Abstract:: Prog enies of tw o- pa rent、four - pa rent、eight- parent a nd six teen- pa rentcrosses made wi th 43 good parents w ere compared on perfo rmance and selectionrespo nse of thei r ag ro nomic t rai ts. The objectiv e o f this study w as to ex plore theef fectiv eness o f dif ferent parental numbers o n g enetic v ariatio n and mean perfo rmance ofthe filial- genera tions, and to provide theo retical bases for parental mating and prog enyselectio n in soy bean breeding.The experimental resul ts show ed that: In the crosses co ntaining mo re pa rentalnumbers, yield- trai t variation o f prog enies w ere compa ra tiv e large. This sugg ested thatincreasing parental numbers of crosses seemed to be able to increase va riation ofprog enies. The trait s relatively simply inherited ex hibi ted thi s t rend mo re apparentlythan the relativ ely complex genetic characters.
