The Potential Of Refugee Seed Systems To Promote Contemporary Adaptation In Traditional Crops: A Case Study Of African Maize In New England, Andi Kur
Graduate College Dissertations and Theses
There are many mechanisms by which landraces evolve in a contemporary agricultural setting; however, the influence of forced human migration on landrace redistribution and evolution has received little attention in comparison to the stochastic effects of drift, mutation, and gene flow in the centers of origin. Although the seed systems of forcedly-displaced people remain poorly understood, evidence suggests that refugees often continue to grow traditional crops after resettlement. From a genetics perspective, the crops that are transported to highly disparate environments provide an interesting opportunity to study adaptation.
This research addresses how forced human migration has impacted contemporary landrace evolution …
