“…This infers that breeding for yield and its contributing traits will not only require parents holding higher GCA values, in addition to specific hybrid combinations that will result in the expression of the trait. The present results are also in accordance with the outcomes of Gopalakrishna et al [37], Shukla et al [38] and Bhutia et al [30]. However, additive gene effects were also reported for this trait [23,39].…”

“…The positive and negative heterosis was determined for ten characters. Heterosis over mid-parent has also been reported for fruit traits and yield components in chilli peppers, as well as in other members of the Solanaceae [15,17,30].…”

“…Previously, in chilli pepper, Hasanuzzaman et al [29] reported the non-additive genetic control of plant height. Bhutia et al [30] also observed non-additive gene effects for primary branches plant −1 , days to first flower, fruit length, fruit girth and seeds fruit −1 .…”

Chilli pepper is commercially cultivated as a spice and is also used for the extraction of a colouring agent. Here, we performed a diallel genetic study involving five chilli pepper varieties. Parents and their hybrid were evaluated for fifteen morphological and five biochemical traits over two crop seasons under open field conditions. Variation was recorded for all of the studied traits. Similarly, significant values for general combining ability (GCA) and specific combining ability (SCA) variance were obtained for all of the traits. The ratio of σ 2 SCA/σ 2 GCA indicates that non-additive gene effects were predominant for all the studied traits except for fruits plant −1 . Based on SCA effects, cross combinations P2 × P5, and P4 × P5 were determined excellent for flesh thickness, yield components and vitamin C. These hybrids are recommended for multilocation testing to assess their suitability for commercial cultivation. Overall, this work presents useful information regarding the genetics of important morphological and biochemical traits in chilli pepper.

“…Favorable heterotic effects have been observed in Capsicum for agronomic and productivity traits (Butcher et al, 2013;Singh et al, 2014). Bhutia et al (2015) observed positive heterosis for yield per plant and content of carotenoids, vitamin C, and capsaicin.…”

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.

“…Additionally, as the chilli domestic consumption needs, the production of chilli and its products are exported to other countries. Thailand, India, China, Pakistan and Peru are the largest dried chilli producers in the world (Bhutia et al 2015). In 2014 Thailand exported chilli with the commercial values of 15,449 tons.…”

Use of dimethyl sulfoxide (DMSO) as a suitable extraction solvent under the optimum conditions of microwave assisted extraction (MAE) prior to total phenolics determination and antioxidant activity assay was conducted. The MAE method was done with 0.05 g sample in 10 mL DMSO at 500 W within 5 min. The effects of DMSO on various antioxidant activities using DPPH(·+), DMPD(·+), ABTS(·+) and FRAP, and Folin-Ciocalteu reagent were investigated. From the results, it is clearly demonstrated that the DMSO itself shows no effect on any of those antioxidant assays including total phenolics content. The DMSO extracts of 14 local chilli varieties gave their antioxidant activities in the following ranges: DPPH, 3.07-20.0; DMPD, 1.52-6.61; ABTS, 20.4-56.0; FRAP, 8.98-42.1 mg GA/g DW. Their total phenolics contents were found in the range of 53.7-200 mg GA/g DW. This study demonstrates that DMSO was found as the most suitable extraction solvent for antioxidants and phenolics from chilli. In addition, analysis of the data obtained among four antioxidant activity assays with respect to total phenolics shows a highly significant and positive regression coefficient (r > 0.92), indicating the total phenolics are primarily responsible for their antioxidant activity of the chilli extract.
