Abstract :Eggplant insert ignore into journalissuearticles values(Solanum melongena L.); is widely consumed vegetables like potato and tomato. Worldwide, the eggplant is cultivated in all regions and Turkey is the fourth largest eggplant-producer. It is a rich source of minerals and as a low-calorie fruit. Eggplant plays a vital role having high phenolic content which enhance the radical absorbing capacity. Objective of this study was to evaluate the effect of tomato spotted wilt orthotospovirus insert ignore into journalissuearticles values(TSWV); on five different eggplant cultivars insert ignore into journalissuearticles values(Kemer, Aydın Siyahı, Halep Karası, Topan and Silindirik); under greenhouse conditions. Eggplant cultivars were mechanically inoculated with TSWV isolates and tested by DAS-ELISA method. According to DAS-ELISA and visible virus-like symptoms, all tested cultivars were susceptible to TSWV infection and showed typical tospo-like symptoms including concentric ringspot, necrosis, chlorotic ringspot, and necrotic ringspot. The highest infection rate was observed in Kemer insert ignore into journalissuearticles values(58%); followed by Topan insert ignore into journalissuearticles values(52%); whereas, the lowest infection rate was noticed in Silindirik insert ignore into journalissuearticles values(38%);. Infection of TSWV caused significant insert ignore into journalissuearticles values(p≤0.05); reduction in fruit number insert ignore into journalissuearticles values(32.99-59.34%);, fruit length insert ignore into journalissuearticles values(17.12-49.76%);, fruit diameter insert ignore into journalissuearticles values(12.44-38.30%);, fruit weight insert ignore into journalissuearticles values(31.31-67.70%);, flesh thickness insert ignore into journalissuearticles values(18.11-46.05%);, total soluble solid insert ignore into journalissuearticles values(16.83-40.69%);, fruit color, fruit firmness insert ignore into journalissuearticles values(4.88-29.25%); and yield insert ignore into journalissuearticles values(50.22-84.22%); in infected plants. According to the results obtained, the cultivar Silindirik performed better performance against TSWV among all the tested cultivars. Whereas the performance of the Kemer and Topan was poor making them more sensitive to TSWV. These results will help breeders for the development of TSWV resistant varieties by using these tolerant cultivars.
