Variation in three quantitative traits (wing length, rate of development, and productivity) was assessed in natural populations of Drosophila melanogaster of Eurasia. Wing length was estimated in 16 populations of Eastern Europe, Caucasus, and Central Asia. It was shown to decrease in clinal fashion from northwest to southeast and was negatively correlated with temperature. No difference in developmental rate among three east European and three Central Asian populations was detected. Productivity was significantly higher in populations of eastern Europe as compared to those of Central Asia. Selective mechanisms of maintenance of clinal variation in natural Drosophila populations are discussed.
在欧亚大陆的黑腹果蝇自然种群中评估了三个数量性状（翅长、发育速率和生产力）的变异情况。在东欧、高加索和中亚的16个种群中估计了翅长。结果表明，翅长从西北向东南呈渐变趋势下降，且与温度呈负相关。未检测到三个东欧种群和三个中亚种群之间发育速率的差异。与中亚种群相比，东欧种群的生产力显著更高。本文讨论了自然果蝇种群中渐变变异维持的选择机制。
