Title:
BREEDING METHOD FOR OBTAINING HETEROSIS FOR LINED SEAHORSE (HIPPOCAMPUS
ERECTUS)
Document Type and Number:
WIPO Patent Application WO/2017/004936
Kind Code:
A1
Abstract:
A breeding method for obtaining heterosis for a lined seahorse (Hippocampus
erectus) comprises the following steps: S1 selecting parents from lined seahorse groups having greatly different genetic backgrounds; S2 intensively nurturing the parents before birth; S3 pairing parents from geographically different lined seahorse groups for breeding according to a complete diallel cross; S4 attentively caring for pregnant seahorses; S5 respectively collecting all hatched larval fishes (filial generations) of each breeding pair within one week; S6 nurturing the filial generations; and S7 comparing survival rates and growth rates of the filial generations. By hybridizing lined seahorses from geographically different groups to obtain hybrids, and effectively using the heterosis, compared with non-hybridized second generations, the survival rates and growth rates of the filial generations are increased significantly, thereby increasing genetic diversity of lined seahorses and facilitating selection of advantageous breeds thereof.
