Breeding and selection Crosses for Sunland were made at Castle Hill. Cycles of single plant selection at Narrabri combined with rust evaluation at Castle Hill were conducted between 1982 and 1987. Regional yield and quality evaluation was conducted between 1988 and 1991. Final rust evaluation was conducted at Cobbitty. Morphology Sunland is a white-seeded, spring wheat that has large, white, fully awned ears.
Early growth is semi-erect.
The auricles are white and smooth. Sunland is a semi-dwarf wheat that is slightly taller than Hartog and has medium straw strength. Sunland flowers 2 days earlier, and matures 1-2 days earlier, than Hartog. The postulated genes for stem rust resistance are Sr 5, Sr 9e, and Sr 36. Sr 9e and Sr 36 combined provide a high level of resistance.
