This paper reported new progress on supper-high-yielding breeding in soybean.The object of super-high-yielding breeding was to develop new variety that had 5 000 kg/hm² seed yield potential.Several variety types were designed and selected:① Maximum leaf area index of canopy was 5.5.②Leaflet,branchy geem,tight trye varieties.③Semi-determinate dense-planting type.Experiment showed that more than 4 000 kg/hm² seed yield was easily obtained using these varieties and the super-high-yielding varieties had 5 000 kg/hm² yield potential.Pedigree analysis shown that local germplasm from Jilin province was only 1/16 to 5/16,germplasm from Heilongjiang and Liaoning province respectively1/4.Proportion of local germplasm in the super-high-yielding varieties was less than that in high-yielding varieties.
