Abstract Three molecular markers Ty1, Ty2 and Ty3 linked to ToLCV resistance were validated in fourteen ToLCV resistant entries a susceptible check Pusa Ruby. Among these, two advanced breeding lines IIHR-2822 and IIHR-2823 showed the presence of the all three genes TY1, Ty2 and Ty3 for ToLCV resistance, the wild accession Solanum habrochaites LA-1777 (IIHR-2101) showed the presence of two genes Ty2 and Ty3, Abhinava showed the presence of Ty1 gene and Hisar Anmol (H-24), Vyabhav, Arka Ananya, Lakshmi, NS-501 showed the presence of the only Ty2 gene. In varieties Nandhi and Sankranthi; hybrids Shakthiman and US-618 and the advanced breeding line IIHR-2611 (TV 55) Ty1, Ty2 and Ty3 resistant genes were absent hence the resistance in these lines may be due to different resistant gene.
