Grapevine (Vitis vinifera L.) varieties are particularly susceptible to the pathogens downy mildew Plasmopara viticola and powdery mildew Erysiphe necator. Conventional methods for identifying and classifying spores rely on time-consuming microscopic examinations susceptible to human error and requiring qualified personnel. The aim of the present w...
A half-diallel cross study of seven melon inbred lines was carried out. The seven parents and their 21 F1 hybrids were evaluated for precocity of maturity, average weight per fruit, and fruit quality (fruit size, rind thickness, and soluble solids). The Diallel analysis was investigated for breeding values of these melon genotypes via general and s...
The present study was carried out to evaluate and characterize, for the first time, the genetic potential of a collection of onion (Allium cepa L.) local accessions from the arid region of southern Tunisia. The genetic diversity among 135 onion individuals, belonging to 23 accessions, was evaluated using microsatellite (SSR) markers and phenotypic...
The preservation of viable pollen is essential to overcome the problems related to the asynchronous flowering of the parental lines in onion hybrid breeding programs. The aim of this study was to establish a simple, inexpensive, and easily reproducible protocol for medium-term onion pollen storage. First, the conditions for assessing the in vitro p...
Peppers are fruits with wide genetic variability and multiple ways of being consumed that hold a relevant position in the human diet. Nowadays, consumers are interested in new gastronomic experiences provided by pepper cultivars that present new shapes, colors, and flavors while preserving their bioactive compounds, such as their capsaicinoids and...
Interest in the consumption of the fruits of pepper (Capsicum spp.) is not only due to its organoleptic characteristics, but also due to its bioactive compounds content, which are reported to provide essential benefits to human health. However, the amount and diversity of these compounds in each fruit specimen depend on its genotype and on a number...
El pimiento pertenece a la familia de las Solanáceas y género Capsicum. Existe un gran interés en cuanto al consumo de sus frutos, ya que estos se consideran una rica fuente de compuestos antioxidantes. Estos compuestos tienen cada vez mayor interés ya que juegan un papel importante en la prevención de enfermedades como el cáncer, la anemia, la dia...
“Naga Jolokia” (Capsicum chinense Jacq.) is a hot pepper variety native to India which has received the attention of the global scientific community due to its high capsaicinoid concentration. The present study evaluated the influence of fruit ripening on the total and individual capsaicinoids, as well as capsiate content. The aim was to determine...
Quantification, using an accurate analytical approach, of capsinoids and capsaicinoids was performed on three chili pepper (Capsicum spp.) genotypes: ‘Chiltepín’, ‘Tampiqueño 74’, and ‘Bhut Jolokia’ at various stages of fruit development. The accumulation of capsinoids, in all these peppers started between 10 to 20 days post-anthesis (dpa), increas...
The evolution of individual and total capsaicinoids content in three pepper varieties of Capsicum chinense Jacq. (‘Bode’ (B), ‘Habanero’ (H), and ‘Habanero Roxo’ (Hr)) during fruit ripening was studied. The five major capsaicinoids (nordihydrocapsaicin, capsaicin, dihydrocapsaicin, homocapsaicin, and homodihydrocapsaicin) were extracted using ultra...
A highly sensitive, selective method has been developed and validated for determination of capsiate and dihydrocapsiate for the first time using HPLC-ESI/MS(QTOF). For both capsinoids, LODs and LOQs were 0.02 and 0.05 µmol/l, respectively. The intra- and interday repeatability values (RSD %) were 0.26-0.41% for retention time, and 2.25-2.11% for pe...
El ‘Chiltepín’ es un chile muy popular en México por su intenso color rojo y su
característico sabor y picor. Este último atributo es debido a la presencia de unos compuestos pertenecientes a las familias de los capsaicinoides y los capsinoides; sus presencias, así como la distinta relación de sus contenidos perfilan un tipo de picor diferencial. A...
Onion (Allium cepa L.) and pepper (Capsicum spp.) have been cultivated for thousands of years due to their medicinal and therapeutic properties. Nowadays, these health-promoting properties have been attributed to the bioactive compounds responsible for the pungency of onion and pepper. The nutraceutical potential showed by cysteine sulfoxides in on...
