Big chili has the largest fruit size compared to other types of chili. In addition to having a spicy taste, big chilies contain other beneficial biochemicals such as phenolics, flavonoids, antioxidants, and α-glucosidase inhibitors that have the potential to be developed for functional tropical plants. Information on the content is still not widely found. Therefore, this study identified biochemical compounds (TPC, TFC, DPPH, FRAP, AGI) in several genotypes of big chili peppers. From October to November 2021, we conducted a study using the microplate reader method. We repeated the experiment three times. The research design used was a completely randomized design with a single factor genotype. A total of 22 genotypes of big chili were used in this study. The big chili genotype F6074136-2-3-2-3 had the highest content of α-glucosidase inhibitor and antioxidant FRAP compared to other genotypes 67.62% and 71.20 mol TE/g extract. The genotypes CK 12 and F6074077-1-1-3-1 indicated the highest phenolic and flavonoid contents. The correlation between biochemical parameters showed that TPC-AGI and TPC-DPPH were significantly negatively correlated. The conclusion is that the information in this study can be the basis for the development of functional tropical plants in future research.

“…formation of heterotic pools). Heterotic breeding has become a major target for quality trait improvement in other solanaceous crops including chilli pepper (Herath et al 2020), eggplant (Kumar et al 2020), and tomato (Frankel 1983). This is where potato meets an interesting intersection between the vegetable and agronomic worlds where SCA might play a more valuable role for qualities controlling specific market criteria (e.g.…”

Hybrid potato breeding has become a novel alternative to con-ventional potato breeding allowing breeders to overcome intractable barriers (e.g. tetrasomic inheritance, masked deleterious alleles, obligate clonal propagation) with the benefit of seed-based propagule, flexible population design, and the potential of hybrid vigour. Until now, however, no formal inquiry has adequately examined the relevant genetic components for complex traits in hybrid potato populations. In this present study, we use a two-step modelling approach to estimate the relevant variance components to assess the magnitude of the general and specific combining abilities (GCA and SCA, respectively) in diploid hybrid potato (DHP). SCA effects were identified for all yield components studied here warranting evidence of non-additive genetic effects in hybrid potato yield. However, the estimated GCA effects were on average two times larger than their respective SCA quantile across all yield phenotypes. Tuber number GCA’s and SCA’s were found to be highly correlated with total yield’s genetic components. Tuber volume appearing under-selected in this population. The prominence of additive effects found for all traits presents evidence that breeders can perform hybrid potato evaluation using the mid-parent value alone. Heterotic vigour stands be useful in bolstering simpler traits but this will be very dependent on the target market of a population. This study represents the first diallel analysis of its kind in diploid potato using material derived from a commercial hybrid breeding programme.

“…C. annuum , C. frutescens , C. chinense , C. baccatum , and C. pubescence , showed vigor for different traits like fruit yield, plant growth, and earliness ( Sood and Kumar, 2010 ; Shrestha et al., 2011 ; Singh et al., 2014 ; Gözen et al., 2018 ). Heterosis breeding has been extensively used in Capsicum crop to increase the production of economically important traits ( Herath et al., 2021 ). A recent study reported the expression of higher capsaicinoids and sugars in heterotic hybrid (derived from crossing between C. chinense x C. frutescens ) as compared to their parental lines ( Zamljen et al., 2020 ).…”
