“…Cross-pollination rate among Capsicum spp. is highly variable, ranging from 2 to 90% [12]. The species C. annuum, C. chinense and C. frutescens, form a morphological complex of overlapping characters from a common base of genes; qualitative characters, such as floral characteristics, differentiate the three species morphologically.…”

In order to assess the potential of 192 accessions of Capsicum L., from 21 countries, a morphological and agronomic characterization was carried out by applying 57 qualitative and quantitative descriptors. Multivariate analyses identified two large groups: the first including C. annuum (G3, G5, G7 and G8) and the second C. frutescens, C. baccatum, C. chinense and C. pubescens (G1, G2, G4, G6 and G9). The discriminant qualitative descriptors were the colour of the corolla, the colour of the anthers and position of the flower. The quantitative discriminant characteristics were length, weight and width of the fruit. The participatory selection identified 15 materials by colour, aroma, texture, flavour, size and thickness of fruits. Chemical analyses determined the highest concentration of flavonoids in the accessions 10,757 (16.64 mg/g) and 15,661 (15.77 mg/g). Accessions 17,750 (11.68 mg/g) and 10,757 (11.41 mg/g) presented the highest polyphenol contents. The highest capsaicin concentration was recorded in accessions 16,209 (55.90 mg/g) and 10,757 (48.80 mg/g). The highest antioxidant value was recorded in accessions 17,750 (90.85 mg/g) and 15,661 (87.03 mg/g). All these characteristics are important with a view to increasing industrial use and genetic improvement processes. These results show the existence of significant genetic variability within the genus Capsicum.

“…Its native region is America, particularly Mexico, and it is found in hot and humid climates (Thang, 2007). The predominant fertilization method in capsicum plants is cross-fertilization, which varies greatly and ranges from 2 to 90% (Justino et al, 2018). The flowers in the Capsicum annum species are single and white in color (Melgarejo, 2004.…”

For protect biodiversity and preserve local genetic types, the research was carried out to evaluate some morphological traits of several locally types from Capsicum annuum Plant (Qarn-Aljamous, Qarn-Alghazal, Haskuria, Long-Mutabasha, Short-Mutabasha, Safrania, and Harimia) of Idlib Governorate in northwestern Syria for the agricultural season 2022. The morphological characterization was carried out by applying 20 qualitative characterizations that included the characteristics of plants, flowers, fruits and seeds. The distinctive qualitative morphological characteristics were the nature of the flower growth, the shape of the fruit, the appearance or absence of the base of the fruit, and the wavy cross-section of the fruit. Morphological characterization results of the studied types, based on some morphological characteristics, showed that there is a difference between these types, especially in the character of the nature of flower growth and fruit traits. The results of the cluster analysis also showed that the studied models were distributed into two groups: the first included (Long-Mutabasha, Short-Mutabasha, Safrania, and Qarn-Aljamous) and the second included (Qarn-Alghazal, Haskuria, and Harmia

“…Our assumption is supported by the fact that the out crossing rate in Capsicum varies greatlyfrom 2 to 90% (Tanksley, 1984;Pickersgill, 1997) and the interspecific crosses compatibility between accessions of C. chinense with C. annuum ranged between 8.9% and 40.0% (Costa et al 2009), within the genius C. annuum, the rate of natural cross-pollination was estimated to be 1.2% overall. (Justino et al, 2018).…”

Exploring agro-morphological diversity of Algerian hot pepper (Capsicum annuum L.) accessions using multivariate statistics

Pepper is an inevitable constituent in the diets of Algerian population. Unfortunately, the local landraces are endangered by both genetic erosion and pollution. This study aimed to perform agro-morphological characterization of hot peppers (Capsicum annuum L.) accessions. Twenty one accessions collected from the east and south of Algeria were evaluated for 24 quantitative and 38 qualitative morphological characters under green-house conditions. The trial was conducted in a Randomized Complete Block Design (RCBD), with four replicates at the experimental station of the Department of agronomical sciences of Biskra University in Southeast Algeria. Signiﬁcant variations in most of the traits were strikingly demonstrated using variance analysis and coefficients of variation and the number of modalities, frequencies and Shannon–Weaver diversity index (H′) values for the quantitative and qualitative characters respectively indicating the heterogeneity of the studied accessions. The correlations between the studied quantitative variables showed that the yield parameters were correlated with the variables related to the vegetative part of the plant. The first five PCs explained 76.877 % of the total variation and identified the most discriminant variables related particularly to yield and fruit characteristics contributing to PC1: fruit width; fruit index; fruit weight, number of locules; placenta length, pedicel length, anther length, leaf width and plant height /stem length ratio. For several qualitative traits, an important degree of variability was observed. The ﬁrst factorial dimension explained 42.5% of the variance and was mostly associated with: plant height; growth habit; flower position; corolla shape; number of flower per axil and fruit shape at pedicel attachment and at blossom end; calyx margin. Cluster analysis of the combined data grouped the pepper landraces into four clusters regardless of the localities and the closest accessions belonged to different localities and/or provinces. This study notably confirms the presence of considerable genetic diversity within and between accessions of hot pepper in Algeria and provides a basis for its active conservation and future selection to develop improved local pepper populations
