[0023] The croissant pepper No. 21 (fruit length is 11.79 cm, fruit shoulder width is 2.3 cm, flesh thickness is 2.09 mm, single fruit weight is 13.27 g, has a spicy taste) is used as the reincarnation male parent, and the cytoplasmic male parent of the lantern-shaped sweet pepper is used. The breeding line LANES is the sterile source. As the female parent, after 6 generations of hybridization, backcrossing, identification and selection, a new capsicum capsicum cytoplasmic male sterile line 21A (fruit length 11.77 cm, shoulder width 2.56 cm, flesh thickness 1.91 mm, single fruit weight 13.2 grams, with a spicy taste). See Table 1 for the breeding process and fruit traits of the CMS line 21A of croissant pepper.
