| 摘 要： | 选取数量性状有较大差异的6个近江牡蛎（Crassostrea hongkongensis）作为亲本，成功建赢了9个半同胞家系，并对各个家系的受精、孵化、成活和早期生长的情况进行比较。结果显示，各家系子代的受精率、9孵化率和成活率均受亲本成熟度的影响；各家系的早期生长中，家系CH1、CH4和CH7的生长率大于其他家系；近江牡蛎幼虫的早期生长阶段受母本效应影响明显。 |
| 关 键 词： | 近江牡蛎 家系选育 早期生长比较 母本效应 |

| Abstract: | We established 9 half-sibling families of Crassostrea hongkongensis using 6 parents with significant difference in body size, to compare the fertilization rate, hatching rate, survival and early growth among these families. The results show that the tertilization rate, hatching rate and survival are affected by the degree of parents＇ maturity. Besides, the growth rates of family CH1, CH4 and CH7 are greater than those of the others. Meanwhile, significant maternal effect is observed on early developmental stages of these families. |
| Keywords: | Crassostrea hongkongensis family breeding comparison of early growth maternal effect |
