Controlled pollinations were made in the summer of 1989 between different watermelon lines containing the single recessive genes male-sterile (ms) and glabrous-male sterile (gms). F₁ plants grown in the greenhouse in winter of 1989-90 revealed no segregation for sterility in genotypes [(ms ms) x (Gms gms)] and [(gms gms) x (Ms ms)]. These data suggest that ms and gms are non-allelic.
