优质高产啤酒大麦新品种陇啤1号是从匈牙利品种Jaxana中选择优异的变异单株培育而成,为二棱皮大麦,春性,生育期110 d左右,株高70～85 cm,穗长7.7 cm左右;穗粒数22粒左右,绝干千粒重43～45 g,绝干蛋白质9.7%～11.0%,2.5 mm筛选率在91%以上,浸出物(以干基计)达到81.8%、α-氨基氮为160 mg/100 g、糖化力为355.5WK,库尔巴哈值为42.4%,在两年甘肃省多点试验中,陇啤1号平均产量577.6 kg/667 m2,较对照品种甘啤4号、甘啤5号产量522.54 kg/667 m2,增产55.06 kg,增幅达10.54%,居参试品种第1位。与甘啤5号、甘啤4号相比较,具有丰产、抗逆、优质和广适等特点,不仅适宜甘肃省河西、“沿黄”、“引大”灌区和中南部雨养旱作区种植,也适宜于北方同类大麦种植区种植。
High-quality and high-yield beer New barley variety Long-gong 1 was cultivated from a variety of excellent varieties selected from the Hungarian variety Jaxana. It is springy, with a height of 70-85 cm and a spike length of 110 cm About 7.7 cm, the number of grains per spike was about 22, the dry weight was 43-45 g, the percentage of absolutely dry protein was 9.7% ~ 11.0%, the screening rate of 2.5 mm was above 91%, and the extract was 81.8% - amino nitrogen was 160 mg / 100 g, saccharification power was 355.5WK, and Kulba ha value was 42.4%. In the two-year Gansu multi-point experiment, the average yield of Longteng 1 was 577.6 kg / 667 m2, The output of Ganpi 4 and Ganpi 5 was 522.54 kg / 667 m2, an increase of 55.06 kg, an increase of 10.54%, ranking No.1 in the tested varieties. Compared with Ganpi No.5 and Ganpi No.4, it has the features of high yield, resistance, high quality and wide adaptability, which is not only suitable for Hexi, Gansu Province, Dry land for planting, but also suitable for planting similar northern barley growing areas.
