For disease evaluation, 112 F2:3 families derived by self-pollinating F2 plants, 31 BC1-P1, and 31 BC1-P2 plants were used. In the F2:3 progeny test, a completely randomized block design was used. Two blocks were tested, and eight plants for each F2:3 family were replicated for each block. Plant management and inoculation in the greenhouse were performed following the same methods for the experiment of race identification with melons.
