Bay scallop southern subspecies x peruvian scallop hybrid three-line breeding system and method
The current invent relates to the construction and application of a three-line breeding system in the bay scallop southern subspecies x Peruvian scallop hybrids. The said three-line consists of a male sterile line, a maintainer line and a restorer line. A combination of male sterile line and maintainer line is obtained by continuously backcrossing the male sterile individuals selected from F1 inter-specific hybrid families with sperm of the selfing family of the sperm-providing Peruvian scallops until the progenies are all male sterile. The restorer line is obtained by continuously backcrossing selected individuals from the male sterile line with sperm of the selfing family of a Peruvian scallop until the progenies are all hermaphroditic and exhibit excellent production traits. Commercial male sterile brood stocks are produced by backcrossing the male sterile line with the maintainer line and commercial hybrid spats are produced by backcrossing the male sterile line and the restorer line.
