Abstract
Yellow mosaic disease caused by tomato leaf curl New Delhi virus is very severe and causing 100 per cent yield loss under
epiphytotic conditions. Chemical control of this disease is neither economical nor eco-friendly and genetic resistance is an
efcient means for its management. Resistance to yellow mosaic disease in advanced inbred line IIHR-Sel-1 and IIHR-137
have been confrmed during screening experiment. A crossing programme was planned using Arka Prasan as susceptible and
IIHR-Sel-1 and IIHR-137 as resistant parents. We used the F1, F2, BC1 and BC2 generations derived from the two crosses
viz. Arka Prasan×IIHR-Sel-1 and Arka Prasan×IIHR 137 to study the inheritance of resistance to yellow mosaic disease.
Results indicated monogenic recessive resistance to yellow mosaic disease in the genetic background of both parents which
need to be confrmed through repeated experiments with large population size. These results are imperative for breeding
yellow mosaic disease resistant cultivars in Lufa species.
