Transfer of tomato leaf curl virus (ToLCV) resistance from Solatium pimpinellifolium to Solatium lycopersicum L.

摘要

The transfer of tomato leaf curl virus (ToLCV) gene was studied in the progenies derived from the interspecific crosses between ToLCV resistant Solanum pimpinellifolium to Solanum lycopersicum L., related two susceptible cultivar DVRT-2 and PBC and one resistant wild line EC-520074. The P_1, P_2, F_1, F_2, BC_1, and BC_2, progenies of the two crosses were natural and artificial inoculation with local strains of ToLCV by means of parents. The P_1, P_2, F_1, F_2, BC_1, and BC_2 related two resistant parent EC-520074 based on two epistatic gene effect one is the wild parent and other from the cultivated, resulting from the ratio of 13:3 segregation in F2 and 1:1 in BCj, respectively.
