摘要

摘要: 于2007年10月，以F1代海洋红（R）和斑马蛤（Z）为材料，开展了2个壳色菲律宾蛤仔（Ruditapes phlippinarum）品系的群体杂交。试验由RR（R♀R♂）、ZZ（Z♀Z♂）、RZ（R♀Z♂）和ZR（Z♀R♂）组成。结果表明，2个壳色品系亲贝壳长、重量和产卵量差异显著（P0.05）。各试验组卵径、受精率和D形幼虫大小无显著差异（P＞0.05），但杂交组孵化率显著高于相应对照组（P0.05）。浮游期间幼虫未表现出明显的生长优势，但表现出一定的存活优势。RZ和ZR的生长优势平均值分别为（1.630.81）%和（2.580.67）%；生长速度分别为（8.640.32）和（8.670.31）md-1，显著高于相应对照组（P0.05）；存活优势分别为(10.301.92)%和(16.301.04)%。室内培育期间稚贝表现出明显的生长、存活优势。RZ和ZR的生长优势平均值分别为(11.252.98)%和(20.312.10)%；生长速度分别为（9.881.45）和（10.791.32）md-1，显著高于相应对照组（P0.05），存活优势分别为(40.859.90)%和(57.0811.98)%。

Abstract: The population hybridization was conducted by using clams Ruditapes plippinarum of two shell color strains ocean red(R), zebra(Z) strains in October of 2007. The experiments was consisted of RR (R♀R♂), ZZ (Z♀Z♂), RZ(R♀Z♂) and ZR (Z♀R♂) groups. Results showed that difference of shell length, weight and fecundity of parents were significant between two shell color strains (P＜0.05). There were no difference on egg-diameters, fertilization rates and sizes of D larvae among each experimental groups (P＞0.05). The hatching rates in hybrid groups were higher than in control groups (P＜0.05). At the planktonic stage, survival heterosis was obvious instead of growth heterosis for larvae tested. Survival heterosis were (10.301.92)% and (16.301.04)%, respectively for RZ and ZR, and growth heterosis for RZ, ZR were (1.630.81)% and (2.580.67)%. Growth rates for RZ, ZR were (8.640.32) and (8.670.31) md-1, respectively (P＜0.05). At indoor rearing stage, obvious growth and survival heterosis were found. The growth heterosis of RZ, ZR were (11.252.98)% and (20.312.10)%, the growth rates were (9.881.45) and (10.791.32) md-1, and the survival heterosis were (40.859.90)% and (57.0811.98)%, respectively. There was no significant difference of survival heterosis between RR, and ZZ (P0.05).
