Judee is a solid-stemmed hard red winter wheat with improved yield potential (Tables 1, 2) relative to Rampart. Judee was developed by the Montana Agricultural experiment Station and released to seed growers in 2011. Judee's pedigree is Vanguard/Northstar//Judith dwarf/3/ NuHorizon. Judee is a white-glumed, semi-dwarf (Rht1) wheat with medium maturity. Judee performs well in locations where sawfly cutting has occurred (Table 3). Stem solidness is good, intermediate between Rampart and Genou. Judee has average test weight and protein, and below average winter hardiness (Table 4). Judee is susceptible to prevalent races of leaf rust and stem rust, but resistant to stripe rust. Judee is a high PPO variety with average bake properties (Table 5). Montana State University Research Feed due on seed sold. PVP Title V has been issued (Certificate #2012001610.

Warhorse is a solid-stemmed hard red winter wheat with improved yield potential (Tables 1, 2) relative to Genou and Rampart. Warhorse was developed by the Montana Agricultural Experiment Station and released to seed growers in 2013. Warhorse was derived from a composite of three F1 crosses with a common parent, Nuplains/MTS9862 (an experimental sawfly line) crossed to three Montana unreleased hollow- and solid-stemmed experimental lines. Warhorse is an awned, white-glumed, semi-dwarf (Rht1) wheat with medium maturity. Warhorse performs well in locations where sawfly cutting has occurred (Table 3). Stem solidness is similar to Bearpaw and Rampart. Warhorse is resistant to prevalent races of stripe and stem rust, but susceptible to leaf rust. Warhorse is a high PPO variety with average mill and bake properties (Table 5). To be sold by variety name only as a class of certified seed. Montana State University Research Fees due on seed sold. PVP Title V has been issued (Certificate #201400131).
