“…The evaluated hybrids yield around 5 and 11 t/ha, with a productive potential of 20 t/ ha under suitable harvesting conditions and two of their parents resistant to PepYMV (Bento et al, 2009;Medeiros et al, 2014).…”

“…However, being aware of this reality, researchers have intensified efforts on studies with peppers of the species C. baccatum. Among them, there are studies on phenotypic diversity characterization (Rêgo et al, , 2015Leite et al, 2016), diallelic analysis and correlation between quantitative traits (Gonçalves et al, 2011;Rodrigues et al, 2012;Medeiros et al, 2014;Rêgo et al, 2009Rêgo et al, , 2015, inheritance of resistance to Pepper yellow mosaic virus -PepYMV (Bento et al, 2013), new cultivars resistant to PepYMV (Oliveira et al, 2015), reference map building (Moulin et al, 2015b), and dissection of QTLs for agronomic traits (Moulin et al, 2015a).…”

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.

“…The GCA variability allows us to infer that the parents contributed differently at the crosses involved [30]. Medeiros et al [33] evaluating the genetic and heterosis effects in crosses of C. baccatum, selected the characteristics with greater general combining ability (ĝi) according to the characteristics of interest.…”

The study was carried out with the objective of estimating the combinatorial capacity of ornamental pepper (Capsicum. annuum L.) genotypes for flower traits, aiming to identify the best hybrids and the best parents for the synthesis of new populations. The experiment was conducted in a greenhouse in the . Seven accessions of Capsicum annuum were hand-crossed. Seven flower traits were evaluated including days for flowering, flower diameter, petal length, number of petals, number of stamens, anther length, and filament length. The diallel analysis using the Griffing method I of the data recorded showed that accessions 001, 004 and 099 were the best for flower characteristics based on their GCA values. There were significant reciprocal effects for JEAI, 31(4): 1-8, 2019; Article no.JEAI.46755 2 days to flowering, filament length and anther length. The additive effects of the genes were predominant for most of the flower characteristics and the non-additive effects for the days for flowering only. Genotypes 001, 004 and 099 are indicated for crosses that aim to increase flower characteristics. In general, these genitors were involved in almost hybrids combinations with best SCA values. Those combinations should be used for to advance genarations in the breeding program. On the other hand, the best hybrids to be release for propagation were: 134 x 004, 137 x 001, 390 x 004, 77.3 x 099, 001 x 390, 001 x 77.3, and 099 x 77.3. Original Research Article
