The hot peppers belonging to the species C. baccatum are completely restricted to Latin America and comprise the most popular hot pepper consumed as fresh or as processed paprika in Andean countries. The objective of this study was to characterize the phenotypic diversity among 40 landrace accessions of C. baccatum based on morphological fruit quality traits and yield components, and to determine the correlation between these characters and their contribution for the genetic variability.

Morphological and chemical characterization of fruits of Capsicum spp. accessions
The data showed high genetic variability to future use in a Capsicum breeding program, and the accessions 33, 44 and 41 showed major values for dry matter content and total soluble solids; these should be used to improve these traits in a paprika breeding program.
Characterization and genetic diversity of pepper (Capsicum spp) parents and interspecific hybrids.
The principal component analysis results corroborated the morphological and random-amplified polymorphic DNA data, and three groups that contained the same individuals were identified, which confirmed reports in the literature regarding the phylogenetic relationships of the species used as parents.
Classification of Local Pepper Collections (Capsicum spp.) from Eritrea Using Morphological Traits
The results of the current study revealed the relatively high level diversity existed within the evaluated collections and partitioned them into meaningful groups.
Variation of plant and fruit traits in native Mexican costeño pepper
ABSTRACT In a collection of costeño peppers conserved by indigenous producers from the municipalities of Santa Maria Tonameca and Santo Domingo de Morelos, Oaxaca, Mexico, a description and
Phenotypic characterisation of the germplasm bank of mangaba (Hancornia speciosa Gomes), a unique Brazilian native fruit, with emphasis on its high vitamin C content
Findings on the vitamin C content and FM of these accessions of mangaba will be useful for the agro-economic development of this native Brazilian species.
Genetic diversity among accessions of Capsicum annuum L. through morphoagronomic characters
There is phenotypic divergence between the accessions of Capsicum annuum L. which can be used in ornamental peppers’ breeding programs, indicating the selection of promising individuals for ornamental purposes.
Evaluation of production and quality traits in interspecific hybrids of ornamental pepper
The studied parents and hybrids diverged for the evaluated traits; however, there was difficulty in obtaining good interspecific hybrids with traits of importance, wherein combinations HS1×L7, L2×L6, and HS1–L2 met these requirements.
Phenotyping and selecting parents for ornamental purposes in pepper accessions
The market for ornamental peppers in Brazil is arising and breeding new cultivars adapted to Brazilian environmental conditions is necessary. This work describes the characterization of 22 pepper
Molecular and agronomic analysis of intraspecific variability in Capsicum baccatum var. pendulum accessions.
Wide variability among the accessions comparing phenotypic and genotypic data and revealed distinct patterns of dissimilarity between matrices are revealed, indicating that both steps are valuable for the characterization of C. baccatum var.


A diallel study of yield components and fruit quality in chilli pepper (Capsicum baccatum)
Analysis of variance for the combining ability of peppers showed that GCA effects exhibited significant difference and SCA effects of the crosses were significant, except for the height of first bifurcation.
Diallel analyses and estimation of genetic parameters of hot pepper (Capsicum chinense Jacq.)
Dominant gene action, ranging from incomplete dominance to probable overdominance, was responsible for heterosis in those traits where no epistatic genetic action was detected, and non-additive genetic effects were larger than additive effects for all the traits assessed.
Relationship between heterosis and genetic distance based on morphological traits and AFLP markers in pepper
The correlations of morphological distances with mid-parent heterosis were significant for days to flowering and maturity, suggesting earliness can be predicted from Morphological distances of parental lines, but the correlations of AFLP-measured genetic distances were non-significant for all characters, except for fruit diameter, and proved to be of no predictive value.
Nuclear RFLP between pepper cultivars (Capsicum annuum L.)
A correspondence analysis performed on differences between the global RFLP patterns of each accessions of C. annuum revealed the particular genomic structure of four small fruited cultivars: Criollo de Morelos 334, H3, Perennial and Doux Long des Landes, indicating that molecular markers will be more usable in intraspecific study of C.'s annuum than isozyme markers.
Genetic diversity analysis of peppers: a comparison of discarding variable methods
The data showed that the two compared methods differed, since Singh’s and principal component methods showed different variables to be discarded, and the Singh method was not efficient in detecting multicollinearity among variables.
Variation for bioactive compounds in ají (Capsicum baccatum L.) and rocoto (C. pubescens R. & P.) and implications for breeding
The results show that in both growing conditions C. baccatum presents a considerable variation for most of the traits studied, with several accessions having similar or higher levels than C. annuum for the compounds studied, which indicates that C.baccatum is an important source of antioxidant compounds with nutritional value.
Genetic variability, heritability and genetic advance in hot chilli ( Capsicum chinense Jacq.)
High estimates of heritability coupled with high genetic advance were also observed for these characters, indicating that they can be effectively improved through selection.
Restriction fragment length polymorphism and genetic distance among Mexican accessions of Capsicum
Restriction fragment length polymorphism analysis was performed on 25 accessions of pepper (Capsicum sp.) from various regions of Mexico and on the two parents currently in use for molecular mapping.
Variability, heritability and genetic advance in chilli ( Capsicum annuum L.)
High heritability coupled with high genetic advance observed for these characters imply the potential for crop improvement through selection.
