A detailed description of the bacterial wilt drench method is given in Hai et al. (2008). Inoculations were conducted with virulent R. solanacearum strain Pss4 from Taiwan. Pss4 is classified as Phylotype 1 (Asia), race 1, and biovar 3 (Hai et al., 2008). For inoculums preparation, stored cultures were streaked on tetrazolium chloride medium. Several fluidal colonies were transferred to plates containing 523 media for multiplication at 30 C for 24 h. Bacterial cells were harvested, suspended in water, and adjusted to OD600 = 0.3, (about 108 ◦CFU/mL). Four-week-old seedlings grown in 2-in. pots, approximately at the five-leaf stage, were inoculated without wounding the roots by pouring 20 mL of 1 × 10 8 inoculumon the soil surface at the base of each plant. Checks included L390 (susceptible) and H7996 (homozygous for Bwr-12 and Bwr- 6). Plots included 20 plants and were arranged in a RCBD with three replications. Plants in each plot were evaluated for wilting at weekly intervals for four weeks beginning one week after inoculation. Wilted plants died, so plants were scored as healthy or wilted and the percentage of wilted plants per plot was determined after the last evaluation.
