Efficient broad bean hybrid breeding method

The invention discloses an efficient broad bean hybrid breeding method which comprises the steps of: 1, castrating: selecting a hybrid flower, clamping the top end of vexil and a connecting part of the vexil and flower base by using a nipper from one semicircular arc side of the vexil, and slightly clamping and completely extracting petals, wherein an included angle of the nipper and the flower back line is 30 DEG; 2, pollinating: pollinating in the same day or on the next day at 12-16 o'clock, selecting a male parent flower dispersing pollen or just dispersing pollen, clamping pollen particles subjected to just pollen dispersing, and coating the pollen particles on an exposed stigma of the female parent flower; 3, sleeving; and 4, pruning. The petals are clamped and completely pulled out by using the nipper, hybridization castration speed is high, the stigma is not damaged and is exposed so as to be convenient for pollinating; after the castration is finished, the female parent flower has no petals and anthe
