The presence of Peach latent mosaic viroid (PLMVd) was monitored during 2 years in peach orchards located in the North of Tunisia. PLMVd population was surveyed using a specific RT-PCR test adapted to crude sap extract. During the first year (2004), 228 samples were randomly selected in 22 peach orchards (eight cultivars) and tested for the presence of PLMVd. Results showed that PLMVd is highly and equally present in four regions of the North of Tunisia. Analyses of some key factors in relation to PLMVd incidence revealed that the tree age did not influence the infection rate. The eight studied cultivars were clustered in three groups according to their PLMVd incidence. Furthermore, the early and season cultivars were statistically more infected than the late cultivars. Prospections in May and October 2005 were performed in four selected orchards. Each two orchards contained Early May Crest (early cultivar) and Carnival (late cultivar) cultivars, respectively. The difference in PLMVd incidence observed in 2004 was confirmed. Furthermore, no correlation between the tree physiological state and the viroid detection was observed. Further investigations on the origin of the differences in PLMVd incidence between Early May Crest and Carnival cultivars would be of interest.
