‘H3860224’, a two-rowed spring feed barley (Hordeum vulgare L.) (Reg. no. CV-300, PI 619102), was developed by the Montana Agricultural Experiment Station and released for commercial production in February 2002.

H3860224 was selected from a cross of ‘Lewis’/‘Apex’ made at Bozeman, MT, in 1982. The parent Lewis (CIho 15856), a two-rowed barley, was developed by ARS and Montana State University from the cross ‘Hector’/‘Klages’. The parent Apex is a two-rowed barley cultivar developed by Cebeco Zaden B.V. in the Netherlands.

H3860224 originated at Bozeman from F3 plants selected in 1985 that provided seed for two-rowed F4 plots in 1986. One of these F4 plots was selected for replicated yield trial evaluation and was named ‘MT860224’. Following 4 yr of evaluation, 60 F8 headrows were evaluated from the MT860224 population. The third entry in this group of lines became H3860224. H3860224 is midseason in maturity with midlax, midlong spikes with rough awns that are seminodding to erect before and after maturity, similar to Apex. Kernels have adhering, finely wrinkled hulls, white aleurone, and rachilla hairs are short. Glume awns are equal to the length of the moderately hairy glume. H3860224 flowers nearly 2 d later than its maternal parent, Lewis (Table 1) . H3860224 is approximately 2 cm shorter than Lewis at maturity (Table 1). H3860224 has been found to be resistant to existing races of stripe rust (caused by Puccinia striiformis Westend. f. sp. hordei) in trials at Cochabamba, Bolivia (W.M. Brown, V. Velasco, and J.F. Hill, personal communication).

H3860224 has been widely tested in both dryland and irrigated trials in Montana since 1993. It was tested in trials in Idaho in 2001. In 72 location-years trials on dryland and under irrigation in Montana in 1993 to 1999, H3860224 out yielded all commonly grown cultivars (P < 0.01) except ‘Baronesse’, ‘Stark’, and ‘Valier’ (Table 1). H3860224 also produced a higher proportion of plump kernels than other commonly grown cultivars, except Stark (Table 1).

Foundation and Breeders seed of H3860224 will be maintained by the Montana Foundation Seed Program. Foundation and Registered seed will be available to growers and seed dealers in the spring of 2002. Seed is available in small quantities for research purposes from the corresponding author.
