Abstract:: 　 T he grey system theory was employed to study the effect of 12 importent agrionmic traits onfresh pod yield and the relationship among the trait adopted in the study.The results showed that the mostimportant limited factor for vegetable soybean production in Yunnan is biomass, which influenced by nodesper main stem , plant height , pods per plant and the duration from sowing to flowering .We suggest thatthe yield would be improved greatly by means of breeding and cultivating methods, such as introducing orselecting vigorous varieties with taller plant , more nodes, pods and longer growth period , promoting bio-mass via increasing plant density and adapted fertilizer , and improving cultivar distribution.
