| 摘 要： | 本文介绍了以太平洋牡蛎、近江牡蛎、褶牡蛎为亲本的多种组合杂交试验。试验共分为:近?×太?,太?×近?,褶?×太?,太?×褶?四个试验组进行;另外还有三种牡蛎的三个自交组作为对照。试验结果表明,在适宜的环境条件下几种牡蛎的正反交均可受精。其中褶?×长?的受精率较高,而长×近的正反交的受精率均较低。杂交子:代的D型幼虫的大小性状一般表现为母本特征,而且其大小变异范围比亲本自交大。此外,文中对各组合的幼体发育作了比较,并对环境因子的影响进行了探讨。

| Abstract: | The ,Tananese oyster, Qstrer ,ggrcs is famous for its high production and fastgrowth and tb.e two native oysters, QsGrerx rirzatrrs and Ostrea pLicrtuIa, are welludapted to their Iacal environment. Cross breeding of gas with D. -iudrcris axedQ, pdicatu.b were attempted. paper deals with. tba probability of their interspecific hybridization, thesurvival and growth of the brid Iarvaa. The results of the experiment are asfollows 1 .The process of crass-breeding is easy to operate. The peroentage of fertilixartion in C. ggas×O. Pt2catuta is higher than in C, gigas×O. -iarctaras. 2. There is no any apparent difference in the time of development from eggs tothe straight-hinge larvae, but in the sedentary stages hybrids larvae grew faster thanthe native stocks. 3 .The size of hybrid straight-hinge Larvae are mainly influenced by maternalinheritance. . The range of variation in hybrid straight-hinge larvae is wider than that oftheir parents. 5. About 40,001) hybrid spats are reared in tanks and ready for further studies, |
