VARELA M., Alexander  and  ALFARO-MORA., Ramsés. Main strategies to obtain polyploids in bivalve molluscs. rev. colombiana cienc. anim. Recia [online]. 2021, vol.13, n.1, pp.89-101.  Epub Jan 24, 2023. ISSN 2027-4297.  https://doi.org/10.24188/recia.v12.n2.2020.844.

Global production of bivalve has grown greatly due mainly to the increase in cultivated species, the expansion of geographical production regions and the improvement of production techniques. The lines of cultivated organisms have undergone rigorous studies on their biological systems, their potential and genetic improvement. Among the strategies used, the use of polyploids has allowed great zootechnical advances, while having represented great technical challenges. This work describes the main techniques of induction to polyploidies, as well as their limiters. It describes the physical and chemical methods of induction and their main characteristics and results obtained.

Keywords : Bivalve; chromosome; improvement; induction; mechanisms; polyploid.
