reduced internode 1 shortens internode length while increasing soybean yield

Achieving high crop yields to meet the increasing food demands of a growing population has long been an important breeding goal and will continue to be so in the future.The grain yield per unit area of wheat and rice gradually increased from 1961 to 2021,with maximum increases of 2.21-and 1.55-fold,respectively(Figure 1A;source:https://www.fao.org/home/en/).During this period,breeding and selection gave rise to the so-called Green Revolution(GR)dwarf/semi-dwarf elite varieties of rice and wheat with remarkably increased yields.
