“…The fruit shape and the pericarp thickness are important traits for the classification of accessions, varieties and cultivars of peppers. The positive correlation between these characteristics can directly affect the flavoring compounds essential to the Capsicum fruits [59].…”

Loss of biodiversity and ecosystem degradation become major concerns worldwide, making the conservation process an important strategy for maintaining biodiversity. Capsicum chinense Jacq. is the most Brazilian species of the genus, with representatives in different biomes. Anthropic pressure, such as burns, real estate speculation, and changing cultivation habit has led to risks of genetic erosion. Conservation and characterization of conserved accessions are paramount to ensure genetic diversity, useful for the bioeconomy and for genetic improvement. We report the characterization of 55 C. chinense accessions from four different regions of Brazil and one accession from Peru. The accessions were characterized based on 37 morpho-agronomic variables, Inter Simple Sequence Repeats—ISSR and Simple Sequence Repeat—SSR. Qualitative descriptors were analyzed using a descriptive statistical, while the quantitative descriptors were analyzed via F test and significant differences in mean values were separated using Scott-Knott test. The relative contribution of each quantitative trait was determined. A correlation between morphological and molecular distances was calculated. Color of ripe fruit and fruit shape had the largest number of observed classes. Six distinct groups and the joint analysis presented an entanglement rate of 0.58, evidencing the divergence of accessions between the groups of both dendrograms. Bayesian analysis allowed the distinction of two clusters for SSR. A significant variability was observed among accession with potential to integrate several breeding programs.

“…Disease severity index varied from 0% ('Adelina', 'Red Habanero', 'Red Chupetinho') to 75.0% ('Lemon Drop'). The coefficient of variance (CV) is the ratio of the standard deviation to the mean of a variable (Pena-Yam et al 2019). The coefficient of variation from the test results shows a low value of less than 20% (Gomez and Gomez 1987) on all variables except for the disease severity index (25.51%), which indicates that the test results are valid.…”

Abstract. Sayekti TWDA, Syukur M, Hidayat SH, Maharijaya A. 2021. Morphological response and genetic variability of four species of chili pepper (Capsicum spp.) under infection of pepper yellow leaf curl virus. Biodiversitas 22: 4758-4765. Chili pepper has various types and species, but only five known species are commonly used and consumed. Most cultivated chili is susceptible to various plant diseases, one of which is Pepper yellow leaf curl disease (PYLCD) caused by Pepper yellow leaf curl virus (PYLCV) (Begomovirus, Geminiviridae). To control PYLCD, resistant variety assembly is required to prevent virus infection in cultivated plants. From this research, testing on four chili species is expected to provide information regarding the resistance and performance of chili peppers to conditions infected with PYLCV. This study was conducted at Dramaga Bogor, West Java, Indonesia in two experimental units: planting under virus-free conditions (as control) and virus-infected conditions. Each experimental unit was carried out using a single factor Randomized Complete Block Design (RCBD) with three replications. Twenty-nine genotypes of chili pepper were used consisted of four species, including C. annuum, C. frutescens, C. chinense, and C. baccatum. Of the 29 genotypes tested, thirteen genotypes in the resistant, nine genotypes in moderate resistant, two genotypes in moderate susceptible, three genotypes in the Susceptible, and two genotypes in the highly susceptible category. The heritability, genotypic coefficient of variance (GCOV) and phenotypic coefficient of variance (PCOV) value obtained from testing for all characters is high, ranging from 65.16-99.12%, 14.87-82.60%, and 15.77-84.45%, respectively. Most of the genotypes from C. chinense showed good resistance to PYLCV. In general, by considering the category of the resistance level and other characters such as productivity, ‘Jolokia’ (C. chinense), ‘Anies’ (C. annuum) and ‘Bonita’ (C. frutescens) can be ascertained as potential candidate sources of resistance to PYLCV.

“…'Mayan Kisin' was the result of four selection cycles carried out on landraces collected in the region of Valladolid, in the state of Yucatan, Mexico. A study by Peña-Yam et al [13] estimated the genetic parameters of seven agronomic characteristics for 11 habanero pepper genotypes. The aim of the study was to select potential progenitors to produce F1 hybrids.…”

This study evaluated 29 F1 lines and the 11 genotypes of habanero peppers used in the crossbreeding program developed by the Scientific Research Center of Yucatan, México. A randomized complete block design with four repetitions was used. Eight plants of each of the genotypes were studied per block. A total of 22 qualitative and 18 quantitative descriptors established in the manuals of the International Plant Genetic Resources Institute (IPGRI) and the National Service for Seed Inspection and Certification (SNICS) was used. The multiple correspondence analysis of the qualitative traits explained 38.2% of the total variability. The trait that contributed the most to the qualitative variability identified was the presence of anthocyanins in the node. Principal component analysis showed that the first two axes explained 85.1% of the total variability and that capsaicin content and fruit pericarp thickness were the major contributors to the variation recorded. Based on these results, four F1 hybrids of habanero pepper were selected because of their promising traits for the different markets, i.e., high productive potential and/or high pungency. These traits are described in the section on Results.
