Abstract:: The rela tionships betw een main ag ronomic characters a nd seed yield per plant of soy bean renewedreleased va rieties in Liao ning since the establishment of new China was studied. The general tendencyshow ed that amo ng 13 cha racters besides No. of branches all increased in di fferent lev el s. Pods of 3- seed, pods on bra nches, seed weight per pla nt , seed / stem ratio , plant height a nd nodes of main stem increasedsig nificant ly, and day s f rom emerg ency to maturity had only few increased. Genetic va riations indicatedthat pods of 3- seed, No. of branches and seed weight per plant w ere more sensitiv e to envi ronment.Co rrelatio n a nalyses showed that there exist direct correlativ e ef fects betw een seed weight per plantand pods per plant, pods of main stem, po ds on branches, 100- seed weight and seed /stem ratio. Pathanalyses show ed clearly tha t pods per plant had largest di rect effect s o n seed w eig ht per plant a nd w as themain facto r of ef fecting seed yield per pla nt.
