    The present investigation was carried out at the Technical University of Cotopaxi- Campus Salache in cooperation with INIAP, with the objective of evaluating the agronomic behavior of the promising clones of potato (Solanum tuberosum) INIAP 45 and INIAP 143 against the variety INIAP CIP Libertad in the agroclimatic conditions of the study site, for the present trial a completely randomized block design (DBCA) was implemented with three varieties and three replications with a total of 9 experimental units, the variables evaluated were: percentage of emergence, height, vigor, days to flowering and harvest, number and weight of tubers per plant, yield, tuber uniformity, incidence and severity of purple top, vectors and host plants of purple top, these variables were evaluated according to the manual ‘Potato Breeding: Concepts, procedures, methodologies and protocols’ published by INIAP (2020). A descriptive analysis was applied for which average tables and statistical graphs were structured, the data obtained were analyzed using the INFOSTAT 2.0 software where Tukey tests were applied at 5% for the varieties and repetitions where no statistical significance was found. From the results achieved in the research, the agronomic behavior of the clones INIAP 45 and INIAP 143 in relation to the variety INIAP CIP Libertad was determined, indicating that they all have a similar crop cycle, which suggests good adaptability. In terms of yield, INIAP CIP Libertad outperforms the clones, reaching 1995.12 kg/ha, in contrast to INIAP 45 and INIAP 143. The clone INIAP 143 stands out for its higher tolerance to purple top syndrome compared to INIAP CIP Libertad, which is highly susceptible, showing higher incidence and severity of the syndrome. In addition, cicadas and bugs were identified as vectors of PMP syndrome, along with plants such as Chinese mallow, amaranth and tomatillo del diablo as hosts. Based on this, it is concluded that, although the three have a similar crop cycle in terms of germination, flowering and maturity, the superiority of INIAP CIP Libertad stands out in terms of yield, reaching 1995.12 kg/ha. However, this yield is compromised by its high susceptibility to purple top syndrome, which significantly affects its production.
