Uno de los patógenos que atenta contra la productividad del cultivo de papa y, por ende, a la seguridad alimentaria de la población es el nematodo fitoparásito Globodera pallida, conocido como el “nematodo del quiste de la papa”. La búsqueda de variedades de papa con genes de resistencia a este nematodo es una alternativa de control para el manejo de esta enfermedad. En la presente investigación se realizaron pruebas de infección, inoculando estadíos juveniles 2 (J2) de G. pallida en raíces de plantas de las variedades María Huanca y Chimbina Colorada, proporcionadas por el Centro Internacional de la Papa (CIP), catalogadas como resistente y susceptible al nematodo, respectivamente. Se evaluaron raíces infectadas a las 24 y 72 horas post - inoculación (pi), mediante la cuantificación bajo microscopio de J2 que ingresaron a la raíz. Además, se realizaron extracciones de ...

The objective of this study was to select and characterize agronomically the advanced bread wheat line H - 1246 which gave origin to the INIA wheat variety 440 - K’ANCHAREQ. The research included yield trials in farmers’ fields during 4 production seasons (2012–2016), adaptation and agronomic efficiency trials in two production seasons (2016–2018). In addition, the reaction to Yellow Rust and distinctness, uniformity and stability characteristics of the new wheat variety and commercial controls were evaluated. The plots for each of the trials were conducted under a Completely Randomized Block design with three replications. At the end of the trials, desirable characteristics in the baking industry such as hectoliter weight, protein, ash, gluten and flour moisture were evaluated. The results showed that the new INIA 440 - K’ANCHAREQ variety has ten clear differences in qualitati...
