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

Overview
2016

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.

Breeding & Genetics

Plant breeding is the art and science of changing the traits of plants in order to produce desired characteristics. Plant breeding can be accomplished through many different techniques ranging from simply selecting plants with desirable characteristics for propagation, to more complex molecular techniques. ...

Lentil (Lens culinaris Medik.) is an important pulse crop with annual production of 3-4 Mt across 70 countries (Cubero et al. 2009. DOI 10.1079/9781845934873.0000; pg. 13). Lentils are a good source of protein, carbohydrates, micronutrients and vitamins for human nutrition and is consumed in more than 120 countries. Furthermore, their small seed size and flat shape make them relatively quick cooking and easily decorticated compared to most other grain legumes (Sharpe et al. 2013. BMC Genomics. DOI 10.1186/1471-2164-14-192). The Lentil plant has a bushy growth habit with a height of about 40 cm; the seeds are lens-shaped and usually grow two per pod. ... [more]

 

Germplasm denoted as Lens interspecific should be a direct cross between two different Lens species.

 

Lens orientalis is a wild relative of Lens culinaris with lanceolate stipules. The geographical distribution of Lens orientalis ranges from Turkey to Uzbekistan with a primary habitat of stony and gravelly niches where aggressive annuals are not successful1. Lens orientalis usually forms small disjunct populations containing a small number of plants in sparse stands1. More extensive populations of L. orientalis were found at high elevations (800 to 2,000 m)1. Recent sequence analysis indicates that Lens orientalis is in the primary gene pool of L. culinaris2 ...
