【摘要】 燕麦新品种航燕1号是以经搭载航天育种卫星"实践八号"产生的诱变材料为基础,用"低代(SP1~3代)混系多向选择与高代(SP4~6代)集团定向选择"相结合的方法经多年选育而成。在2011—2013年的多点区域试验中,航燕1号平均折合产量为2 646.0 kg/hm2,较主对照品种定莜2号增产15.8%,较副对照品种会宁莜麦增产45.6%。生育期97 d,平均株高117.5 cm,千粒重25.0~29.2 g。籽粒含粗蛋白(干基)197.1 g/kg、粗脂肪(干基)82.6g/kg、粗淀粉(干基)613.7 g/kg、β葡聚糖47.3 g/kg。活秆成熟、粮饲兼用特性突出。适宜在白银市干旱、半干旱雨养农业区及同类地区种植。更多还原

【Abstract】 Hangyan 1 is a newly oat variety on the basis of the mutagenic material carrying space satellite Shijian 8 in the way of combining low generation(SP1~3 generations)mixed multidirectional selection with high generation(SP4~6)group selection to breed in many years. In 2011—2013,the average yield of Hangyan 1 reaches 2 646.0 kg/hm2,which is 15.8% higher than that of the main contrast variety of Dingyou 2,and 45.6% higher than that of the deputy contrast variety of Huining oat. The result shows that the growth period of Hangyan 1 is 97 days,and the average plant height,thousand kernec weight,grain protein(dry basis),fat(dry basis),starch(dry basis),β-glucan are 117.5 cm,25.0~29.2 g,197.1 g/kg,82.6 g/kg,613.7 g/kg and 47.3 g/kg,respectly. The stem of Hangyan1 is living in mature,and the features of grain feeding combination are prominent. It is suitable to be grown in the region of the arid and semiarid rainfed areas of Baiyin and the similar areas.更多还原
