IntroductionOrnamental peppers (Capsicum annuum L.) have the advantage of multipurpose use in fresh, spice, and pickle consumption, besides being pot and garden plants and cut flower arrangement species. Lately, interest and demand for ornamental peppers has increased. According to Stommel and Bosland (2006), ornamental peppers have begun to regain their previous popularity due to easy seed propagation, relatively short cropping time, and heat/ drought tolerance. The varied foliage color and colorful fruits characterizing ornamental peppers ensure a vivid summer garden display that rivals the chrysanthemum (Dendramthema grandiflora Tzvelev) for brilliant fall color (Stommel and Griesbach, 2005).Steadily growing interest has encouraged intensive breeding studies of ornamental peppers. When evaluated in terms of method, it was seen that the majority of these studies (

“…Probably, this major contribution is due to the fact that some populations naturally present different rates of development of plant canopy. According to Barbosa et al (2002), Stommel and Bosland (2006), and Barroso et al (2012), plants with compact size, lower height and smaller canopy diameter are of interest for selection of pepper plants with ornamental use purpose.…”

“…Furthermore, it is important to consider the relationship between plant architecture and vase size. The plant height and canopy diameter should be 1.5 to 2 times larger than the size of the vase (Barbosa et al, 2002;Barroso et al, 2012).…”

The genus Capsicum presents a wide genetic variability. The most common way to determine this variability has been based upon morphological descriptors. We studied the genetic divergence among populations of ornamental pepper (Capsicum annuum L.) using two different multivariate techniques: Cluster analysis and canonical discriminant variables. The analyses enabled us to determine the morphological descriptors that contributed most to the genetic divergence. The study was carried out in a greenhouse in the Northeastern Brazil, in two years: 2013 and 2014. The experimental design was the completely randomized design, considering two crossed factors: Population and years. Thirteen populations of ornamental pepper were evaluated based on sixteen plant descriptors, six flower descriptors and ten fruit descriptors; eight F 3 populations, resulting from crossing the accessions 134 (P-9) and 77.1 (P-10), and five additional control populations: P-9, P-10, P-11, P-12 and P-13. There was an agreement between the two multivariate techniques in terms of distance between populations. Fruit descriptors contributed most to the genetic divergence, separating the populations used as control (P-11, P-12 and P-13) from the others. This separation is due to the uniformity of these populations in terms of fruit size and weight.

“…Fast-growing pepper seedlings may be transplanted earlier, decreasing production costs and time (Barroso et al 2012). Less vigorous plants can lead to death and affect the plant stand causing profit loss to nursery owners.…”

The genus Capsicum is cultivated in various parts of the world, with C. annuum showing high diversity and potential for ornamental purposes and genetic improvement. The aim of this work was to evaluate the combining ability and heterosis of seedling and plant traits in accessions of ornamental pepper and their hybrids. Seven accessions of C. annuum were handcrossed and twelve quantitative plant traits were evaluated. The data were subjected to analysis of variance, the Scott-Knott test and diallel analysis using Griffing's method I (fixed model). Heterosis and its components were also determined. Non-additive effects were found for seedling height, cotyledonous leaf length and width; stem diameter and chlorophyll b content. All other traits showed predominance of additive effects. Heterosis effects were found for some hybrids and UFPB134 x UFPB137, UFPB134 x UFPB390, UFPB134 x UFPB004 and UFPB099 x UFPB004 showed seedlings that are more vigorous.
