High-efficiency pea cross breeding method

The invention discloses a high-efficiency pea cross breeding method. The high-efficiency pea cross breeding method comprises the following steps of: (1) performing castration, namely selecting a bud to bloom from a female parent plant, holding the torus lightly with the hand, clamping the position 3.5 to 4.5 cm away from the top of vexil and the connecting position of the vexil and the torus by using forceps, and clamping and pulling out petals, wherein the included angle of the forceps and the bud back line is 40 degrees; (2) performing pollination, namely selecting a male patent flower withpollen to be scattered or scattered just now, taking out pollen grains to place into a culture dish, clamping the pollen grains scattered just now by using the forceps, and coating the pollen on the tomentum of an exposed stigma of the female parent flower; (3) fastening a label; and (4) pruning. By the method, all the petals are pulled out at one step by the forceps, so the castration speed is high and the castration is
