Interpretive Summary: 'Sturdy 2K' is a hard red winter, semidwarf wheat, having strong straw, resistance to shattering, durable leaf rust resistance, and very good forage production. 'Sturdy 2K' was developed by TAES-Dallas from a selection out of 'Sturdy', a variety released for production in Texas in 1966. The original 'Sturdy' was the first semidwarf, hard red winter wheat available for growers in the United States. At the time of its release from TAES-Amarillo, 'Sturdy' was heterogeneous for resistance to leaf rust. Scientists at TAES-Dallas selected and purified individual lines from 'Sturdy' specifically having genes for long-lasting leaf rust resistance. 'Sturdy 2K' is not immune to leaf rust, rather leaf rust can only grow very slowly on 'Sturdy 2K', never reaching damaging levels. 'Sturdy 2K' has very good hard red quality and is adapted to all wheat growing regions of Texas, with the exception of far, southeast Texas, where the variety may not vernalize properly.
