Las técnicas moleculares vienen siendo muy utilizadas en programas de mejoramiento genético del café para la identificación de fuentes de resistencia a la roya amarilla, sin embargo, debe ser considerado el estudio de la estructura y evolución de las poblaciones del hongo, con la finalidad de determinar el tipo de estrategia de mejoramiento genético que debe utilizarse para la generación de nuevas variedades de cafetos resistentes a esta enfermedad.

The high Andean grass Jarava ichu (Poaceae) plays a vital role in water regulation and aquifer recharge. However, its limited use is often linked to forest fires, highlighting the need for sustainable alternatives. Therefore, this study aims to explore the valorization of ichu as a substratefor the cultivation of Pleurotus spp. (P. citrinopileatus, P. djamor and P. ostreatus) and to evaluate the potential of the residual substrate as a biofertilizer, offering an ecological alternative to grassland burning in the Peruvian Andes. Samples of ichu from the district of Tomás (Lima, Peru) were used as culture substrate, analyzing productivity indicators such as crop cycle (CC), biological efficiency (EB) and production rate (PR), together with the nutritional profile of the fungi and the chemical properties of the residual substrate. The results showed an average biological efficiency of 19.8...
