Abstract: The relationships between seed yield and plant growing conditions of 6 populations that were grown in typical habitats were studied in Junggar basin. Correlation analysis indicated that seed yield (M) had high and positive correlations with crown (C), basal diameter (D) and height (H). Path coefficient analysis showed that crown had the maximal and positive direct effect on seed yield, followed by height and diameter. Finally, Established seed yield prediction model is M=178.572+3.470×10-5×CH-1.106×H-0.007×C (R=0.830，p<0.01)
