Breeding method of novel preserved szechuan pickle variety suitable for mechanical harvesting

The invention relates to the technical field of vegetable breeding, and particularly discloses a method for breeding a new variety of preserved szechuan pickle suitable for mechanical harvesting, which comprises the following steps of: performing hybrid seed production by taking a preserved szechuan pickle cytoplasm male sterile line 13-06A as a female parent and a plate-leaf type inbred line 13-09 as a male parent to breed a new variety of preserved szechuan pickle Yongzhou No.6; the novel preserved szechuan pickle variety bred by the invention is suitable for mechanical harvesting and has excellent processing characters; the height of the base part of the tumor stem to the ground is 2.9 cm, and the lodging rate of the rhizome is 2.3%; after harvesting by a harvester, the loss rate of the tuberous stems is 6%; the hybrid variety is the first hybrid variety suitable for mechanical harvesting in China, the distance between the base part of the tumor-shaped stem and the ground is more than 2 cm higher than that
