AbstractSupermale (YY male) P. fulvidraco was generated by combining the hormone sex reversal with gynogenetic technique. Comparing with the sex reversal and progeny testing selection technique,the combination of techniques described in present paper reduced the time comsumption of selective breeding two generations and increased supermale yield. YY male genotypes proved through progeny testing to be as viable and fertile as normal XY male and sired a mean progeny sex ratio of 90.3% male, ranging from 75.9% to 100% .294 meiogynogens produced from 29 normal females were predominately female, and merely 11 males and 12 supermales sired female progenies at the frequencies between 0 and 24.1% From these results mentioned above, the sex determination system in P. fulvidraco was presumed to be female homogamety, but the influences of autosomal sex modifying genes were more obviously.The feasibility and application prospect for commercial mass production all - male P. fulvidraco were discussed briefly.
