What makes a wild lentil wild?

Overview
2018

    Growth habit, seed size and shattering are some of the most significant agronomic traits involved in the domestication process. Wild lentils tend to be prostrate while cultivated ones need to be upright, especially for disease avoidance and mechanical harvesting. Wild lentil seeds are tiny while cultivated ones tend to be slightly to significantly larger, depending on market class.  Shattering is an effective method of seed dispersal in the wild but leads to terrible yields under crop conditions!

    We are phenotyping and genotyping several interspecific RIL populations with a view to tagging regions of the lentil genome associated with the shift from a wild phenotype to a more farmer-friendly one. For phenotyping purposes, we are developing an imaging system (Nielsen, K et al, manuscript in preparation) to characterize more accurately and automatically traits such as leaf surface area and biomass.

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. ...
