Abstract

The objective of this work was to characterize 119 accessions of guava and 40 accessions of “araçá” sampled in 35 Brazilian ecoregions, according to the International Union for the Protection of New Varieties of Plants (UPOV) descriptors. The majority of “araçá” accessions presented wide spacing of leaf veins, while guava accessions presented medium to close spacing. Most fruits of “araçá” accessions were classified as small, contrasting with medium to large fruits of guava accessions. Most of “araçá” accessions (91%) presented white flesh fruit color, while 58% of guava accessions presented pale pink, pink and dark pink colors. Fruit
differences among wild and cultivated Psidium species indicate fruit as the most altered trait under artificial selection.
