| description | In the last years, it has been observed an increasing damage from a viral disease affecting the production and persistence of alfalfa in Argentina. The objective of this work was to compare the incidence and severity of the disease symptoms and to explore the relationship of its dynamics with respect to rainfall (pp) and temperature (T) in six commercial alfalfa cultivars during the period 2010-2014. The cultivars CW1010, WL1058, Traful PV INTA, WL903, Monarca SP INTA and LPS8500 were evaluated in trials at EEA Manfredi-INTA and at EEA Santiago del Estero-INTA. In both trials, mean incidences between 50% and 80% were recorded, with significant interannual variability and differences among cultivars. The severity was higher for the cultivars evaluated in Santiago del Estero. Cultivars WL903 and WL1058 presented the lowest severity, while LPS8500 and Monarca SP INTA showed the highest values. As for the climatic variables used for this analysis, pp (pp + irrigation in Santiago del Estero) and maximum T were the variables that mostly determined the incidence of the disease. Mean T was the most important variable regarding severity. |

En los últimos años se vienen observando daños crecientes de una enfermedad viral que afecta la producción y la persistencia del cultivo de alfalfa en Argentina. El objetivo de este trabajo fue comparar la incidencia y severidad de la sintomatología de la enfermedad y explorar las relaciones de su dinámica con respecto a precipitaciones (pp) y temperaturas (T) ambientales en seis cultivares comerciales de alfalfa durante el período 2010-2014. Los cultivares CW1010, WL1058, Traful PV INTA, WL903, Monarca SP INTA y LPS8500 fueron evaluados en los campos experimentales de la Estación Experimental Agropecuaria (EEA) Manfredi del Instituto Nacional de Tecnología Agropecuaria (INTA) y de la EEA Santiago del Estero-INTA. En ambos ensayos se registraron incidencias medias entre 50% y 80%, con importante variabilidad interanual y diferencias entre cultivares. La severidad fue mayor para los cultivares evaluados en Santiago del Estero. Los cultivares WL903 y WL1058 presentaron menor severidad, mientras que LPS8500 y Monarca SP INTA presentaron los mayores valores. De las variables climáticas utilizadas para este análisis, la pp (pp + riego en Santiago del Estero) y la T máxima fueron las de mayor peso para explicar la incidencia de la enfermedad. Con respecto a la severidad, la variable que mayor explica su incremento es la T media.
