OKFIELD

(Research Number OK02909C)

providing resistance to imidazolinone (Beyond) chemical.

Okfield has a relatively large kernel size but test weight is average.  It is a moderately tall semi-dwarf with about the same straw strength as Ok101.  It is resistant to powdery mildew in adult plants.

Okfield is intermediate in acid-soil tolerance, Moderately susceptible to wheat soil-borne mosaic, stripe rust, stem rust, septoria leaf blotch, and tan sport.  It is susceptible to leaf rust.

Okfield should appeal to grain-only and dual-purpose producers who place greater emphasis on winter grazing potential and grain production.  Forage accumulation in early fall is average but forage regrowth during the grazing period and recovery from grazing are above average.

Adaptation to dual-purpose systems that emphasize grain production following grazing throughout central and Western Oklahoma is a strong suit of Okfield.  Stand establishment will likely be delayed for Okfield when planted extremely early or in hot soils compared with rapid emerging varieties like Jagger and Ok101.
