All rights reserved.This study¿s objective was to evaluate the physicochemical properties and yield of chiltepin fruits (Capsicum annuum var. glabriusculum) cultivated under three different growth conditions: greenhouse, mezquite (Prosopis sp) stands, and wild type. The yield of chiltepin fruits collected under greenhouse conditions was higher than mezquite stands (2.34-times). Likewise, fruits from greenhouse had a higher pH (6.0), the wild type and mezquite stands (pH = 5.5) chiltepin fruits. The numbers of seeds of chiltepin fruits cultivated in greenhouse and mezquite stands conditions were higher in comparison to wild type fruits (1.75-fold). However, mezquite stands and wild type chiltepin fruits showed 1.25 times higher acidity (% citric acid) than fruits cultivated in greenhouse conditions. Furthermore, the chiltepin fruit from mezquite stands was higher in the +a (red) color parameter (2.36-times) than wild type fruits. These results showed that chiltepin fruits from mezquite stands presented the best physicochemical properties and red color, thus, this growth condition could serve as germplasm banks for the production of seed form Capsicum annuum var. glabriusculum of good quality, and for the further establishment of new plantations of chiltepin species in the northwestern of Mexico.
