Transition from targeted breeding to mainstreaming of biofortification traits in crop improvement programs por Virk, Parminder S., Andersson, Meike S., Arcos, Jairo, Govindaraj, Mahalingam, Pfeiffer, Wolfgang H.

“…It is envisaged that the mainstreaming of biofortification traits will be driven by high-throughput micronutrient phenotyping, genomic selection coupled with speed breeding for accelerating genetic gains. It is noteworthy that targeted breeding gradually leads to mainstreaming, as the latter capitalizes on the progress made in the former. …”
