Abstract：In order to clarify the influence of meteorological factors on the cotton restoring ability of the restorer lines,four cytoplasmic male sterile lines were crossed with one restorer lines originating from Gossypium harknessii,and the pollen fertility of F1 was studied,the meteorological factors were detected.The relationship was analyzed between restoring ability of cotton restorer and meteorological factors by multiple comparisons,correlation analysis and path analysis method.Multiple comparison results showed that,pollen fertility restoring degree of different combinations was significantly affected by meteorological factors at different time.Correlation analysis results showed that the correlations between pollen fertility restoring degree and sunshine hours(r=0.523**),ground average temperature(r=0.457**) were extremely significant positive,and the correlations between pollen fertility restoring degree and average temperature (r=0.395*),maximum temperature(r=0.355*),minimum temperature(r=0.367*),evaporation(r=0.344*),maximum ground temperature(r=0.366*),lowest ground temperature(r=0.406*)were significant positive.Path analysis results showed that the influences of maximum temperature and relative humidity on pollen fertility restoring degree were larger and negative,and the influences of average temperature,minimum ground temperature and sunshine hours on pollen fertility restoring degree were positive,indicating that increasing the three factors could promote the recovery ability of combination of three-line hybrid cotton.
