“…Generally, differences in pitahaya germplasm can be easily shown with some distinguishing phenotypic characteristics, such as fruit size, fruit color, and number of spines at the areola that formed on branch/stem segments [6]. Nowadays, it is very difficult to separate species and varieties of the dragon fruit because of high intra and interspecific hybridization that has created some taxonomical confusion worldwide [7]. Morphological and genetic heterogeneity in many fruit characteristics, such as sweetness, size, shape, color, and bracts number, resulting from intra and inter-specific hybridization that makes it difficult to increase quality standards for the exportation market, posing serious problems when determining performance in handling and shelf-life [8].…”

Yellow pitahaya is an exotic fruit that is rich in essential nutrients and antioxidants. In Colombia, it grows naturally in warm areas, but it is not clear which species exist because this genus presents a lot of intra and interspecific hybridization. More studies are needed in this field along with characterizations of the genotypes. This study aimed to undertake an in situ morphoagronomic evaluation of yellow pitahaya genotypes from five municipalities in Boyacá, Colombia. Measurements were taken in a completely random design. Qualitative and quantitative descriptors for cladodes, fruits and covered production systems were evaluated with a descriptive analysis, Spearman correlation variance, and multivariate and cluster analysis. The results showed that cladode characteristics such as cladode width, distance between areoles, number of spines, length of areoles, margin ribs of cladode and waxiness could be used to identify Megalanthus spp. Characteristics such as weight (270–274 g), size (100 mm), color of the fruit and pulp as well as acidity (0.18) and soluble solids (15.7) were highly variable between the genotypes. Genotypes with good morphological and fruit characteristics were identified (Gen2 and Gen9), which can provide the bases for the selection of pitahaya that satisfy the needs of farmers and consumers.

“…The UPGMA method has been widely used for the analysis of morphological traits in plant breeding (Carović-Stanko et al, 2011;Dossou-Aminon et al, 2014;Silva et al, 2017). Cluster analysis performed by the UPGMA method distinguished five homogeneous groups.…”

Variation in productivity traits and their correlations were studied in 16 hybrid lines of Aegilops kotschyi Boiss. and A. variabilis Eig. with Triticum aestivum L. and their parental components. In comparison to the wheat cultivars, most of the hybrid lines exhibited higher tillering, whereas the length of the main tiller and spike rachis were similar to the values for the wheat cultivars. The values of other traits, such as basal stem diameter, main spike density, fertility, and a 1,000-grain weight in hybrid lines were varied. In some lines, the value of these traits was higher or similar to that of wheat cultivars, whereas in others it was lower. Among the hybrids, [(A. kotschyi × ‘Rusałka’) × ‘Begra’] × ‘Turnia’ was distinguished in having the greatest basal stem diameter, longest spikes, highest fertility, and greatest 1,000-grain weight. The hybrid lines exhibited greater variation in the analyzed traits than did the wheat cultivars. In the hybrid lines, the main tiller length and basal stem diameter were positively correlated with fertility and 1,000-grain weight, whereas in wheat cultivars there were negative correlations for these traits. The results confirmed that wide hybrids can be used to eliminate the negative correlations between productivity traits in wheat. Analysis of clusters in terms of productivity traits provided information on the similarity and diversity of hybrid lines, which may prove useful in their further selection.

“…Along with the advancement of agriculture in Brazil, the exotic fruits market has also been boosted and has been increasing recently (WATANABE;OLIVEIRA, 2014;PITAYA DO BRASIL, 2021;HFBRASIL, 2021). Thus, pitaya, popularly known as Dragon fruit, has drawn much attention from consumers because of its sensory characteristics, nutritional and exotic aspects (Silva et al, 2017). However, the interest of fruit growers is the high commercial value of pitaya fruits, therefore, considered a promising alternative for developing Brazilian fruit production (CORDEIRO et al, 2015;SILVA et al, 2018;PITAYA DO BRASIL, 2021).…”

This study aimed to evaluate the effect of organic and inorganic fertilizers on the pitaya’s Hylocereus undatusperformance under field conditions. The experimental design used was Completely Randomized Block Design (CRBD). Five treatments consisting of the four different fertilizer dosages were included in this study, namely T1 (00-120-320-120); T2 (04-080-160-080); T3 (06-060-100-060); T4 (08-000-000-000) and T5 (Control: 00-000-000-000) of bovine manure (kg pit-1), urea (g pit-1), super simple (g pit-1) and potassium chloride (g pit-1), respectively. Parameters such as height, number, length, width, area, and volume of the cladodes were assessed at 20 and 320 days after planting. The number of fruits produced and mineral composition (N, K, Ca, Mg, P, and S) of H. undatusplants were also assessed. The results on morphometric characteristics of the cladodes, macronutrient composition and fruit yield have been recorded with higher values in treatments 3 and 4. However, according to the principal component analysis performed, treatment 3 was the one that correlated with the evaluated characteristics. The results have clearly indicatedthe importance of combination of adequate dose of mineral and organic fertilizer for better vegetative performance and yield of pitaya crop.
