Evaluación de las líneas diferenciales de Avena Sativa L. frente a Puccinia Graminis f. sp. Y Puccinia Coronata f. sp. en el sector de Querochaca

Abstract

In Ecuador, the production of Avena Sativa L. is extremely important for the food and fodder industry in the livestock sector, however, the profitability of the crop is affected by diseases known as rust. In the present investigation, the resistance of the differentiated lines of oats against the diseases produced by Puccinia graminis f. sp. avenae E.&H. and Puccinia coronata f. sp. avenae P.Syd.&Syd. Fifty-two differential lines were analyzed, which were evaluated from day 104 to day 174 of the crop in the heading stage, in four moments whose dates were November 1, November 24, December 1, 2022, and finally January 8 of this year. As a conclusion of this research project, it was determined that the differential lines with the genes: Pc94, MN841801, CDC Orrin, CDC, Sol-fi, HiFi, OT3039, Souris, Stainless, Summit, were the most resistant against the two diseases. with low levels of severity and high performance. For its part, the Oat 24 line with the Harmon gene reached an estimated productivity of 12,733 tons/ha, being the line with the highest grain yield.
