Abstract

Inheritance of the resistance to Fusarium oxysporum melongenae in eggplant was investigated. LS1934 and LS2436, two resistant genotypes from Malaysia, were reciprocally crossed with the susceptible local inbred line NSB99 and seeds of F1, F2 and BC, generations were obtained. Resistance tests were carried out by artificial inoculations in segregating populations, using a highly virulent isolate (AF) originated from Turkey. The root-dip inoculation method was used as the resistance test. Results showed that the inheritance of resistance in both LS1934 and LS2436 are controlled by a single dominant gene. Goodness-of-fit test (c(2) analysis) was performed for the segregation. The segregations fitted a '3 resistant and 1 susceptible' ratio in chi(2) populations, and '1 resistant and 1 susceptible' ratio in BC(1) populations. Maternal effect was not found in the inheritance of the resistance.
