Wheat crop is

Wheat crop is a self-pollinated crops.
The transfer of pollen from the anther of a flower to the stigma of the same flower or sometimes to that of a genetically identical flower is termed self-pollination. And plants that undergo this sort of pollination are termed self-pollinating crops.
e.g: beans, broccoli, cabbage, carrots, cauliflower, corn and onions.
wheat produces seed when pollen from anthers fertilizes the receptive ovary in the same flower of a single-parent plant.
