Although strawberry can be cultivated in all types of climate, it grows best in temperate climates, limiting its
cultivation in certain countries or regions with tropical or subtropical climates. The objective of this study was to
verify the genetic diversity of 34 pre-selected day-neutral strawberry genotypes in humid tropical and subtropical
conditions through characterization of morpho-agronomic characteristics and molecular markers. The selection
was based on qualitative and quantitative morpho-agronomic traits, using the Gower algorithm. Molecular
characterization was performed with AFLP markers, using four combinations of selective primers. Six representative variables were subjected to principal component analysis (PCA) and the Mulamba and Mock selection
index. Soluble solids and luminosity of the outer part of the fruit did not differ among genotypes but presented
values above those usually found. AFLP markers detected 80% polymorphism, confirming high genetic variability among genotypes. Clustering based on molecular and agronomic data separated the genotypes into three
groups, and the Mulamba and Mock index did not select individuals derived from ?Albion? or RVFS06. PCA
highlighted the genotypes RVCA16M-1, RVDA11M-3, RVDA11M-4, and RVDA11M-25 as superior for most of the
evaluated traits compared with the commercial cultivars ?Albion? and ?Monterey?. The PCA and selection index
results indicate the reliability of the multivariate analysis for selecting superior strawberry genotypes for
cultivation in tropical regions. Of the 34 genotypes analyzed, four stood out with potential for immediate
cultivation. MenosAlthough strawberry can be cultivated in all types of climate, it grows best in temperate climates, limiting its
