ABSTRACT
Leaf curl disease of tomato caused by tomato leaf curl virus (ToLCV), a gemini virus, is transmitted by whitefly, Bermisia tabaci G. Thirty five tomato genotypes including wild accessions were screened for its resistance/ susceptible reaction against tomato leaf curl disease in field condition during summer cropping season 2015. Among the screened thirty five genotypes, seven genotypes Vaibhav, EC541109 (Solanum pimpinellifolium L.), EC168283 (Solanum pimpinellifolium L.), IIHR2372 (Solanum lycopersicum L.), IIHR1970 (Solanum peruvianum L.), IIHR2200 (Solanum lycopersicum L.) and LA2805 (Solanum lycopersicum var. cerasiforme L.) showed high resistance against ToLCV without producing any symptoms of leaf curl disease. One genotype viz., EC165751 showed resistant reaction and two genotypes viz., Nandi and EC620545 showed moderately resistant reaction to ToLCV, Twelve genotypes showed moderately susceptible reaction, seven genotypes showed susceptible reaction and six genotypes were identified as highly susceptible to ToLCV. Solanum pimpinellifolium L. species is compatible with the cultivated Solanum lycopersicum L. So it can be used successfully as the source of resistance in breeding program. Identified genotypes can be screened for resistance genes using markers and can be used in the molecular breeding programmes for resistance to leaf curl disease in tomato.
Key words: Tomato; ToLCV, Wild species, Resistance.
