The RHA-R-PL-2/1 line is used in breeding programs as a tester to evaluate combining ability. It is utilized in the development of high-yielding hybrids, demonstrating significant indicators of specific combining ability for plant height and head diameter.
In scientific studies where this line is featured as a parental component, traits such as seed yield and oil content are analyzed. RHA-R-PL-2/1 represents breeding material, rather than a commercial hybrid intended for commodity planting.
