 ABSTRACT

The tomato (Solanum lycopersicum L.) is one of the most widely consumed vegetables in the world. Tomatoes are adversely affected by a multitude of infections caused by fungi, bacteria, viruses, nematodes, and abiotic factors. Early blight disease caused by Alternaria solani and Tomato leaf curl virus have been a serious problem in tomato growing areas, particularly in humid tropical, subtropical, and temperate regions of the world. 97 genotypes were screened for 2 diseases at 60 DAT. 31 showed high resistance, 32 genotypes were showed resistant, 17 showed moderately resistant no genotypes found highly resistant, 16 showed resistant reaction, 12 genotypes were found moderately resistant for the Early blight at 90 DAT. At 60 DAT, 38 genotypes showed highly resistance, 16 showed resistance reaction, 17 were moderately resistance. During 90 DAT, 17 genotypes showed highly resistance reaction, 27 were resistant, 13 were moderately resistant against leaf curl. The genotypes showed resistant reaction were TGP 60, TGP 27, TGP31, TGP77, TGP63 and TGP65 to early blight reaction. TGP96, TGP8, TGP36, TGP80, TGP88, TGP13 and TGP 21 genotypes were highly resistant reaction against leaf curl virus.

Key words: Incidence, Resistant, Susceptible, Severity.
