“…The later accession, commonly known as "pimenta-de-cheiro" (C. chinense), showed the higher average, with176 cm. Similar results were obtained by Araújo et al (2018) that analyzed 20 genotypes of peppers belonging to Peruvian, Colombian, and Brazilian Amazon Forest, and observed C. chinense with a greater high of 100.12 cm. The accessions BAGC 110, 177, and 209 were clustered for NDF and NDM, presenting later reproductive cycle and later days to fruiting (Table 3).…”

This research aimed to morphologically characterize and estimate the genetic diversity of 21 Capsicum accessions belonging to the Capsicum Germplasm Active Bank at the Universidade Federal do Piauí (BAGC-UFPI) using uni- and multivariate analysis. The experiment was carried out in a greenhouse, by completely randomized experimental design with four repetitions, with one plant per plot. Analysis of variance (ANOVA) and the comparison of means for seven quantitative variables were performed, followed by clustering the averages by the Scott-Knott test (P < 0.05). The analysis of the seven quantitative and thirteen qualitative descriptors was estimated based on the Gower distance. Later, it was performed the principal component analysis and the UPGMA hierarchical cluster method. Results characterized and identified a wide intra- and interspecific genetic variability related to the fruit size, colors, and shapes among the Brazilian Capsicum genotypes belonging to the BAGC-UFPI. The descriptors used in this research were effective in the discrimination of the pepper accessions, especially the closely related C. frutescens and C. chinense species.

“…Nitrogen fertilization positively affected plant growth without altering antioxidant content. Regarding the growth of pepper genotypes, in general, the results of the present study are similar to those reported by Araújo et al (2018) and Ferraz et al (2016). In pepper plants, plant height and stem diameter are strongly influenced by nitrogen fertilization (Oliveira et al, 2013).…”

“…In C. chinense, fruit yield is similar, ranging from 280-570 g per plant (Domenico et al, 2012). In traditional varieties of C. chinense, fruit yield was, on average, 380 g. However, these varieties presented great variation for fruit yield, ranging between 70-1920 g per plant (Araújo et al, 2018), indicating large amplitude for this characteristic.…”

The present study evaluates the fruit yield and antioxidant activity of pepper genotypes as a function of nitrogen doses. The experiment was conducted in a greenhouse with seven pepper genotypes: two C. annuum (116 and 163), two C. chinense (39 and 118), two C. frutescens (17 and 113), and one C. praetermissum (141), and 11 nitrogen doses (0, 1, 2, 4, 8, 16, 32, 64, 128, 256 and 512 N mg dm-3). Productive parameters were evaluated, and antioxidant compounds were determined by spectrophotometric methods. Genotypes 116 and 163 showed a higher fruit fresh mass, and genotype 141 produced the highest number of fruits per plant. Genotypes 141 and 163 were the earliest. The highest antioxidant activity was obtained in the extracts of fruits of genotype 113. Nitrogen fertilization did not affect the antioxidant content of fruits. The pepper genotypes of the present study have comparable bioactive compound contents and antioxidant activity. Therefore, they are promising genotypes for the vegetable production sector, with potential for industrial and pharmacological use.

“…Such complex studies lead to precise recommendations through the programming of hybridization to create variability (Tirupathamma et al, 2018). Characterization of the value of a genotype must be done by means of some descriptors, among which the most used are the number of fruits per plant and their weight (Araujo et al, 2018).…”

The purpose of the study was to evaluate the variability of a collection of paprika peppers landraces, in order to use them in the breeding process. The study lasted two years. The biological material was collected from western Romania. The behavior of landraces is not constant from year to year. Zărand landrace was the most stable. They can be recommended as genitors the landraces: Craiva for fruit length (15.11 cm), Cermei for fruit diameter (3.06 cm) and fruit weight (38.30 g), Apateu II for the number of fruits per plant (22.26 fruits), Apateu II for fruits weight per plan (491.41 g). In respect of the drying efficiency was noted the Buzad landrace (over 20%). Considering the production of the plant and the efficiency in processing, for maintaining in the culture it is recommended the Apateu II landrace which has the highest fruit production per plant, the fruits being smaller. The variability within populations allows the selection to be applied, being medium or small for the size of the fruits and large for the weight of the fruit and the weight of the fruits on the plant. The studied collection is useful for breeding programs, but must be performed molecular analyzes.
