An experiment was conducted to study the genetics and nature of gene action of
resistance to watermelon bud necrosis orthotospovirus (WBNV) in watermelon. The
experimental materials comprised of two resistant (BIL‐53 and IIHR‐19) and one susceptible
(IIHR‐140) parents. Each of the resistant parents was crossed with the susceptible
parent to develop six generations (P1, P2, F1, F2, BC1 and BC2) to study
genetics. The results of segregation in F2 and backcross progenies suggested that
resistance is governed by a major dominant gene along with other background
minor genes in both the crosses. BIL‐53 was found to possess higher degree of
resistance with simple inheritance and hence may be of interest to breeders. Simple
selection can be effective for improving the trait in the cross BIL‐53 × IIHR‐140 as
additive gene action is prevalent.
