摘　　要：Soybean(Glycine max[L.]Merr.)is an important crop that provides protein and vegetable oil for human consumption.As soybean is a photoperiod-sensitive crop,its cultivation and yield are limited by the photoperiodic conditions in the field.In contrast to other major crops,soybean has a special plant architecture and a special symbiotic nitrogen fixation system,representing two unique breeding directions.Thus,flowering time,plant architecture,and symbiotic nitrogen fixation are three critical or unique yielddetermining factors.This review summarizes the progress made in our understanding of these three critical yield-determining factors in soybean.Meanwhile,we propose potential research directions to increase soybean production,discuss the application of genomics and genomic-assisted breeding,and explore research directions to address future challenges,particularly those posed by global climate changes.
