Article Synopsis
- Cowpea is vital for family farming in Senegal, contributing to the economy and food security, yet little is known about local variety classification and associated social practices.
- Surveys with 335 rural farmers across 37 villages revealed a high diversity of cowpea varieties, with 59 local names, mostly related to seed morphology or color.
- More than half of farmers (57%) obtain their cowpea seeds from outside their village, indicating a need for incorporating local expertise and diversity into breeding programs.
Background: Pearl millet, a nutritious food for around 100 million people in Africa and India, displays extensive genetic diversity and a high degree of admixture with wild relatives. Two major morphotypes can be distinguished in Senegal: early-flowering Souna and late-flowering Sanio. Phenotypic variabilities related to flowering time play an important role in the adaptation of pearl millet to climate variability.

- Pearl millet is a critical food source for over 90 million farmers in dry regions of sub-Saharan Africa, India, and South Asia.
- Researchers have sequenced the whole genome of a reference genotype, revealing approximately 38,579 genes and a focus on genes related to wax biosynthesis, which may enhance the crop's heat and drought resistance.
- The study also involved resequencing 994 pearl millet lines to explore genetic diversity and domestication, aiming to support genomic selection and hybrid performance prediction for better breeding outcomes.
Background: Pearl millet is a staple food for people in arid and semi-arid regions of Africa and South Asia due to its high drought tolerance and nutritional qualities. A better understanding of the genomic diversity and population structure of pearl millet germplasm is needed to support germplasm conservation and genetic improvement of this crop. Here we characterized two pearl millet diversity panels, (i) a set of global accessions from Africa, Asia, and the America, and (ii) a collection of landraces from multiple agro-ecological zones in Senegal.
