Abstract: 

A study was conducted at Al-Muturkiah village in Lattakia Governorate during the 2019/2020 growing season in the autumnal season and the experiment was repeated in the spring season to investigate the effect of Cucumber mosaic virus (CMV) infection on the area leaf, relative water content (RWC%) and productivity of four pepper hybrids (Taline F1, Amani F1, Harek F1 and Marvilo F1) at three periods post viral inoculation (15, 30 and 45 days). The experiment was carried out by using complete randomized block design with 8 treatments and 4 replicates per treatment. The results showed that the viral infection affected the area leaf, Relative water content and productivity on 15 days after virus inoculation. The highest effect of the viral infection was on 30 days after virus inoculation, where the values of area leaf, Relative water content (RWC%) and productivity of the infected pepper hybrids significantly decreased compared to control plants. However, 45 days after virus inoculation, the effect of the viral infection decreased with plant age.
