The objective of this study was to compare two methods of avocado graft development to determine levels of indirect resistance to Phytophthora cinnamomi. It was found that the etiolated graft method presented faster growth and greater uniformity in the lesions generated by the pathogen, which allowed for discrimination of resistance levels among genotypes. Additionally, the process of seed conditioning and production of West Indian avocado rootstocks in Colombia is described, as well as the vegetative propagation method of two avocado genotypes. A study on the development of Hass and Duke-7 avocado shoots using different methods is also presented, as well as another study on the development of the disease caused by the P. cinnamomi pathogen in avocado grafts. Finally, the potential use of avocado germplasm as rootstocks for soil stress conditions is mentioned, and other aspects related to avocado cultivation are discussed. [Extracted from the article]
