三倍体贝类因其具有生长快、个体大、肉质佳和成活率高等优良的经济性状而在水产养殖业中具有重要的应用价值[1]。获得100%三倍体贝类的最佳途径是通过四倍体贝类与二倍体贝类杂交来获得。目前已经发展出多种诱导四倍体的方法,包括抑制受精卵第一极体的释放、抑制受精卵的卵裂?
Triploid shellfish has an important application value in aquaculture because of its excellent economic traits such as fast growing, large individual, good fleshy quality and high survival rate. The best way to get 100% triploid shellfish is through tetraploid shellfish and diploid shellfish. A variety of methods have been developed to induce tetraploids, including inhibiting the release of the first polar body of the fertilized egg and inhibiting the cleavage of the fertilized egg.
