Abstract:
Resistant heterozygotes (Ty-2/ty-2)，resistant homozygotes (Ty-2/Ty-2) and susceptible homozygotes (ty-2/ty-2) were used as experimental materials.Based on the published RFLP markers tightly linked to Ty-2，three pairs of specific primers were designed for PCR amplification.As a result，two steady-going and effective SCAR markers，T0302-1 and T0302-2，were found.The results showed that T0302-1 and T0302-2 were co-dominant SCAR markers，which could be used in marker assistant selection for tomato disease resistance breeding.This paper was aimed to obtain molecular markers tightly linked to Ty-2 gene resistant to tomato yellow leaf curl virus and afford technical supports for tomato disease resistance breeding.
