Reproduction uniparentales et polyploïdie induite chez la truite arc-en-ciel (Oncorhynchus mykiss) et chez les Bivalves Crassostrea gigas, Ruditapes philippinarum et Chlamys varia.

Abstract : Methods of gynogenesis, androgenesis and polyploidy induction were developed with the aim of genetic improvement in the rainbow trout, the Pacific oyster, the Manila clam and black scallop. In the trout, haploid and diploid androgenesis were induced by pressure shocks, and homozygous gynogenetic lines were produced by a heat shock (and with UV-irradiated sperm). In the mollusks, triploidy was induced egg treatment with cytochalasin B (clam and scallop), tetraploidy was attempted using a pressure shock (oyster) and cytochalasin B (clam). Gynogenesis was induced with UV-irradiated sperm. Subsequent treatments of eggs with cytochalasin B resulted in diploid and tetraploid eggs.
