Effect of the temperature and the culture medium on the productivity of two generations of dihybrid crosses in Drosophila melanogaster

Abstract

In the present study we analize the productivity of the dihybrid cross +//+ e//e x vg//vg +//+ and its reciprocal, carried on up to the second generation under different environmental conditions: two culture media (maize and banana) and two temperatures (23 and 26ºC). The differences were shown to be statistically significantfor the temperature in the first generation, the culture medium and the parental line in the second generation. At a general level, the significant factors were the temperature and the culture medium. Perhaps the genotipic effects caused by the parental line are balanced and masked, when considered at this level. The temperature of 26ºC and the culture media of maize showed always the best productivity.
