“…Así también, las variables cualitativas pueden ayudar a diferenciar poblaciones locales de chile de las especies C. annuum, C. chinense y C. frutescens (Castillo-Aguilar et al, 2021). Li et al (2022) indican que con descriptores de frutos se pueden diferenciar especies de chile. En chiles silvestres pico de paloma (C. frutescens) in situ, las agrupaciones se realizaron con variables vegetativas como altura y ancho de la planta, largo y ancho de las hojas, diámetro del tallo, además de variables de fruto (largo y peso).…”

Background. Mexico has a great diversity of chili peppers, especially in C. annuum L., which includes local morphotypes that have been little studied. Apaxtleco chili pepper is only found in Guerrero State, Mexico, and it is important in Apaxtla region due to economic resources it generates, and because it is used in preparation of typical mole in this region; however, its morphological diversity has not been described and this visualizes the state of this plant genetic resource to define use and conservation strategies. Objective. To analyze and describe morphological diversity of a group of Apaxtleco chili pepper populations, identify characteristics that most support its diversity and establish similarity relationship between the populations studied. Methodology. Twenty-four populations of apaxtleco chili pepper collected from Apaxtla de Castrejón, Guerrero were evaluated under randomized complete block experimental design, with four replications. The evaluation was carried out under greenhouse conditions at Tuxpan Unit of Autonomous University of Guerrero. Sowing was carried out in July 2020 in polyethylene pots with 16 L capacity. Fifty-nine morphological variables from IPGRI descriptors for Capsicum were recorded, and variance, discriminant, principal components (CP) and conglomerated analysis were performed by SAS V9.3 software. Results. Statistical significant differences were found in 72.9 % of variables registered and seventeen were selected by its contribution to variation according discriminant analysis, which were mostly fruits characteristics. In CP, with the first six, 76 % of total morphological variation was explained; length fruit and pedicel, width seed, weight fruit per plant, color of fruit at intermediate stage, number fruits per plant, width fruit, fruit and seed texture, filament color, number seeds per fruit and shape fruit appendage had greater contribution to total morphological diversity and were useful to differentiate populations under study. As well, four groups of apaxtleco chili pepper with different fruit, vegetative and flower characteristics were identified, however, it was possible to group them by shape and texture of fruits. Implications. Contribute to description of diversity of local populations of apaxtleco chili, native to Guerrero, Mexico, and that allows the establishment of use and conservation mechanisms for food security. Conclusion. Morphological diversity of native apaxtleco chili of Guerrero is presented mainly in fruit characteristics and lesser degree in vegetative and seed traits, which were useful to explain greater total variation in this local chili. The shape and texture fruits were important characteristics in grouping.

“…The average weight of pepper fruit in large-flowered sweet varieties reaches 250-350 g, and often more [13]. Flesh and skin texture, juiciness and postharvest shelf life are determined by both genetic traits and growing conditions [28].…”

The cultivar and fertilization can affect the physicochemical properties of pepper fruit. This study aimed at estimating the content of α-carotene, β-carotene, total carotenoids, and the total sugars of unfertilized pepper and samples treated with natural fertilizers based on texture parameters determined using image analysis. Pearson’s correlation coefficients, scatter plots, regression equations, and coefficients of determination were determined. For red pepper Sprinter F1, the correlation coefficient (R) reached 0.9999 for a texture from color channel B and −0.9999 for a texture from channel Y for the content of α-carotene, −0.9998 (channel a) for β-carotene, 0.9999 (channel a) and −0.9999 (channel L) for total carotenoids, as well as 0.9998 (channel R) and −0.9998 (channel a) for total sugars. The image textures of yellow pepper Devito F1 were correlated with the content of total carotenoids and total sugars with the correlation coefficient reaching −0.9993 (channel b) and 0.9999 (channel Y), respectively. The coefficient of determination (R2) of up to 0.9999 for α-carotene content and the texture from color channel Y for pepper Sprinter F1 and 0.9998 for total sugars and the texture from color channel Y for pepper Devito F1 were found. Furthermore, very high coefficients of correlation and determination, as well as successful regression equations regardless of the cultivar were determined.
