| Sumario: | The raspberry (Rubus idaeus) is one of the most important fruit for production in
the Maule Region, Chile. Raspberries are affected by the tomato ringspot virus (ToRSV),
which causes decreased yield and deformed fruit. The objective of this work is to study
ToRSV spread in different raspberry varieties in the Maule Region, Chile. The virus was
detected using the ELISA test and RT-PCR in the Heritage, Meeker, Chilliwack, Amity and
Coho varieties. Bayesian analysis determined the relationship between the percentage
of ToRSV incidence in the cultivated varieties and the locations in the different provinces
of the Maule Region. It was observed that the Linares province showed the highest levels
of the virus in the different varieties: Amity (70%), Meeker (39%) and Heritage (26%),
compared to other provinces in the region. These results suggest a high spread of ToRSV
through the Maule Region. Nei distance analysis suggests that 14 of the virus isolates
coming from the Talca and Linares Provinces would show differences with the ToRSV
accessions deposited in the global gene bank (NCBI).
