Morphological evaluation of an in situ collection of species from the Annonaceae family in Colombia

Abstract

An in situ collection composed of 167 accessions of the species Annona cherimola, A. glabra, A. reticulata, and A. squamosa, Rollinia sp., and the interspecific hybrid A. squamosa x A. cherimola was established through bioprospecting of genetics resources of the Annonaceae family in the Colombian Andean and Caribbean regions. These accessions were distributed in 13 departments and 48 municipalities. The most representative species of this collection are A. squamosa and A. reticulata, which are derived from traditional cultivars of populated centers with a variable altitude range of up to 1,021 m a.s.l. The morpho-agronomic evaluation was carried out on 98 accessions using 25 qualitative and quantitative descriptors, which identified the phenotypic traits in A. squamosa and A. reticulata that are related to fruit quality, such as size, weight, symmetry, degrees Brix, pH, acidity, seed weight and seed number, which are the more discriminating descriptors, differentiating six clusters in A. squamosa and four clusters in A. reticulata.

Leaf morphological traits of Orophea spp. (Annonaceae): Living collections of Purwodadi Botanic Gardens, East Java, Indonesia

“…In that study, the characters of length to width ratio and base shape were the two most important characters to cluster the group. In another different case, the leaf length and apex shape could discriminate the species of Annona reticulata in Colombia (Castaneda-Garzon et al 2016). However, general descriptions of leaf morphology especially for venation patterns and anatomy of annonaceous leaf type were still considered poorly described (van Setten and Koek-Noorman 1992).…”

Variability of morphological descriptors in Sicilian oat (Avena sativa L.) populations

“…Hence, several papers were devoted to the evaluation, characterization, and conservation of genetic material in many species where the presence of landraces is outstanding. Research explored plant variability at family level such as in the Annonaceae family (Castañeda‐Garzón et al., 2016), at genus level ( Capsicum spp., Junior e Silva et al., 2013), and at species level such as in quinoa ( Chenopodium quinoa Willd. ; Rojas, 2003), cassava ( Manihot esculenta Crantz; de Oliveira et al., 2014; Silva et al., 2017), cocoa ( Theobroma cacao L.; Adewale et al., 2013), rosemary ( Salvia rosmarinus Spenn.…”
