| 摘 要： | 从杂种优势的角度对皱纹盘鲍♀与盘鲍♂杂交子一代的经济性状进行分析。结果表明,4月龄杂交鲍子一代(F1)活体重比皱纹盘鲍增加36.87%,软体部干重增加33.21%,总干重增加29.20%,其它性状也显著优于皱纹盘鲍。杂交鲍F1的壳长、壳宽、活体重、软体部干重和总干重等主要性状的变异系数为12.94%~44.51%,其中软体部干重的变异系数最大,壳长的变异系数最小;且杂交鲍各性状的变异系数均大于皱纹盘鲍。杂交鲍子一代的变异有助于定向选择,提高杂交育种的效果。

| Abstract: | F_1 hybrid abalones between 6Haliotis discus hannai Haliotis discus indicated that F1 hybrid had 36.87 % more live weight, 33.21 %more dry soft-body weight , and 29.20 % more total dry weight than Haliotis discus hannai at four month age. There were variation coefficients of 12.94 % 44.51 % in shell length, shell width, live weight, dry soft-body weight and total dry weight of F1 hybrid, in which the variation coefficient of dry soft-body weight was the maximal, the variation coefficient of shell length was the minimal. The variations of F_1 hybrid redound to directional selection, and the F_1 hybrids have advance effect on crossbreeding. |
