“…This variation among hybrid groups is important to meet diverse consumer market demands (Lin et al, 2013). The shape and size are important traits when purchasing for Capsicum fruits, varying with consumer's age (Onoyama et al, 2010;Paulus et al, 2015).…”

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.

“…O rendimento de dihidrocapsaicina por planta não apresentou efeito significativo em função das doses de CO 2 . A proporção de capsaicina nos frutos é maior que a de dihidrocapsaicina (Estrada et al, 2002;Nwokem et al, 2010;Paulus et al, 2015) comportamento também observado neste trabalho em relação a estas variáveis. Em experimento com 12 cultivares de Capsicum, observou-se que a variedade Tabasco apresentou elevado teor de capsaicina em relação à dihidrocapsaicina e a ausência de β-caroteno nas condições ambientais estudadas (Guiffrida et al, 2013).…”

Concentration of capsaicinoids in Tabasco pepper with doses of CO 2 applied via irrigationThe study was performed to evaluate the effects of different doses of carbon dioxide (CO 2 ), applied through drip irrigation in determining the concentration of capsaicin and dihydrocapsaicin in the fruits of hot pepper cv. Tabasco (Capsicum frutescens). We aimed to obtain hotter fruits and greater production of these substances for the market of spicy sauces. The experimental design was a randomized block with 4 treatments and 8 replications. Twenty pepper fruits were collected at full maturity, red colored, before the start of wilting, totaling 12 samples. For each sample, two replications of capsaicin and dihydrocapsaicin were analyzed. Analyses were performed by liquid chromatography with ultraviolet detection in CROMA in USP-São Carlos. The concentration of capsaicin in fruits reduced as the applied concentration of CO 2 increased, up to a minimum value of 297 mg/kg of fruits for 123.8 g CO 2 /L. The same behavior was observed in relation to dihydrocapsaicin, with a minimum of 108.46 mg/kg of fruits for 123.8 g CO 2 /L. This means that the higher the CO 2 concentration applied via drip irrigation water, the lower the analyzed capsaicinoids concentration on fruit. However, since productivity increases with increasing CO 2 doses, the total yield of these substances per plant was higher, even though it did not provide an increase in the concentration of these capsaicinoids in fruits.

Few Calabrian pepper cultivars (C. annuum and C. baccatum) are available in the Brazilian market, and among these, only BRS Mari (C. baccatum) was developed in Brazil, by Embrapa. This work aimed to report on the introduction of germplasm in a sui generis way and the initial results of Calabrian pepper breeding at Embrapa Vegetables. Original population was obtained through separation of seeds found in dehydrated Calabrian pepper flakes imported from India. The breeding method was individual selection of plants with progeny test and three generations of selection and self-pollination were advanced. Ten plants were obtained from the original seeds, which were self-pollinated and originated 87 S1 plants. Out of these, seeds of 73 S1 plants were obtained and gave rise to 73 S2 lines. Based on the characteristics of plant and fruit (number of side shoots, weight and total number of fruits, length and width of fruits, wall thickness, color of the ripe fruit, total soluble solids and capsaicin content), three S2 lines were selected and, then, 14 plants within these lines (4 plants of line CNPH 50.112, 5 plants of CNPH 50.116 and 5 plants of CNPH 50.185). Significant differences (Tukey, p<0.05) were noticed among the 14 S3 lines, for precocity, length and width of the fruit, weight of the fruit, weight and number of fruits per plant. Five S3 lines were selected based on the following criteria: average fruit weight above 12 g, early flowering (less than 80 days after sowing), fruit length above 13 cm and fruit width around 1.5 cm, dark green color of leaf and sparse or medium pilosity. In the following S4 generation, the selected lines will be evaluated in order to determine yield, disease resistance as well as capsaicinoid concentration in fruits. New genotypes selected may be released as cultivars that meet the growing demand for dehydrated Calabrian pepper flakes.
