“…The DMC trait showed greater contributions from the additive × dominant genetic effect (Table 3), hybrid vigor should be by exploiting heterobeltiosis to higher values for the trait, increasing significantly the paprika production (Lasmar et al 2019).…”

This study was conducted to identify the allelic interactions and genetic effects involved in genetic control of quantitative traits in Capsicum annuum. Six generations (P 1 , P 2 , F 1 , F 2 , BC 1 and BC 2) were used to study the variances, means and allelic interactions of 16 quantitative traits evaluated. The additive part of the phenotypic variance found for plant height, number of peppers per plant, days to flowering and days to fruiting lead to the conclusion that phenotypic selection in the F 2 generation are likely effective in obtaining genetic gains. According to the reduced model, the traits of canopy width, fruit width and number of seeds per fruit were not influenced by epistatic effects, but only by additive and dominant effects, which allows selection of superior individuals in segregating generations or improvement of these traits by means of hybridization.
