Abstract:
After 100-grain weight, 100-grain volume and weight/volume measured, twenty-two soybean varieties were tested in a field to clear and definite the relations between characters of soybean seed, seedling characters and yield characters of soybean. Their seedling characters and yield characters were measured, and the correlative coefficients between characters of seed, seedling characters and yield characters were calculated and analyzed. Significant negative correlations between 100-grain weight and emergence rate and between 100-grain volume and emergence rate were found. However, 100-grain weight and 100-grain volume had much significant positive correlations with chlorophyll content and stem diameter of seedling， and with 100-grain weight and yield per plant of descendants. The soybean seedlings with higher content of chlorophyll tended to have higher 100-grain weight and yield per plant. The dry matter weight of root and stem of soybean seedling influenced yield per plant markedly. Therefore, selecting and using big grain seed of soybean can cultivated strong seedlings with higher content of chlorophyll and can gain higher yield.
