semi-dwarf: Short dark green, sdw*-N2252, F2 mutant seedlings showing lighter green streaks and ridges. Internodes elongate to semi-dwarf stature. | Semi-dwarf: A Short Sdw*-N987B/+ heterozygous mutant plant showing short stiff leaves and progressive less shortening of all but the last 4 internodes; tassel restricted with tassel seed branches. Homozygote is typically dwarf. |
