Morphoagronomic characteristics display high genetic diversity in murupi chili pepper landraces

Murupi chili pepper is a hot Amazonian pepper that has been used as flavoring in the region, yet its diversity is unknown. This paper aims to assess the diversity in 20 landraces from Peruvian, Colombian, and Brazilian Amazon. The experiment was installed in Manaus-AM, using a randomized complete bl...

description Murupi chili pepper is a hot Amazonian pepper that has been used as flavoring in the region, yet its diversity is unknown.
