The influence of different environmental conditions on male sterility was investigated in interspecific cytoplasmic male‐sterile cottons. In Gossypium arboreum cytoplasm, the sterility scores in male‐sterile stocks of cotton showed positive correlations with wind velocity, pan evaporation, and heliometer in the period 2 to 3 weeks before anthesis while maximum and minimum temperatures showed negative correlations. The male‐sterile stocks with Gossypium anomalum cytoplasm had negative correlations with the temperature and heliometer during the same period. Multiple correlations showed interactions between the environmental conditions. Different locations were affected by different conditions.
