The bioprotective effect of three consortia of native arbuscular mycorrhizal fungi was evaluated in seedlings of three Coffea arabica L. varieties, propagated sexually and asexually against the attack of yellow rust (Hemileia vastatrix). The research took place in Chirapa - Lamas, in plant nursery conditions and in the Mycorrhizal fungi Laboratory of IIAP, Tarapoto - San Martín. The Completely Random Design was used with a factorial arrangement of 3A x 2B x 4C, being A: coffee varieties (caturra, pache and nacional), B: propagation method (sexual and asexual) and C: native AMF consortia (provinces of Moyobamba, El Dorado and Huallaga) compared with a witness, resulting in 24 treatments, 9 plants / treatment and 216 experimental units. In the planting out of the seedlings, 1500 native AMF spores were inoculated and a month later they were moved out in the plant nursery of Chirapa in a coffee plantation with a grade 4 of rust, according to SENASA scale (2013). There was a natural infection of rust in coffee seedlings, observing the symptoms in the second month and its increase in the following months. At 180 days after planting, the incidence and severity test indicated that AMF did not have a bioprotective effect against rust; however, the AMF did have favorable results in morphological characteristics: height (cm), number of leaves, leaf area (cm2), aerial and root dry biomass (g), mycorrhizal colonization (%) and extra radical mycelium length (cm), in contrast to the control.
