“…Other studies corroborate the results found in this work, showing that additive gene effects are predominant for water loss [12], fruit length [34][35][36], fruit width [35,36], and for fruit wall thickness [37]. On the other hand, some studies have shown that dominant variation is the predominant gene effect for TSS [18,21] in peppers.…”

“…Overall, genitors 4, 24, 50, and 56 should be selected to form new populations to improve these traits. On the other hand, a previous study with different varieties of Capsicum baccatum indicated only one cultivar, i.e., 'BRS Mari', as a good combiner in a genetic effects study [21].…”

“…In this study, good general combiners showed no better average performance, indicating that the parent should be selected based on estimates of general combining effects (g i ) and not by mean performance. To advance generations in a breeding program based on hybridizations methods, parents with good general combining ability for the target trait must be selected [18,21]. In order to reduce water loss during the selection process, in the successive self-fertilization generations, it is necessary to select a hybrid that has one of the parents with negative g i estimates, such as parents 4 and 58.…”

“…The crosses presenting desirable specific combining ability along with good general combining ability could be used in breeding programs [18]. Knowledge of the gene action of plant traits is essential for the advance of effective breeding programs [21], alongside studies of hybridization and the heterotic vigor of diallel mating design [22], helping breeders to choose the appropriate improvement method [21,22].…”

The objective of this study was to evaluate the genetic effects involved in post-harvest water loss of C. baccatum fruits and to correlate fruit morphological characteristics. Fruits of eight landraces of C. baccatum and their twenty-eight hybrids were evaluated in a randomized, complete block design. Analysis of variance, diallel analysis, phenotypic and genotypic correlation, and path analysis for eight fruit traits were performed. Fruit width, fruit length, dry matter content, and fruit wall thickness were determined by additive gene effects. On the other hand, the non-additive effects played more important role than additive ones, including water loss, cuticle thickness, exocarp thickness, and total soluble solids. The relationship of fruit traits suggested that indirect selection can be carried out from field experiments under different environmental conditions. Overall, genitors 4, 24, 50, and 56 should be selected to form new populations to improve these traits. The Brazilian pepper landraces of C. baccatum species are a source of genetic variability for plant breeders, and the new segregating populations emerging through the crossing of pepper lines with reduced water loss should be developed, opening new ways for conventional breeding.

“…Total phenolic content was determined according to Gomes et al (2021) . The samples (0.5-g fruit pericarps for each) were extracted in methanol (1:10), and the phenolic content was measured spectrophotometrically based on its reaction with Folin-Ciocalteu reagent.…”

Modulated Light Dependence of Growth, Flowering, and the Accumulation of Secondary Metabolites in Chilli

et al. 2022

Chili is widely used as a food additive and a flavouring and colouring agent and also has great importance in health preservation and therapy due to the abundant presence of many bioactive compounds, such as polyphenols, flavonoids, carotenoids, and capsaicinoids. Most of these secondary metabolites are strong antioxidants. In the present study, the effect of light intensity and spectral composition was studied on the growth, flowering, and yield of chilli together with the accumulation of secondary metabolites in the fruit. Two light intensities (300 and 500 μmol m–2 s–1) were applied in different spectral compositions. A broad white LED spectrum with and without FR application and with blue LED supplement was compared to blue and red LED lightings in different (80/20 and 95/5%) blue/red ratios. High light intensity increased the harvest index (fruit yield vs. biomass production) and reduced the flowering time of the plants. The amount of secondary metabolites in the fruit varied both by light intensity and spectral compositions; phenolic content and the radical scavenging activity were stimulated, whereas capsaicin accumulation was suppressed by blue light. The red colour of the fruit (provided by carotenoids) was inversely correlated with the absolute amount of blue, green, and far-red light. Based on the results, a schematic model was created, representing light-dependent metabolic changes in chilli. The results indicated that the accumulation of secondary metabolites could be modified by the adjustment of light intensity and spectral composition; however, different types of metabolites required different light environments.
