“…The fruit weight, in addition to being a quality determinant, is an important characteristic for the yield determination in pepper plants. It is important to highlight that the average fruit weight can be altered according to the fruit yield per plant (Rêgo et al, 2009b).…”

ABSTRACT. The objective of this study was to determine the effects of the general and specific combining abilities (GCA and SCA, respectively) of 15 characteristics and to evaluate the most promising crosses and the reciprocal effect between the hybrids of six parents of the Capsicum annuum species. Six parents, belonging to the Horticultural Germplasm Bank of Centro de Ciências Agrárias of Universidade Federal da Paraíba, were crossed in complete diallel manner. The 30 hybrids generated and the parents were then analyzed in a completely randomized design with three replicates. The data were submitted to analysis of variance at 1% probability, and the means were grouped by the Scott-Knott test at 1% probability. The diallel analysis was performed according to the Griffing method, model I and fixed model. Both additive and non-additive effects influenced the hybrids' performance, as indicated by the GCA/SCA ratio. The nonadditive effects, epistasis and/or dominance, played a more important role than the additive effects in pedicel length, pericarp thickness, fresh matter, dry matter content, seed yield per fruit, fruit yield per plant, days to fructification, and total soluble solids. The GCA effects were more important than the SCA effects in the fruit weight, fruit length and diameter, placenta length, yield, vitamin C, and titratable acidity characteristics. The results found here clearly show that ornamental pepper varieties can be developed through hybridization in breeding programs with C. annuum.

“…The preference isfor small size and compact plants and with colored and erect fruits. In addition the resistant genotypes to diseases and plagues are desired (Neitzke et al, 2016;Rêgo et al, 2009a;Rêgo et al, 2012a). The easy propagation through seeds, the relatively short time for cultivation, and the tolerance to heat and drought also contribute to its utilization as ornamental plant (Rêgo et al, 2012a).…”

The genus Capsicum comprises a wide variety of peppers and peppers, with different sizes, colors and flavors. The present work had the objective to characterize and evaluate the genetic divergence among eight accessions of pepper (Capsicum annuum). The experiment was developed at the Federal University of Paraíba, Areia - PB. Eight accessions of pepper belonging to the germplasm bank of the CCA-UFPB were used. The experimental design was completely randomized. Data were submitted to analysis of variance by the F test at a level of 5% and 1% significance and the means were grouped by the Scott Knott test at 5% and 1% significance. For the analysis of genetic divergence, the Tocher grouping method and canonical variables were used. The treatment effects were significant, by the F test, at a level of 1% for all the characteristics evaluated, except for crown width and stem diameter, which were significant at 5% probability. According to the results obtained in the Scott & Knott test at 5% and 1% probability, the accessions were differentiated into two to six different classes. According to Tocher’s methodology the accessions were grouped into two groups. In the analysis of the canonical variables, the first three variables explained 94.18% of the total variance, and four different groups were formed according to the graphical dispersion.

“…são fontes importantes de três antioxidantes naturais: vitamina C, carotenoides e vitamina E (Rêgo et al, 2010;Rêgo et al, 2011a;Rêgo et al 2011b;Rêgo et al, 2012a). Nota-se também que, pela grande diversidade observada para diversas características, como porte, folhagem e coloração dos frutos, tem ocorrido a inserção das pimentas no mercado de plantas ornamentais (Rêgo et al, 2009;Finger et al, 2012).…”

O objetivo deste trabalho foi caracterizar progênies de uma população base de pimenteiras (Capsicum annuum L.). Foram utilizadas 54 plantas de uma geração F2 de pimenteiras ornamentais, para se avaliarem os seguintes caracteres morfoagronômicos: altura da planta (AP), diâmetro da copa (DDC), altura da primeira bifurcação (APB), diâmetro do caule (DCL), comprimento da folha (CFL), largura da folha (LFL), comprimento da corola (CDC), comprimento de antera (CANT), comprimento do estilete (CES) e largura da pétala (LAP). O delineamento experimental foi inteiramente casualizado, com três repetições. Os dados foram submetidos à Análise de Variância, com posterior agrupamento das médias para o teste de Scott-Knott (p<0,01). Com exceção do CANT, verificaram-se diferenças significativas para os demais descritores, pelo Teste F. O DCL foi o descritor com maior herdabilidade (99,49%), seguido de DDC (96,14%) e APB (94,05%). O caractere DCL apresentou maior variabilidade entre as plantas, formando 13 classes, seguido de DDC, com oito e APB, com seis classes. Quando se utilizaram as técnicas multivariadas, foi possível agrupar as 54 plantas em oito grupos, sendo o grupo 1 o que reuniu maior número de plantas (35). A característica que mais contribuiu para a divergência genética foi o diâmetro do caule (68,97%), seguida pelo diâmetro da copa (9,22%), altura da primeira bifurcação (6,76%) e altura da planta (4,58%). Já as características de flor foram as que menos contribuíram para a variabilidade (10,47%). Houve variabilidade entre as plantas estudadas, sendo possível praticar seleção dentro dessa família, dando continuidade ao Programa de Melhoramento de Pimenteiras.
