soil. Choska averaged 3% higher yield than Forrest in 45 Oklahoma tests, where neither cultivar exhibited iron deficiency chlorosis. Choska yielded 3% less than Forrest in regional tests. In 17 Oklahoma tests, Choska averaged 8% higher yields than Sohoma. Choska is resistant to stem canker [caused by Diaporthe phaseolorum (Cooke & Ellis) Sacc. f. sp. meridionalis Morgan-Jones] and to root-knot nematode [Meloidogyne incognita (Kofoid & White) Chitwood], but susceptible to soybean cyst nematode (Heterodera glycines Ichinohe). It is also susceptible to the soybean looper [Pseudoplusia includens (Walker)]. It is tolerant to the herbicide metribuzin [4-amino-6-( 1,1 -dimethylethyl)-3-(methylthio)-1,2,4triazin-5(4fl)-one]. Foundation seed will be produced and distributed by the Oklahoma Foundation Seed Stocks, Inc., Dep. of Agronomy, Oklahoma State University, Stillwater, OK 74078. Pedigreed seed will be limited to one generation each of foundation, registered, and certified classes. The Oklahoma Agricultural Experiment Station will be responsible for maintenance of breeder seed. A small seed sample of Choska for research purposes may be obtained from the Oklahoma Agricultural Experiment Station for at least 5 yr by contacting the corresponding author.
