CHOTEAU - Derived from the cross of MT 9401/MT 9328. Choteau is a semidwarf hard red spring wheat with solid stems conferring tolerance to wheat stem sawfly. Choteau is resistant to the prevalent race of stem rust in Montana. Choteau has good grain protein and acceptable milling and baking quality.

DUCLAIR - Derived from a cross of Choteau//Reeder/Scholar. Duclair is a solid stem semidwarf hard red spring wheat with fewer solid stems than Choteau and generally has more solid stems than Fortuna. Duclair is resistant to the prevalent races of stem rust in Montana. Duclair exhibits good milling and baking traits.

VIDA - Vida was derived from the cross of Scholar/Reeder and is a semidwarf hard red spring wheat with white glumes and awns. Vida is moderately resistant to leaf and stripe rust but is moderately susceptible to stem rust. Vida has good milling and baking characteristics.

WB9879CLP - Derived from the cross of Choteau*3//Choteau/IMI8134 made in 2004 to be used as a two gene clearfield wheat. WB9879CLP heads about one and a half days later than Choteau while plant height is the same as Choteau. WB9879CLP has solid stems similar to Choteau. WB9879CLP exhibits acceptable milling and baking quality traits similar to Choteau. WB9879CLP is currently licensed to WestBred, a unit of Monsanto.

EGAN - Egan has resistance to the orange wheat blossom midge (OWBM). Egan has shown good yield potential in northwestern Montana, and has a relatively high grain protein content and resistance to stripe rust. Egan should be grown in a blend with a OWBM susceptible variety (90% Egan - 10% susceptible) to lessen the possibility that the OWBM will overcome the resistance.

LANNING - Released by the Montana Agricultural Experiment Station due to its yield potential in dryland areas of Montana and its superior end-use quality. Lanning was derived from the cross 'Glenn'/MT0747 by single seed descent beginning in the F₂ generation. Lanning has grain yield similar to 'Vida' with higher grain protein and stronger gluten characteristics than Vida. Lanning is hollow-stemmed, suggesting that it will be susceptible to damage caused by wheat stem sawfly.

NS PRESSER CLP - A hard red spring wheat (Triticum aestivum L.) developed by the Montana Agricultural Experiment Station and released in 2016 to the commercial partner Northern Seed LLC. NS Presser CLP is a two-gene Clearfield wheat intended for use with the selective imidazolinone herbicide imazamox (Beyond, BASF Corp.). NS Presser CLP was developed by a single backcross of alleles for resistance to the imidazolinone herbicide class into the recurrent parent 'Vida'. Yield trials at sites in Montana showed that NS Presser CLP has yield potential under dryland production similar to Vida.

DAGMAR - Has similar grain yield potential to 'Vida' (PI 642366), the most widely grown cultivar in Montana. Stems of Dagmar are more solid than those of Vida, suggesting increased resistance to wheat stem sawfly. Dagmar has higher grain protein and stronger gluten than Vida.

All varieties are covered by PVP and research fees are collected for: CHOTEAU, DUCLAIR, VIDA, EGAN, LANNING, and DAGMAR.
