| 中文摘要: |
| 以7633-112-1作母本，蒙燕146作父本，采用有性杂交技术和系谱选育法，在20多年选育试验基础上培育出定莜6号新品种。试验鉴定结果表明：与定莜1号相比，该品种区试增产14.1%，平均产量2 022.6 kg/hm2；株高66～120 cm，穗长13～26.5 cm，千粒重17.6～22.8 g，生育期85～113 d；粗蛋白含量20.86%，粗脂肪7.25%，赖氨酸0.886%，亚油酸43.47%(占不饱和脂肪酸比重)；抗旱性强，丰产性好，品质优，抗坚黑穗病，适宜在甘肃中部干旱半干旱山区及同类地区推广种植。 |

| Taking 7633-112-1 as mother plant and Mengyan 146 as father plant, we used sexual crossing technology and pedigree selection method, and finally cultivated a elite dryland oat variety-Dingyou 6. The results showed that: In regional test, the yield of Dingyou 6 raised averagely by 14.1% compared with Dingyou 1, resulting in average production of 2 022.6 kg/hm2; The date of stem height, ear length, thousand-grain weight, growth period, crude protein content, crude fat, lysine, linoleic(percentage in unsaturated fatty acids) was respectively 13～26.5 cm, 17.6～22.8 g, 85～113 d, 20.86%, 7.25%, 0.886%, 43.47% and 66～120 cm; In addition, it has many other advantages, such as strong drought resistance, high output, super quality, anti-dustbrand, and suitable for arid and semiarid areas or similar areas of middle part of Gansu. |
