    In Ecuador, there are about 350 varieties of native potatoes, cultivated by small farmers above 3,200 masl, which are threatened by low yields, increases in pests, diseases and the promotion of improved varieties. This research evaluated rooting in cuttings of two varieties of native potatoes, Chaucha Amarilla (Solanum phureja) and Mora Azul (Solanum tuberosum), at the Santa Catalina Experimental Station INIAP, located in the Pichincha province, Mejía canton, Cutuglagua parish. A completely random block design (DBCA) was implemented with factorial arrangement A x B; where factor A are the native potato varieties (Chaucha amarilla and Mora azul) and in factor B are the rooting ones (Microalga Spirulina, Aloe vera, Cinnamon and as a witness the Hormonagro 1), so the research has 8 treatments with 3 repetitions giving us a total of 24 experimental units. The evaluated variables were percentage of rooting (%), shoot length (cm), number of roots, root length (cm), and root weight (g) in which was carried out a variance analysis and test Tukey of 5%. By interpreting the results, it was identified that statistically all treatments have the same percentage of adhesion, but, in terms of values, treatment V1E3 (Chaucha Amarilla + Cinnamon) showed the best rooting percentage (93%) and the longest shoot length with an average of (3.96 cm). In the variables related to the root system, the best treatments for the number of roots were V1E4 (Chaucha Amarilla + Hormongro 1) with an average of (9.17); V1E3 (Chaucha Amarilla + Cinnamon) with an average of (9.03); and V1E1 (Chaucha Amarilla + Spirulina Microalgae) with an average of (8.72) the treatment V1E3 (Chaucha Amarilla + Cinnamon) showed a root length of (11.29 cm) and a root weight of (0.39 g). Additionally, there was conducted a cost/benefit analysis of the treatments, and they are considered profitable as they have a value greater than 1. It is established that the application of rooting in the cuttings from mother plants helps to obtain native potatoes seedlings.
