Fig. 1: Phenotypic characterization and statistical analysis of less seed watermelon line “148 × JM” F1 hybrid, normal female parent line “148”, and male parent line “JM”.

A Fruit morphology and longitudinal sections of three watermelon lines. Bars=2 cm. B The seed number per fruit of the three watermelon lines. N = 10 represents ten fruits for each line. Values are the means + SD. The statistical data were analyzed with a one-tailed Student’s t test to evaluate significance. Double asterisks indicate significant differences with respect to the watermelon parent lines (t test at p < 0.01)
