Peronospora farinosa, f. sp. chenopodii. in quinoa (Chenopodium quinoa. Will) aspects of epidemiology and resistance
Using 60 quinoa accessions and 20 downy mildew isolates, a scale for scoring quinoa downy mildew was developed, 4 virulence groups and 3 resistance factors were identified. Genotypes ECU-291, ECU- 470, ECU-379 and ECU-288 are proposed as a prelimirfaTry quinoa differential set for identifying quinoa downy mildew virulence groups. Two types of hypersensitivity were identified in this study. "Highly hypersensitivity" (Reaction type 0) , characterized by absence of perceptible necrosis and "delayed hypersensitivity" (reaction type 1), characterized by visible necrosis.
