Abstract:

9 so ybean cultiv ars that had di fferent g rowing period and pod bearing habit w ereuseded to study relatio nship betw een seed yield stabi li ty and g rowing period, pod bearinghabi t of so ybean cultiva rs. Ex periment resul ts show ed that in the middle pa rt of Jilinprovince, middle ma turing and simidetermina te cul tivar w as most stable under conditionsof 370- 740mm preciptation and a round 3000℃ accumula tio n tempera ture f romMay to Sep. . Under conditions o f combinatio n of annual di fferent climate co ndi tio ns,mean perfo rmance of seed yield stabi li ty of middle ma turing cul tiv ars w as bet ter thanthat of middle- la te and ea rly cultiv ars. The dif ference amo ng di fferent pod bearinghabi t cul tiv ars in middle maturing cul tivars was no t o bvio ns.
