Narrative

Spring-type wheat. Resistant to Great Plains (GP) biotype but susceptible to a H13-virulent strain of Hessian fly. It is resistant to stem rust and moderately resistant to tan spot, but susceptible to Fusarium head blight. Has normal plant growth at the seedling stage, but it exhibited hybrid chlorosis at later stages. Chlorotic mottles usually appeared on older leaves and leaf sheaths after plants started the erect growth (about four weeks post planting). As plants grew, chlorosis gradually expanded to upper and younger leaves and sheaths. After the flowering stage, chlorosis gradually progressed to the whole plant and caused leaves and sheaths to senesce prior to plant maturity. The seeds were usually shriveled but viable. It averaged 81.6 cm in plant height.
