Abstract

ROCHA, Kelly Cristina et al. Yield losses caused by Tomato severe rugose virus (ToSRV) in pepper cultivars. Summa phytopathol. [online]. 2012, vol.38, n.1, pp. 87-89. ISSN 0100-5405.  http://dx.doi.org/10.1590/S0100-54052012000100015.

Tomato severe rugose virus (ToSRV) is the predominant species of begomovirus affecting pepper crops in São Paulo State, Brazil. Its occurrence is relatively recent for the culture thus, there is no information on yield losses caused by this virus on sweet pepper. The aims of this study were to evaluate yield and fruit fquality of three pepper cultivars (Magda, Amanda and Rubia R) infected with ToSRV. There was marked reduction in the number of fruits and in the growth of plants; however, ToSRV did not significantly influence the average weight, diameter and the length of fruits. The results obtained so far lead to the conclusion that ToSRV causes damage in peppers and it is necessary the development of resistant cultivars to ToSRV.
