COMPOSITIONS AND METHODS FOR IMPROVING CROP YIELDS THROUGH TRAIT STACKING

摘要

The present disclosure provides modified, transgenic, or genome edited/mutated corn plants that are semi-dwarf and have one or more improved ear traits and yield relative to a control plant, such as increased ear area, increased ear volume, increased single kernel weight, increased ear fresh weight, increased ear diameter, increased ear length, increased yield, increased kernels per ear, decreased ear tip void, and decreased ear void. The modified, transgenic, or genome edited/mutated corn plants comprise a transgene encoding one or more CONSTANS (CO) or CONSTANS-like (COL) polypeptides and a transgene encoding one or more MADS-box polypeptides, and can also have a reduced expression of one or more GA20 or GA3 oxidase genes. Also provided are methods for producing the modified, transgenic, or genome edited/mutated corn plants.
