“…It is very aromatic and spicy, with a degree of pungency around a Scoville rating of 50,000 SHU, Scoville heat units, corresponding to level 8 in the heat scale. 'Cumarido-Pará' is widely used as a canned product (IBURG, 2005;LINGUANOTTO NETO, 2004). The variety BRS Seriema, developed from the CNPH 3773 genotype belongs to the varietal group popularly known as "goat".…”

“…The most common are C. annuum L., C. baccatum L., C. chinense Jacq., C. frutescens L., and C. pubescens R. & P., and horticulturists have cultivated these species worldwide for long time (Casali and Couto, 1984;Moscone et al, 2007). In Brazil, the most indigenous is C. chinensis because this species has a large genetic diversity in the upper Amazon, and it is well adapted to the diverse environmental conditions around the country (Lannes et al, 2007).…”

ABSTRACT. We estimated the genetic diversity of 49 accessions of the hot pepper species Capsicum chinensis through analyses of 12 physicochemical traits of the fruit, eight multi-categorical variables, and with 32 RAPD primers. Data from the physicochemical traits were submitted to analysis of variance to estimate the genetic parameters, and their means were clustered by the Scott-Knott test. The matrices from the individual and combined distance were estimated by multivariate analyses before applying Tocher's optimization method. All physicochemical traits were examined for genetic variability by analysis of variance. The responses of these traits showed more contribution from genetic than from environmental factors, except the percentage of dry biomass, content of soluble solids and vitamin C level. Total capsaicin had the greatest genetic divergence. Nine clusters were formed from the quantitative data based on the generalized distance of Mahalanobis, using Tocher's method; four were formed from the multi-categorical data using the Cole-Rodgers coefficient, and eight were formed from the molecular data using the Nei and Li coefficient. The accessions were distributed into 14 groups using Tocher's method, and no significant correlation between pungency and origin was detected. Uni-and multivariate analyses permitted the identification of marked genetic diversity and fruit attributes capable of being improved through breeding programs.

“…According to Lannes et al (2007) and Rêgo et al (2011a), this trait PT is important for the selection of more adequate varieties for the sale of fresh products, because they are resistant to post-harvest damage.…”

ABSTRACT. Pepper species exhibit broad genetic diversity, which enables their use in breeding programs. The objective of this study was to characterize the diversity between the parents of different species and their interspecific hybrids using morphological and molecular markers. The parents of Capsicum annuum (UFPB-01 and -137), C. baccatum (UFPB-72), and C. chinense (UFPB-128) and their interspecific hybrids (01x128, 72x128, and 137x128) were used for morphological and molecular characterization. Fruit length and seed yield per fruit (SYF) traits showed the highest variability, and three groups were formed based on these data. CVg/CVe ratio values (>1.0) were calculated for leaf length (1.67) and SYF (5.34). The trait that most contributed to divergence was the largest fruit diameter (26.42%), and the trait that least contributed was pericarp thickness (0.33%), which was subject to being discarded. The 17 primers produced 58 polymorphic bands that enabled the estimation of genetic diversity between parents and hybrids, and these results confirmed the results of the morphological data analyses. The principal component analysis results also corroborated the morphological and random-amplified polymorphic DNA data, and three groups that contained the same individuals were identified. These results confirmed reports in the literature regarding the phylogenetic relationships of the species used as parents, which demonstrated that C. annuum was closer to C. chinense as compared to C. baccatum.
