fusiform, middense to lax and tends to nod slightly at maturity. The awns are white, while the glumes are white to tan in color and glabrous. Kernels are short and ovate with a mid-sized brush. Cheeks are round and the crease is narrow. Hi-Line is hollow-stemmed and susceptible to the wheat stem sawfly (Cephus cinctus Nort.). It is resistant to prevalent races of stem rust caused by Puccinia graminis Pers. : Pers., and is susceptible to leaf rust caused by Puccinia recondita Roberge ex Desmaz. and stripe rust caused by Puccinia striiformis Westend. Hi-Line is midseason in maturity, averaging 3 to 4 d earlier than 'Newana', which is the most widely grown hollow-stemmed variety in Montana. Hi-Line may contain =0.3% plants that are 5 to 13 cm (2-5 in) taller than the modal plant height, as is the case with the Shortana parent. Grain yield of Hi-Line is similar to Newana and superior to most other cultivars recommended for production in Montana. Test weight of Hi-Line is approximately equal to Newana. Percent grain protein has averaged =1.1% higher than Newana over 5 yr of testing at 11 locations. Hi-Line has higher flour yield than Newana but lower than other spring wheat cultivars recommended for the state. However, the overall milling and baking characteristics of Hi-Line are equal or superior to Newana and other widely grown cultivars. Superior percent grain protein and good milling and baking qualities provided justification for the release of Hi-Line. Breeder seed was harvested in 1990 at Bozeman. Breeder and foundation seed will be maintained by the Plant and Soil Science Department, Montana State University, Bozeman, MT 59717.
