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.
