DIAZ-GONZALEZ, FERNANDO et al. Evaluation of Two Culture Media and Heritability of Productivity and Development Time for Three Mutants of Drosophila melanogaster (Drosophilidae). Acta biol.Colomb. [online]. 2008, vol.13, n.1, pp.161-174. ISSN 0120-548X.

With the objective of investigating the effect of the culture media in the productivity and development time egg-adult of Drosophila melanogaster in +/+ and three mutants (CyLv, vg, w), two culture media: banana and orange, were evaluated. An experimental design with two factors: culture media and kind of flies-stock, were tested, for a total of eight treatments with five replicas each one. The productivity and development time depend on culture media and kind of flies-stock, and the biggest productivity was in the orange culture media. The +/+ presented the biggest productivity and lowest development time in both culture media (α=0.05). The genetic analysis showed a low heritability and the phenotypic variation was due, in a mayor part, to the component of the interaction genotype-environment that explains the difference in the patron of productivity and development time between culture media.

Keywords : Drosophila melanogaster; heritability; development time; productivity; mutants.
