) were produced in this study. The results showed phenomenon of hybrid incompatibility such as low larval floating rate and high deformity rate. Thirty microsatellite primers were used for genetic analysis on relationship between F₁ hybrids and their parents. The results are as follows: 1) Among the 30 microsatellite primers, twenty-five pairs showed specific bands on both parents, and two pairs showed specific bands only on . 2) 24 bands of microsatellite locus came from parents and only one . The inherited character of 21 locus completely follows the Mendelian rule indicating that the hybridization between the parents are gamogenesis and most genetic material come from both of the parents. 3) Four loci doubled maternal bands or no paternal specific bands on some F₁ hybrids. This may be caused by abnormality in process of pairing or separation for some chromosomes, which may result in 1 hybrids and were 0.673 5 and 0.395 3 respectively, and the was 0.729 8 and 0.315 0 respectively. The results showed F₁ hybrids had closer relationship with It was also supported by UPGMA clustering.
