WB4505 Hard Red Winter Wheat

Made to Thrive In The North

WB4505 is a Hard Red Winter Wheat variety that is appealing to growers due to its excellent yield potential and grain quality. The medium-maturing variety also has excellent test weight and winter hardiness.

Key Strengths

WB4505 offers excellent grain quality; excellent yield potential; very good Wheat Streak Mosaic Virus resistance; and very good Yellow (Stripe) Rust resistance.

"From a pure yield standpoint this variety has been at the top of the pipeline tests for quite a while. As we move west it’s neck and neck with KELDIN, which has been our best product in that Montana market. You really can’t distinguish them much from a yield standpoint, they’ve both been really good. But we think it is an improvement over KELDIN from a Yellow Stripe Rust standpoint, Wheat Streak Mosaic standpoint, and then the gluten strength and protein."

"WB4505 brings together a really nice overall package of winter hardiness, test weight, Wheat Streak tolerance, Yellow Stripe Rust resistance, good end use quality and drought tolerance. That’s a very formidable package as we target these western High Plains environments."
