Resistencia de 88 accesiones de quinua (Chenopodium quinoa), a mildiu (Peronospora variabilis), en invernadero y en campo, en Cutuglagua, Estación Experimental Santa Catalina

Abstract

The present research project of I carry ended in the Mejia canton belonging to the province of Pichincha, specifically in the Santa Catalina Experimental Station of the National Institute of Agricultural Research (INIAP), where the main objective of the research was to study the pathogenic variability and evaluate resistance to (Peronospora variabilis) in Chenopodium quinoa accessions from the PRONALEG germplasm bank. To fulfill the aforementioned purpose, 5 seeds of each 88 of the quinoa lines were sown under a greenhouse, to later be inoculated with mildew that were extracted from different sectors, in addition, two tests were carried out in the field, these lines were evaluated for resistance, sporulation and incubation period. The results obtained from the investigation were: the ECU-550 line presented total resistance to fungus from Colta, the LPEQ 3 line was completely resistant to the strain extracted from Lasso and Pillaro sector, while the Tunkahuán, LPEQ 3, LPEQ 4, LPEQ 9 and ECU-507 lines were indicated totally resistant to the strains that came from Píllaro and the lines ECU-531, ECU-552 and ECU-531 presented resistance to the strains obtained from the Santa Catalina Station. Most of the lines showed abundant sporulation and the incubation period ranged between 24 and 36 hours.
