The PH 1 W 6 W line is intellectual property and is not intended for sowing as a commercial variety. It is used by breeders as source material for crosses and the creation of other lines.
During the selection of this line, key criteria are lodging resistance, plant health at the end of the growing season, grain quality, ability to germinate under adverse conditions, and pollination indicators. Line characteristics, such as leaf blade width, are used for identification purposes when conducting distinctness, uniformity, and stability testing.
