“…These values are consistent with those observed in the literature, such as 9.28°Brix (Rodrigues et al, 2012) and 10.02°Brix (Oliveira et al, 2015). Interestingly, studies have pointed out that there is a negative correlation between SSC and productivity .…”

“…Regarding canopy diameter, hybrids presented an average of 98.5 cm in environment I and 116.0 cm in environment II, showing a more compact shape than the genotypes assessed by Rêgo et al (2011) (Table 3). This trait has great relevance in this crop management, as most compact canopies facilitate cultural practices and enable a larger number of plants per area, which in turn may reflect in increased productivities (Bento et al, 2007;Rodrigues et al, 2012;Oliveira et al, 2015).

“…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.
