Abstract:
The aim of this study was to evaluate the effect of Tomato yellow leaf curl virus (TYLCV) infection on some growth parameters of several Capsicum hybrids grown under protected cultivation conditions along the Syrian coast. Four Capsicum hybrids were used in the study: 2 spicy (Lahab and Sirad) and 2 non-spicy (Nevada and Dallas) cultivars. The study was carried out during the growing 2020-2021 season in a plastic house at the Scientific Agricultural Research Center in Lattakia, where the complete random design was followed, with 8 treatments and three replications, with 5 plants per replication. Statistical analysis showed that the sweet hybrids (Nevada and Dallas) were more sensitive to infection by the virus compared with hot hybrids (Lahab and Sirad). The reduction in foliage fresh weight of the hybrids Nevada, Dallas, Cirad and Lahab was 17.97, 54.99, 5.36, 35.00 %, respectively, and reduction in root fresh weight of infected plants of 69.01, 68.65, 26.71, 61.87 %, respectively. TYLCV virus infection also contributed to a decline in the quality and quantity of fruits, as the highest rate of fruit loss of 70.21% was recorded for the Dallas hybrid, and the lowest 36.74% for the Nevada hybrid.
