✦ Synopsis

Inheritance of resistance to tomato leaf curl virus (TLCV) was studied in the progenies derived from interspecific crosses between TLCV resistant Lycopersicon hirsutum f. glubratum line B 6013 and five susceptible cultivars (HS 101, HS 102, HS 110, Pusa Ruby and Punjab Chhuhara) of L. esculentum. Pt, Pz, Ft, Fz, Bt and B2 progenies of the live crosses were artificially inoculated with local strains of TLCV by means of the vector whitefly, Bemisia tabaci (GENN.), and the disease reaction was studied in all the crosses. Reaction of parents, Fi, Fz and backcrosses suggests fhat resistance derived from L. hirsutum f. glubratum B 6013 is based on two epistatic genes, one from the wild parent and one from the cultivated one, resulting in a 13 : 3 segragation in the Fz.
