“…Therefore, two evaluated molecular markers had high association between pungent phenotype and pungent alleles, being SNP marker also efficient in predicting non-pungent phenotype. These results are in accordance with the ones observed by Pereira et al (2015). All C. baccatum var.…”

“…Two specific molecular markers to determine pungency were evaluated: pun1¹ (specific for C. annuum) and SNP (identifies pungency in several Capsicum species). Marker amplifications (reagent concentrations and thermocycler programming) and the analysis of the obtained fragments were performed according to Pereira et al (2015). As a negative control of pungency, tomato (Santa Clara), eggplant (F 1 Ciça) and okra (Santa Cruz 47) samples were used.…”

Peppers of the genus Capsicum are of great socioeconomic importance, being pungency trait their main attraction. Pungency characterization, genetic distance estimates and population structure analysis of the accessions belonging to germplasm banks are important for parent selection which allows to obtain superior progenies. Therefore, the aims of this study were: i) evaluate 81 accessions of the Capsicum spp. Germplasm Bank of Universidade Federal de São Carlos (BGC-UFSCar) with molecular markers linked to pungency; ii) estimate the genetic diversity among accessions of the BGC-UFSCar using microsatellite markers (SSR); and iii) evaluate the efficiency of these markers in the distinction among species of Capsicum spp. We noticed that pun1 1 and SNP molecular markers were efficient in predicting the pungent phenotype of BGC-UFSCar accessions in 84.85% and 95.59%, respectively. From a total of 13 amplified microsatellite markers, seven were polymorphic and efficient to discriminate species of Capsicum genus, both through genetic diversity analysis and population structure analysis, which showed three subpopulations. The molecular markers used in this study are useful tools for breeding programs since they were able to characterize and discriminate Capsicum spp. species at DNA level. Information obtained with molecular markers can assist in the selection of contrasting parents for future breeding programs.

“…Pepper has significant social and economic importance because it requires a lot of hand labor, fixes the farmer in the field and is a profitable economic activity that integrates the small farmer with industry through conserves and sauces (Rufino and Penteado, 2006). In 2015, the area exploited with pepper in Brazil was approximately 5000 ha with total production of 75,000 tons (Pereira et al, 2015). The state of Minas Gerais is the largest Brazilian producer with about 70% of the total produced, but the biggest pepper consumers in Brazil are the north-eastern states (Ceará, Pernambuco and Bahia), especially for in natura consumption (Ribeiro et al, 2015).…”

The objective of the present study was to identify the effect of kinetin on Capsicum frutescens fruit yield. The research was carried out between October 2015 and September 2016 in the experimental field at the State University of Goiás, Brazil. This region has a tropical climate with a dry winter and wet summer. The experiment was conducted in rainy conditions (without irrigation) in a randomized block design with five treatments (plants submitted to 0, 50, 100, 150, 200 and 250 mg L-1 kinetin in volume of 30 ml/plant/application in a total of two applications at a 40-day interval, started at the R 2 reproductive stage), six replications and the plots consisted of two useful plants. The variables stomata density, specific leaf area, stem and canopy diameter, length and width of completely opened leaves did not fit the linear and quadratic regression models in function of the kinetin doses applied. Kinetin increased fruit drain strength and increased productivity of Capsicum frutescens. Plants treated with this cytokinin showed vigorous vegetative growth and significant increases in concentrations of photosynthetic pigments. The use of kinetin in Capsicum frutescens plants is a promising practice in the management of the species because it promotes morphophysiological adjustments in the plant that increase vegetative vigor and fruit yield.
