الملخص EN

Field surveys were conducted to assess the incidence of Tomato ringspot virus (ToRSV, genus Nepovirus, Family Comoviridae) infection in stone fruit trees in Jordan during 2000-2002.

A total of 2546 samples, collected from commercial orchards, a mother block, nurseries and a varietal collection were tested for ToRSV infection by DAS-ELISA.

Results showed that 16 % of the tested samples were infected with the virus.

The disease incidence percentages in apricot, almond, peach, nectarine, plum and cherry trees were 10, 14, 15, 19, 22 and 28 % of the tested trees, respectively.

The level of viral infection was highest in the commercial orchards (20 %) and lowest in samples obtained from nurseries (5 %).
