Genetic variability in accessions of the acerola germplasm bank of Universidade Federal Rural de Pernambuco, Brazil
Authors: R.M. Moraes Filho1, L.S.S. Martins2, R.S. Musser3, A.V.V. Montarroyos3 and E.F. Silva2
Brazil is the world’s largest producer of acerola, Malpighia emarginata (Malpighiaceae); the Northeast is responsible for 60% of the national production. The culture of acerola in Brazil has great genetic variability; plantings have high phenotypic diversity and are not very productive, often originating from propagation by seed. We evaluated the ge..
