Abstract:
In this article , much work has been done for study ing the strain of soybean , totally including 10 v arietiesf rom the three provinces of north -east China and Yangt ze river area .Somatic embryogenesis w as inducedby immature co tyledons in Ms medium containing 2 , 4 -D(40mg/ L)for four w eeks and then t ransferred to theMs medium containing 2 , 4 -D(20mg/L)for another four weeks .The relat ionship of ag ronomic characters andfrequency of callus and somatic embtyogenesis was studied .The result showed that the 100 -seed weig ht is significant positively correlated w ith the size of the explant (r =0 .989593), and the effect of them to the embry ogenesisare all significant .The effect of growing stage and the time of the choice of explant is sig nificant also ,and the correlation between them is significant posi tively (r =0 .964764).The scope in the choice of explant canbe decided acco rding to the ag ronomic characters of different genotype soybeans.
