“…We found highly significant differences for all studied traits. Significant differences among chilli pepper genotypes were also reported [23][24][25][26][27]. In the present study, the GCA and SCA variance was significant (p ≤ 0.01) for all studied traits.…”

Chilli pepper is commercially cultivated as a spice and is also used for the extraction of a colouring agent. Here, we performed a diallel genetic study involving five chilli pepper varieties. Parents and their hybrid were evaluated for fifteen morphological and five biochemical traits over two crop seasons under open field conditions. Variation was recorded for all of the studied traits. Similarly, significant values for general combining ability (GCA) and specific combining ability (SCA) variance were obtained for all of the traits. The ratio of σ 2 SCA/σ 2 GCA indicates that non-additive gene effects were predominant for all the studied traits except for fruits plant −1 . Based on SCA effects, cross combinations P2 × P5, and P4 × P5 were determined excellent for flesh thickness, yield components and vitamin C. These hybrids are recommended for multilocation testing to assess their suitability for commercial cultivation. Overall, this work presents useful information regarding the genetics of important morphological and biochemical traits in chilli pepper.

“…These results agree with those by Marame et al (2009), Rêgo et al (2011), and Silva et al (2013), who respectively investigated heritability, phenotypic diversity, and genotypic correlations in Capsicum genotypes. Evaluating F 1 Capsicum annuum genotypes, Butcher et al (2013) found similar values of broad-sense heritability for FW (0.982), FL (0.983), GFD (0.988), and PT (0.911).…”

“…NFP was negatively correlated with FL and PcL, which is an expected result. Butcher et al (2013) found high (>0.8) significant (p<0.05) values of correlation among FW, FL, and FD. Krishnamurthy et al (2013) also obtained negative phenotypic correlations (p<0.01) between NFP and FW, and FL.…”

-The objective of this work was to build weighted correlation networks, in order to discover correlation structures and link patterns among 28 morphoagronomic traits of chili pepper related to seedling, plant, inflorescence, and fruit. Phenotypic and genotypic information of 16 Capsicum genotypes were analyzed. Correlation structures and link patterns can be easily identified in the matrices using the Fruchterman-Reingold algorithm with correlation network information. Both types of correlations showed the same general link pattern among fruit traits, with high broad-sense heritability values and high aptitude of the genotypes for agronomic and ornamental breeding. Leaf dimensions are correlated with a cluster of fruit traits. Correlation networks of chili pepper traits may increase the effectiveness of genotype selection, since both correlated traits and groups can be identified.Index terms: Capsicum, correlation structure, genetic covariance, link pattern, plant breeding. Análise de rede de correlação entre caracteres fenotípicos e genotípicos de pimenteirasResumo -O objetivo deste trabalho foi construir redes ponderadas de correlação, para descobrir estruturas de correlação e padrões de ligação entre 28 caracteres morfoagronômicos de pimenteiras, relacionados à plântula, planta, inflorescência e fruto. Informações fenotípicas e genotípicas de 16 genótipos de Capsicum foram analisadas. Estruturas de correlação e padrões de ligação podem ser facilmente identificados nas matrizes por meio do algoritmo Fruchterman-Reingold, com as informações da rede de correlações. Ambos os tipos de correlação mostraram o mesmo padrão geral de ligação entre caracteres de frutos, com altos valores de herdabilidade no sentido amplo e grande aptidão desses genótipos para o melhoramento agronômico e ornamental. As dimensões das folhas estão correlacionadas ao grupo de caracteres de fruto. Redes de correlação de caracteres de pimenteiras podem aumentar a eficácia da seleção de genótipos, uma vez que tanto caracteres correlacionados quanto grupos podem ser identificados.Termos para indexação: Capsicum, estrutura de correlação, covariância genética, padrão de ligação, melhoramento de plantas.

“…This trend reflects a shift in preference of pepper producers, who are increasingly demanding as to productivity, quality and uniformity of fruit production, as well as disease resistance, which are present in commercial hybrids derived from a favorable heterotic effect on the expression of these traits (Nascimento et al, 2004;Charlo et al, 2011). Favorable heterotic effects have been observed in Capsicum for agronomic and productivity traits (Butcher et al, 2013;Singh et al, 2014). Bhutia et al (2015) observed positive heterosis for yield per plant and content of carotenoids, vitamin C, and capsaicin.…”

ABSTRACT. In Brazil, cultivation of hybrid plants comprise near 40% of the area grown with vegetables. For Capsicum, hybrids of bell and chili peppers have already exceeded 50% and over 25% of all are commercialized seeds. This study aimed to evaluate new pepper hybrids in two environments, Cáceres, MT, and Campos dos Goytacazes, RJ, Brazil. Nine experimental hybrids of C. baccatum var. pendulum were tested and trials were performed in a randomized block design, with three replications and eight plants per plot. In each environment, plants were assessed for canopy diameter, plant height, number of fruit per plant, mean fruit mass per plant, fruit length and diameter, pulp thickness, and content of soluble solids. Seven of the eight traits have differed significantly due to environment variation. Furthermore, genotype and environment interaction was highly significant for number of fruit per plant, mean fruit mass per plant, fruit length, and fruit diameter. Choosing a hybrid to be grown in one of the studied locations must be in accordance with the sought characteristics since there is a complex interaction for some studied traits.
