N2 - Conservation of plant genetic resources (PGR) is essential to preserve diversity and to provide genes for plant breeding. This paper assesses the current status of pineapple PGR diversity in Cuba and actions are proposed to minimize the loss of diversity. In situ diversity was evaluated through field trips to different locations across the country, evidence was found that pineapple germplasm diversity is low. Only three (Spanish, Cayenne and Pernambuco) out of the five horticultural groups of this crop are presently planted at Cuba. Red Spanish is the predominant cultivar, and White Pineapple is an endangered one. The highest diversity was found at the Eastern region, where it was possible to find at least two different cultivars from each of these three groups. The ex situ pineapple collection contains 56 accessions, 45 % belong to the Spanish group, 20 % to Cayenne and 14 % to Pernambuco, while the rest are hybrids, improved cultivars and other related species. Threats of diversity loss were identified by the Research-Action-Participation method. Farmers and experts agreed that growing of the most common cultivars is being abandoned and consequently, there is high risk of loss of in situ diversity. Results document the low diversity of pineapple genetic resources in the country and the need to use in situ and ex situ conservation approaches as complementary strategies for germplasm preservation for future generations.
