Description
Summary:"Caja-umbu" (Spondias mombin x Spondias tuberosa) is a native tropical Brazilian fruit tree with a great agro industrial potential. However the existing in situ and ex situ germplasm of this species is extremely restricted and vulnerable. This work aimed to collect, maintain characterize and evaluate 36 accesses of "Caja-umbu" Germplasm Collection owned by Empresa Pernambucana de Pesquisa Agropecuaria (IPA) located in the Northern Coastal Rain Forest region of the State of Pernambuco, Brazil. Plant growth, yield and fruit quality descriptors were evaluated, and data have shown variations on plant height, canopy and stem diameters, production and fruit weight. "Caja-umbu" had shown good adaptation to both climate and soil conditions of Northern Coastal Rain Forest region, in Pernambuco, with some genotypes such, as IPA-8.3, IPA-6.2, IPA-8.2, IPA-1.3 and IPA-5.3 showing outstanding yield characteristics.
