The inheritance of resistance to chickpea (Cicer arietinum L.) wilt caused by Fusarium oxysporum f. sp. ciceri race 1 (Hyderabad) was studied in a set of diallel crosses among five resistant and two susceptible cultivars at Hyderabad. Studies of F₁, F₂, and F₃ generations of the three crosses involving the resistant parents CPS-1 and WR-315, and the susceptible parent C-104, indicated that resistance was conferred by a single recessive allele at the same locus in the two resistant parents. The resistance was successfully transferred from WR-315, CPS-1, and other resistant cultivars to a wide range of genetic backgrounds by hybridization and pedigree and bulk selection.
