Comparisons Between Bacterial Wilt Resistant and Susceptible Gynoecious Cucumber Lines and F1 Progeny

Four sets of nearly isogenic bacterial wilt [Erwinia tracheiphila (E.F. Smith)] Holland resistant and susceptible gynoecious cucumber (Cucumis sativus L.) lines, along with their companion segregating generations were evaluated under replicated field conditions for flowering date, fruit quality, fruit number, and length : diameter ratio (L:D). In addition to flowering earlier, susceptible lines were higher-yielding and had longer fruits than their resistant counterparts. Although differences in fruit quality were not significant, susceptible lines were preferred by a panel of seven judges. Compared to susceptible lines, hybrid progeny were later-flowering and in some instances lower-yielding.
