Jojoba is a shrub native to the Sonoran Desert, introduced in other countries because the seed contains a liquid wax for use in the cosmetics, lubricants, pharmaceutical industries and with potential in medicine. The purpose of this work was to know the variability of female jojoba plants native to Baja California Sur, Mexico, through morphological characters of a plantation under drip irrigation conditions. In the study we considered 18 morphological variables of the plant, seed and leaves. We performed a descriptive analysis of each variable and a cluster analysis for the conformation of groups of variability and later a canonical discriminant analysis to determine the variables with the greatest influence on the variability between the groups. High variability was found among female jojoba plants, which were agglomerated in five groups; the characteristics of slenderness index and seed width, perimeter and Feret diameter of the leaves and the major diameter and average diameter of the crown of the plants were the most discriminant variables. Also, it was found that group III is the most promising for selection of outstanding genotypes.
