OBJECTIVE. Morphologicall characterization of main wild chilli peppers found in the Campeche state and Yucatan Peninsula: Maax (Capsicum annuum Var Glabriesculum) and Pico Paloma (Capsicum frutescens) chilli pepper. Methodology. Two seed compounds of wild chilli pepper were evaluated, Maax and Pico Paloma, product of a preliminary collection in the State of Campeche. Both ecotypes were evaluated ex situ during 2016 and 2017 under greenhouse conditions. The evaluation was carried out jointly with eight other ecotypes under a randomized block design with three replications. The morphological was based on the characteristics considered in the IPGRI Capsicum descriptor. The morphological cuantitative characterization was based on descriptive statistics. Results. The main differentiating characteristics between the Maax and Pico Paloma chilli pepper were: the shape, length and width of the cotyledonous leaf, shape and margin of the leaf, number of flowers per axil, color and spot of the corolla, number of fruit locules and seed surface. Findings / Conclusions. The morphological characterization allowed to establish structural anatomical differences between the Maax pepper and the Pico Paloma pepper; it also contributed to the knowledge of the ex situ plant growth characteristics and the identification of some characteristics that contribute to the explanation of the morphological variation between the evaluated ecotypes. Objective: To morphologically characterize two wild species of Capsicum annuum Var. Glabriusculum (Maax pepper) and Capsicum frutescens (Pico Paloma pepper). Methodology: Two seed compounds were evaluated, one from Maax pepper and another from Pico Paloma pepper, collected in Campeche, Mexico. Both ecotypes were evaluated ex situ in the 2016 and 2017 cycles, under greenhouse conditions. The evaluation was carried out jointly with eight other ecotypes in a randomized block design with three repetitions. The morphological characterization was based on the Capsicum descriptor of the IPGRI. The ecotypes were characterized and compared based on descriptive statistics. Results: The main differential characteristics were: shape, length, and width of the cotyledonous leaf; shape and margin of the leaf; number of flowers per axil; color and spot of corolla; number of fruit’s locules, and seed surface. Conclusions: The morphological characterization allowed to establish differences between the two genotypes; contributing to the knowledge of ex situ growth characteristics.
