The objective of this research is to obtain the best substrate for the multiplication of mycorrhizal from tropical soils of Ecuador. Inoculated with mycorrhizal strains LMSSK, obtained for research purposes from the Canary Institute of Agricultural Research ICIA of the Canary Islands - Spain and native mycorrhizal obtained from the native cocoa garden of the Maquita Foundation. Three mixtures of substrates were made using earth, coconut peat and "stone" picon. The seeds were disinfected before sowing, inoculating directly to the hole, for 90 days in the pots. The experiment consisted of 6 treatments plus one control (unsterilized soil) in four repetitions. The variables to be evaluated were the level of colonization of native mycorrhizal and LMSSK in trap plants, determination of the volume and weight of the root system of trap plants, under the effect of mycorrhizal, multiplication of spores for native mycorrhizal and LMSSK in flat trap and the effect of mycorrhizal to the morphological changes of sorghum (Sorghum bicolor L) and basil (Ocimum basilicum). The results obtained were that the most suitable substrate for mycorrhizal multiplication is given by the substrate soil + coconut peat + picon, with colonization rates between 80 and 99 %, recording the native strain of the cocoa orchard with 2350 spores in 100 g/soil and the strain LMSSK with 2390 spores in 100 g/soil, having both strains equal colonization and multiplication capacity.
