 In: Experimental AgricultureSummary: Se investigo la relacion entre los potenciales de la fuente y las capacidades receptor en 4 var. de yuca (Arubielupupa, Isunikankiyan, TMS 30211 y 58308) con diferentes caracteristicas, mediante injertos reciprocos (16 combinaciones posibles). Hubo notorias diferencias en las capacidades receptor (efectos prom. del patron) y los potenciales de la fuente (efectos prom. del acodo) de la var. TMS 30211 presento los mayores efectos prom. del patron y del acodo, lo que indica que esta var. poseia el mayor potencial de fuente y la mayor capacidad receptor, ambos igualmente eficientes para la produccion de un alto rendimiento de raices de almacenamiento. Las var. locales nigerianas no mejoradas, Isunikankiyan y Arubielupupa, presentaron escasos potenciales de fuente y capacidades receptor, mientras que la var. 58308 presento valores prom. en los 2 parametros. Cuando cualquier var. servia de patron y el acodo era TMS 30211, el injerto correspondiente producia la mayor cantidad total de MS, seguido por 58308 como acodo. (RA-CIAT)Summary: The relationship between source potentials and sink capacities of 4 cassava var. (Arubielupupa, Isunikankiyan, TMS 30211, and 58308) with different characteristics was investigated by means of reciprocal grafts (16 possible combinations). There were marked differences in the sink capacities (av. stock effects) and source potentials (av. scion effects) of the var. TMS 30211 had the highest mean stock and scion effects, indicating that the var. had the highest source potential and sink capacity, both equally efficient in producing high storage root yield. Local Nigerian unimproved var. Isunikankiyan and Arubielupupa demonstrated poor source potentials and sink capacities, while var. 58308 showed av. values in both. Whenever a particular var. was the stock, the graft in which TMS 30211 was the scion produced the highest total plant DM followed by 58308 as scion. (AS)
