  author={Brigitte L Maass and Oliver Robotham and Mark A. Chapman},
  journal={Genetic Resources and Crop Evolution},
Studying molecular genetic relationships can substantially contribute to the understanding of the pathways of domestication of a species. Although an increasing number of molecular genetic studies have been performed on Lablab purpureus (hyacinth bean), many covered germplasm of restricted geographic origin or limited intra-specific systematic position. Integrating the molecular diversity found with phenotypic or morpho-agronomic diversity is also deficient. This investigation combines findings…

Population genetic analysis of hyacinth bean (Lablab purpureus (L.) Sweet, Leguminosae) indicates an East African origin and variation in drought tolerance
An East African origin of Lablab is proposed and potential adaptive diversity for future crop breeding attempts is identified, with variation in tolerance to drought recorded, with some lines able to tolerate 14 days without watering.
Determining Sources of Diversity in Cultivated and Wild Lablab purpureus Related to Provenance of Germplasm by using Amplified Fragment Length Polymorphism
The molecular analysis identified forms that were collected in the wild in India but were genetically placed intermediate between wild and cultivated forms and support the suggested pathway of domestication and distribution of L. purpureus from Africa to Asia.