Capsinoids exhibit health-promoting properties and are therefore compounds of interest for medical and food sciences. They are minor compounds present in relatively high concentrations in only a few number of pepper cultivars. It is desirable to quantify capsinoids to provide selected cultivars with high capsinoid contents, which can then be employ...
El pimiento (Capsicum spp.) es ampliamente valorado en la gastronomía mundial por sus distintas cualidades de sabor y calidad. Además es considerado una rica fuente de compuestos antioxidantes. Estos compuestos tienen cada vez mayor interés ya que juegan un papel importante en la prevención de enfermedades cardiovasculares y de otras como el cáncer...
The ontogenetic variation of total and individual capsaicinoids (nordihydrocapsaicin (n-DHC), capsaicin (C), dihydrocapsaicin (DHC), homocapsaicin (h-C) and homodihydrocapsaicin (h-DHC)) present in Malagueta pepper (Capsicum frutescens) during fruit ripening has been studied. Malagueta peppers were grown in a greenhouse under controlled temperature...
The use of doubled haploid (DH) in onion breeding is limited due to the low gynogenesis efficiency, and more specifically with the South European germplasm. Gynogenesis capacity from Spanish germplasm was evaluated and optimized in this study. Field plants produced a higher percentage of embryogenesis induction than growth chamber plants. A 2 to 3...
Mediante la ginogénesis in vitro se pueden obtener plantas de cebolla doblehaploides (DH), facilitándose así la producción de híbridos estables y de gran vigor. El objetivo del presente trabajo es aumentar las frecuencias de inducción de la ginogénesis y la obtención de plantas DH de cebolla. Se utilizaron tres cultivares españoles: Fuentes de Ebro...
Capsinoids were recently isolated from some sweet peppers as non-pungent compounds similar to capsaicinoids in terms of structure and biological activities.. The structural difference between the capsaicinoids and capsinoids is the way in which the carbon chain is bound to the aromatic ring: by an amide moiety in capsaicinoids and by an ester moiet...
The use of doubled haploids in onion breeding is limited due to the low gynogenesis efficiency of this species. Gynogenesis capacity from Spanish germplasm, including the sweet cultivar Fuentes de Ebro, the highly pungent landrace BGHZ1354 and the two Valenciana type commercial varieties Recas and Rita, was evaluated and optimized in this study. Th...
Los capsinoides, compuestos específicos del género Capsicum, presentan propiedades antioxidantes, analgésicas, etc. Estos compuestos son minoritarios, por lo que es necesario un método analítico preciso para cuantificarlos. Un punto crítico del análisis es la extracción de estos compuestos a partir de una matriz vegetal. El objetivo de este trabajo...

The successful exploitation of germplasm banks, harbouring plant genetic resources indispensable for plant breeding, will depend on our ability to characterize their genetic diversity. The Vegetable Germplasm Bank of Zaragoza (BGHZ) (Spain) holds an important Capsicum annuum collection, where most of the Spanish pepper variability is represented, a...
The evolution of total capsaicinoids and the individual contents of the five major capsaicinoids: nordihydrocapsaicin, capsaicin, dihydrocapsaicin, homocapsaicin and homodihydrocapsaicin present in Bahiana Pepper (Capsicum chinense), during fruit ripening, has been stablished. Bahiana Pepper is a savoury food additive that is widely utilized in Bra...
La cebolla sólo admite dos o tres autofecundaciones debido a la alta depresión por consanguinidad. El poder disponer de protocolos de producción de líneas doblehaploides (DH) de cebolla representa una oportunidad única para la obtención de materiales completamente homocigóticos y estables. De los diferentes métodos de producción de plantas DH, la g...
The substances responsible for the pungency of Capsicum are a group of alkaloids known as capsaicinoid. Recent studies have also revealed the presence of a novel group of non-pungent capsaicinoid-like substances named capsinoids. These compounds have structures similar to capsaicinoids and produce the same biological effects but without the undesir...
