The invention relates to a production method for pepper hybrids. The production method comprises the following steps: (1) sowing seeds of pepper half-sterile line female parent; (2) sowing pepper stock and male parent seeds when the half-sterile line female parent grows for 1.5-2.5 months; (3) removing pollen plants after the half-sterile line female parent flowers; (4) grafting twigs and branches, taken as scions, of the female parent without pollen onto the stock; and (5) performing pollination when the scions and male parent of the grafted seedlings flower, thereby acquiring the pepper hybrids after fruit is ripened.
