Inﬂuence of a viral complex on yield and chlorophyl content of two varieties of sweet potato.

Virus diseases are the main constraint of sweet potato yield, the ﬁfth largest food crop. In Argentina, “yellow curling” (EA), a viral complex with seven agents involved, causes notable losses in all the growing regions. The inﬂuence of EA on yield components of Arapey INIA and Beauregard cultivars...

Inﬂuencia de un complejo viral en rendimiento y contenido de cloroﬁla de dos variedades de batata Buxmann, E. Vilanova Perez, A. Suasnabar, R. Luque, A. Araujo Vieira de Souza, J. C. Di Feo, L. Virus diseases are the main constraint of sweet potato yield, the ﬁfth largest food crop. In Argentina, “yellow curling” (EA), a viral complex with seven agents involved, causes notable losses in all the growing regions. The inﬂuence of EA on yield components of Arapey INIA and Beauregard cultivars was analyzed by comparative trials that combined two health conditions and two genotypes. Healthy plants were obtained by thermotherapy and in vitro culture of meristems and the diseased ones, by grafting with EA. There were signiﬁ cant differences between health conditions, in chlorophyll content and losses in yield characters near to 90%. Weight and number of commercial roots were the most affected by EA in both cultivars. This work corroborates the relevance of EA on sweet potato production. Virus free plants and good management practices increase greatly the yields.   Las virosis son la principal limitante del rendimiento de batata, quinto cultivo alimenticio del mundo. En Argentina, el “encrespamiento amarillo” (EA), complejo viral con siete agentes involucra-dos, causa notables pérdidas en los genotipos de toda región productiva. Se analizó la inﬂuencia del EA en componentes de rendimiento de los cvs Arapey INIA y Beauregard. mediante ensayos comparativos que combinaron dos condiciones sanitarias (sana vs enferma) y dos genotipos. Las plantas sanas se obtuvieron por termoterapia y cultivo in vitro de meristemas, y las enfermas, injertando púas con EA. Hubo diferencias signiﬁcativas entre condiciones sanitarias, para contenido de cloroﬁlas y mermas de caracteres de rendimiento cercanas al 90%, donde peso y número de raíces comerciales fueron los más afectados por EA en ambas variedades. Se corrobora la relevancia del EA como limitante del cultivo y del empleo de materiales saneados junto a buenas prácticas de manejo para alcanzar rendimientos potenciales.
