“…In this study, the signi cant differences were founded for most evaluated characters such as fruit length, fruit width, fruit thickness and fruit volume, fruit fresh and dry weight, fruit number per plant, lobes number per fruit and average yield per plant. Signi cant differences between bell pepper or hot pepper genotypes were also observed by other researchers (Naresh et al, 2016;Devi et al, 2018;Aiswarya et al, 2020). Naresh et al (2016) reported the signi cant differences for all traits according to ANOVA analysis in chilli pepper.…”

Hybrid cultivars are commercially and economically important; hence, too much effort needed to improve the quality and quantity of hybrids. In this research project, general (GCA) and specific (SCA) combining ability of 32 doubled haploid (DH) lines of sweet pepper produced via microspore embryogenesis were evaluated. The DH lines were crossed with the top cross parent as the tester to evaluate general combining ability (GCA). Traits including morphological and yield-related characteristics to assess the general combining ability of lines were recorded and analyzed. The half-diallel mating crosses were performed using GCA based on the selected seven DH lines for SCA evaluation. Mean squares of GCA and SCA values were highly significant for most of the characters. DH55 line indicated the highest positive GCA for average yield per plant, moreover, the highest positive SCA was obtained for 55×64 hybrid. The ratio of \(\frac{MS \left(GCA\right)}{MS \left(SCA\right)}\) showed the non-additive gene actions in controlling all traits except fruit width and length and seed fresh weight. According to the results of specific combining ability of DH lines, four F1 hybrids were selected for new cultivar registration. The results obtained in the present study are applicable to release new F1- hybrids, which can be more reliable than those hybrids introduced by conventional selfing programs in sweet pepper due to 100% genetic purity of DH lines.

“…La estimación de los efectos de ACG en los genotipos parentales para características de importancia agrícola puede guiar a la selección de genotipos de chile Guajillo. En el género Capsicum se han reportado efectos significativos de ACG para el rendimiento de fruto por planta (Nagaraju & Sreelathakumary, 2016;Sitaresmi et al, 2010;Do Nascimento et al, 2014;Devi et al, 2018), longitud de fruto y número de semillas por fruto (Singh et al, 2014). La calidad física de semillas mostró una magnitud más amplia en los efectos de la ACG que el vigor de plántula, el análisis de la aptitud combinatoria reveló que ningún progenitor exhibió efectos de ACG para todos los caracteres estudiados.…”

Background. Even though many studies have been done in agronomic characters, there is no knowledge about studies that address the genetic effects on the physical and physiological quality of seeds in native populations of Guajillo chile (Capsicum annuum L.). Objective. The objective of this research was to identify the effects of general combining ability (GCA), and specific (SCA) on seed quality variables, as well as to determine the type of gene action in them. Methodology. F1 and F2 seeds were analyzed from native populations of chili Guajillo through the accelerated aging test and digitization of seed images. Results. The results obtained show that: 1) all the variables were significant for the GCA and SCA, which indicates that the additive and non-additive effects are involved in the genetic control of these characters; 2) In the crosses with the highest average, at least one progenitor with a high GCA effect participated; 3) The effects of GCA were more important than the effects of SCA for the physical quality of seed, length and fresh seedling biomass; 4) In general, heritability in the narrow sense varied from low to moderate (0.00-0.30). Implications. The information generated about the non-additive genetic effect on the quality of Guajillo seed, can be used in breeding programs applying the hybridization technique. Conclusions. There is no relationship between the best crosses and parents with the effects of GCA high. The parents used in this research have acceptable GCA for most traits, crosses with higher SCA values do not necessarily derive from parents with acceptable GCA values.

“…Among the female genitors, only L6, L18, and L19 lines showed positive results, with L6 being the one that expressed the possibility of gain for the three traits -FD (>3 mm), FL (>4 mm), and FM (>30 g). DEVI et al (2018), when assessing 29 genotypes of Capsicum annuum L. var. grossum Sendt., reported positive values of general combining ability for fruit number per plant, concluding that the Sel-1, DARL-10 e UHFSP(Y)-11 lines were the most promising for the increase of fruit yield per plant based on its general combining ability.…”

Estimation of genetic merit of diallel hybrids of sweet pepper by mixed models

et al. 2019

The use of mixed models for evaluating diallel crosses is a highly timely option to the reliable prediction of progeny genetic values. In the sweet pepper crop, hybrids are commercially explored on a large scale, mainly because of their characteristics of economic importance. This study aimed to assess the potential of hybrids obtained from a partial diallel among five sweet pepper lines developed for the hydroponic cultivation system and two simple hybrids, by applying mixed models. It was performed crosses in the partial diallel scheme among the (L1B, L6, L7, L18, and L19) lines and the simple hybrids ‘Valdor’ and ‘Atlantis’. Plants were cultivated in hydroponic system with substrate and irrigated three times a day using nutrient solution. On the basis of mixed models, the following traits were assessed: mean fruit diameter (FD), mean fruit length (FL), mean fruit number per plant (FNP), mean fruit mass (FM), early yield (EYIELD), and mean fruit mass per plant (FMP). The L6 line was the one that showed the highest estimate of general combination capacity for FMP, FM, and EYIELD, proving to be promising for recommendation. The hybrid that provided the best specific combining ability for FD, FM, FMP, and EYIELD was L6 x ‘Valdor’. Triple hybrids were efficient to maximize yield for the traits of interest by the use of the mixed model.
