ESCALERA-ORDAZ, Ana Karen et al. Characterization of cultivated varieties of Capsicum pubescens in Michoacán, Mexico. Rev. Mex. Cienc. Agríc [online]. 2019, vol.10, n.spe23, pp.239-251.  Epub Nov 20, 2020. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v0i23.2024.

The state of Michoacán has diverse homogeneous agro-ecological zones that favor the wide diversity of plant species, which includes the cultivation of chili, considered one of the main crops worldwide. The cultivation of C. pubescens has gained greater importance in recent years due to the increase in its production. This species has broad genetic variability that can be used in breeding programs. However, the variability in the state of Michoacán has not been sufficiently documented, so the genetic potential it represents is unknown. In the present work, the collection and morphological characterization of cultivated varieties of C. pubescens in different agroecological zones was proposed in order to evaluate the morphological variability and relate it to the different existing agro-ecological conditions. The in situ morphological characterization was made based on the descriptors proposed by IPGRI, AVRDC and CATIE and UPOV, the evaluation included 27 characteristics of leaf, fruit and seed. The results obtained indicate that there is a wide variability in the cultivated varieties of C. pubescens. Likewise, the fruit characteristics were identified as the most important to discriminate the varieties with potential to be used, as quality parameters, in breeding programs. Finally, no relationship was found between the morphological variability of C. pubescens and the sites of origin of the cultivated varieties.
