Abstract:

Through identi fica tion and ev alua tion of 200 accessio ns by field ex periment and 100o f 200 accessions by g reenhouse ex perment fo r ag romomic, phenological and symbio ticcha racters. The result s indica ted: 1) . Sig nificant di fferences ( p < 0. 05) were present innodula tion a nd N2-fixa tion by bo th di fferent soy bean ty pes and dif ferent cultiv ars.These sugg ested it is po ssible tha t soy beans can be selected for improving nodulationand N2 fixa tion. 2) . Correlatio ns w ere sig nificant ( p < 0. 05) no t only among symbio ticcha racters themself , but also betw een symbio tic characters and ag ronomic /pheno logicalcha racters. The correlatio n may prov ide scientific da ta fo r researches in g enetic andphysio lgical bases for improving N2 fix atio n and hig h yield under di fferent co ndi tion ofseasons a nd cro pping systems in So uthen China. 3) . On the whole, the three so ybeanty pes w ere summer> autumn> spring in parameter va riations of ag ronomic, phenologicaland symbiotic characters. It may be complement for genetic div ersity and classi fcationo f soy beans. 4) . Some bet ter cultiva rs o f spring , summer a nd autumn soybeanshav e been evaluated w hich can be used in productio n a nd research.
