic and domestication traits.
