The object is a specialized breeding line intended for hybridization programs. The "PH...A" format designation indicates the plant's role as a parental component in the breeding process, rather than as a commercial hybrid for mass cultivation.
Specific agronomic and morphological traits, such as maturity group, plant height, or resistance indicators, are not detailed in open publications, as such parental forms are intellectual property.
