Abstract:
In order to evaluate the heterosis of domestic and foreign soybean hybrid,the thesis analyzed the heterosis of twenty hybrid combinations with 9 soybean germplasm，4 from China and 5 from abroad，as parents.The results showed that some of the morphological，yield and quality traits had higher heterosis，but there were obvious differences among different combinations.Seed weight per plant is heavier than average of parents.The heterosis of number of node and plant height was similar.The mid-parent heterosis(MPH) and the better parents heterosis (BPH) of pods per plant and seed number per plant had similar performance.Six combinations were negative in MPH of pods per plant and 8 combinations were negative in BPH of seed number per plant.Stem diameter is better in MPH.The majority of 100-seed weight in F1had higher BPH.Fat and protein content were between parents in majority of hybrid，and the majority of combinations were negative in BPH.
