Abstract
Crosses were made between diploids and tetraploids of C5, a sister line of ‘Sweet Princess’ watermelon [Citrullus lanatus (Thunb.) Matsum. and Nakai] which was resistant to anthracnose (Glomerella cingulata var. orbiculare, S. F. Jenkins & Winstead races 1 and 3) and ‘Sugar Baby’ (SB) susceptible to anthracnose. There was no significant difference in anthracnose resistance among C5 (2x, 3x, 4x,), nor among SB (2x, 3x, 4x). The diploid hybrid SB(2x) × C5(2x) was similar in resistance to its tetraploid hybrid, SB(4x) × C5(4x). C5(2x) × SB(2x) was slightly less resistant than its reciprocal hybrid SB(2x) x C5(2x). The triploid seedless hybrid, C5(4x) × SB(2x) (ArArar), was significantly more resistant than its “reciprocal” hybrid, SB(4x) × C5(2x), (Ararar).Keywords
