dc.description.abstract | Inductions of hybrids and reciprocal hybrids between Oryzias dancena and O. javanicus (ODJ and OJD) were conducted and backcross hybrids between female O. dancena and male ODJ were also produced for biological and cytogenetic analysis. Embryonic development of ODJ and OJD were compared with those of their parents. Developmental time was fastest in O. dancena and ODJ, followed by O. javanicus and OJD. Oryzias dancena hatched 11 days (d) after fertilization, ODJ at 13 d, O. javanicus at 14 d and OJD at 15 d. The abnormality of external morphology rate in ODJ was 10.6%; however, OJD showed a high degree of abnormality, over 90%. The proportion of males was 90.0% and 31.3% for ODJ and OJD, respectively. Cytogenetic analysis was conducted to obtain basic information for genetic identification of O. dancena, O. javanicus and their hybrids. The karyotypes of all experimental groups showed 2n=48 chromosomes and the fundamental number (FN) was 48. The first pair carried secondary constrictions near the centromeric regions. Erythrocyte area and volume were 9.8 ± 0.5 μm2 and 18.2 ± 1.0 μm3, respectively, for O. dancena, 8.3 ± 0.5 μm2 and 15.8 ± 1.5 μm3 in O. javanicus, and 18.3 ± 0.5 μm2 and 15.7 ± 1.3 μm3 in ODJ. Erythrocyte area and volume in ODJ were similar to those of O. javanicus. In backcross hybrids between female O. dancena and male ODJ, all embryos failed to develop and died in the late gastrula stage. | - |
