“…Rêgo et al (2012) evaluated pepper plants with ornamental potential and found means of 50 days to flowering and 91 days to fruiting. Silva et al (2020) evaluated promising materials for ornamental use and found 85 days to flowering and 103 days to fruiting for the earliest genotype. These are similar results to those found in the present study.…”

Ornamental peppers have a significant economic importance in the national and international markets; however, few cultivars intended for this purpose are grown in Brazil. The objective of this study was to select partially inbred lines (PIL) of peppers with ornamental potential, based on quantitative and qualitative variables with high heritability. The study was conducted over six generations for 4 consecutive years, using the single seed descent method. The last phase (VI) consisted of growing plants of the F5 generation for selection. Qualitative (LD) and quantitative (QD) descriptors were considered and the ideal genotypes were defined. The statistical analyses consisted of estimating variance components and genetic parameters and predicting genetic values, using REML/BLUP for QD, except for cycle to flowering (CF) and cycle to maturation (CM), which were analysed qualitatively. Therefore, CF and CM were analysed through frequency distribution of continuous variables within class intervals. Descriptive statistics were used to evaluate LD. The results showed that residual values exceeded genetic values, resulting in low heritability for QD, and therefore, they were not considered for PIL selection. Regarding LD, genetic variability was found among the population genotypes for all evaluated descriptors. The selection based on ideal genotypes enabled the selection of 82 PIL with LD of high ornamental value, which differ from the materials already available on the market. The selected genotypes will be used for developing future generations until allele fixation, focussed on subsequent selection of candidate lines for new ornamental pepper cultivars.

“…Very tall plants with a wider crown do not adapt well to the pot, resulting mainly in the plants tipping over. Very small plants end up not standing out on the pot, directly compromising the aesthetics and visual balance (Silva et al, 2020). The evaluation of these parameters is traditionally carried out when the rst fruits ripen, using a ruler and caliper (IPGRI et al, 1995).…”

Being capable of accurately predicting morphological parameters of the plant weeks before achieving fruit maturation is of great importance in the production and selection of suitable ornamental pepper plants. The objective of this article is evaluating the feasibility and assessing the performance of CNN-based models using RGB images as input to forecast two morphological parameters: plant height and canopy diameter. To this end, four CNN-based models are proposed to predict these morphological parameters in four different scenarios: first, using as input a single image of the plant; second, using as input several images from different viewpoints of the plant acquired on the same date; third, using as input two images from two consecutive weeks; and fourth, using as input a set of images consisting of one image from each week up to the current date. The results show that it is possible to accurately predict both plant height and canopy diameter. The RMSE for a forecast performed 6 weeks in advance to the actual measurements was below 4.5 cm and 4.2 cm, respectively. When information from previous weeks is added to the model, better results can be achieved and as the prediction date gets closer to the assessment date the accuracy improves as well.

“…Nos últimos tempos, a maior parte do mercado de pimentas é integrada ao comércio de produtos alimentícios, incluindo formas in natura e processadas, como molhos, conservas, geleias, pápricas, corantes e aromatizantes (SILVA et al, 2020;VÁZQUEZ-ESPINOSA et al, 2020). Além disso, por meio do cultivo, é possível gerar outros produtos para atender várias demandas do mercado, como plantas ornamentais, repelentes de insetos, sprays de autodefesa e compostos benéficos para a saúde (FERRAZ et al, 2016;VÁZQUEZ-ESPINOSA et al, 2020).…”
