Abstract

The investigation was conducted at SKL Telangana State Horticultural University, Rajendranagar in Kharif, 2018 using 23 tomato genotypes. Screening with Ty-1 (P6-6) marker, only one genotype i.e. AVTO-1219 showed resistant band. Screening with Ty-2 marker, only 2 genotypes viz., AVTO-1219 and AVTO-9804 showed resistant bands. Screening with Ty-1 (SSR 47) marker, 3 genotypes i.e. AVTO-1219, AVTO-9803 and AVTO-9804 showed resistant bands. Using Fw-Z 1063 marker, 10 genotypes viz., EC-615055, EC-620428, AVTO-1219, EC-620378, EC-620389, EC-620394, EC-620422, EC-631369, EC-620503 and AVTO-9803 showed resistant bands. At molecular level, these ten genotypes showed resistant bands and these genotypes contain I-2 genes.

Genetic diversity gene specific primers fusarium wilt tomato yellow leaf curl virus and tomato spotted wilt virus.
