Improvement of new tomato varieties resistant to Fusarium oxysporum f. Sp. Radicis lycopersici

Tomato is an important vegetable and production in World is more than 160 million tons of every year. Fusarium crown and root rot, caused by Fusarium oxysporum f. sp. radicis lycopersici (FORL), cause significant yield losses to range between 20 and 60% in glass house and field tomato crops. The objective of this study was to develop new tomato cultivar which is resistant to FORL. Plants were tested against fusarium crown and root rot in root using the dip inoculation method. Four weeks after inoculation, resistant and susceptible plants assessed for susceptibility. Tomato cultivars were also screened Frl gene for FORL with SCARFrl markers. Hybrids were evaluated for yield, color and shape. As a result, FÇ154, FÇ99 and FÇ131 hybrids were selected as a beef type, and FÇ85, FÇ140 and FÇ89 were selected as cherry and cocktail types. © 2020 International Society for Horticultural Science.
