Abstract
A tetraploid watermelon inbred 90-4194 is disclosed. The invention relates to the seeds and plants of tetraploid watermelon inbred 90-4194, the methods of propagating the tetraploid inbred 90-4194 through seeds and tissue culture. The invention also relates to methods of producing the triploid seedless watermelon seeds and plants by crossing inbred 90-4194 with diploid watermelon inbreds, and to the triploid plants produced therefrom. The invention further relates to the methods of developing new tetraploid lines by using tetraploid inbred 90-4194 as breeding material, and to tetraploid watermelon seeds and plants produced therefrom.
Claims18

- a) planting the seed of said female parent tetraploid watermelon 90-4194 and seed of said male parent watermelon plant in a field in a pattern of 2 rows female parent to 1 row male parent;
- b) pruning the plants of said female parent tetraploid watermelon 90-4194 to approximately 2-3 branches per plant;
- c) emasculating substantially all the male flowers and male flower buds on the plants of said tetraploid female parent 90-4194;
- d) allowing pollination of the female flowers of said female parent 90-4194 with the pollen of said male parent;
- e) marking the female flowers pollinated during the emasculating period;
- and
- f) harvesting the seed from the marked fruit of the tetraploid female parent plants.
