Screening of tomato varieties/cultivars against Fusarium oxysporum f. sp. lycopersici causing wilt of tomato

Abstract:

Tomato (Solanum lycopersicum L.) cultivars were evaluated to identify the source of resistance against wilt caused by Fusarium oxysporum f. sp. lycopersici. The eleven varieties were screened for relative resistance or susceptibility to Fusarium oxysporum f. sp. lycopersici under cage house condition. Tomato eleven varieties namely, Pusa ruby, Tycon, Sulabh, Sarathi, Shakti, To-1057, NHT-1813, MAHY-302, Emrol, Arka samrat, KSP-1154 are observed of larger variation in respect of disease expression. Among the different varieties with incidence ranging from 10.03-85.00 percent mortality recorded. The variety of tomato Arka samrat (10.03 percent) showed highly resistant and Tycon (27.50 percent) showed moderately resistant while Emrold (85.00 percent) and Sarathi (75.02 percent) were highly susceptible reaction against FOL of tomato. In this screening no variety was immune.
