Aleurone blue. Kernels large. Growth vigorous. Yield high. Straw weak. Performance as malting variety unfavorable. Good resistance to several races of loose smut. Adapted to the Western and Midwestern U.S. Selected from a bulk lot of barley obtained from the south shore of the Black Sea in Asiatic Turkey. Apparently the bulk originated in Trebizond, Asiatic Turkey. The name for the variety was derived form this latter city. The selection now known as Trebi was made by H.V. Harlan in 1909. In 1913 Trebi was sent to Aberdeen, Idaho, and tested for a number of years in comparison with other varieties in cooperatives tests. Released from Aberdeen in 1918. | 1432378 | PI 537442 |
