我所利用辐射手段选育的小麦新品系77L_(15),经4年全省区试、生产示范试验,表现具有综合抗病性好、适应性强、丰产、稳产等特点。一、选育经过 1977年秋用氦—氖激光(激光输出功率2毫瓦、波长6328A°)5分钟辐射76(30)F_1,(郑引1号×山前第一代)风干种子,于温室盆栽,当代分离中有一个半矮秆的单株表现抗锈。1978年春分别在青海和当地温室连续加代繁殖。1978—1979年将加代收获的M_2F_3代54
The new wheat line 77L_ (15), which was bred by means of radiation, has been tested and produced in four years in the whole province. It has the characteristics of good comprehensive disease resistance, strong adaptability, high yield and stable yield. I. Breeding After the fall of 76 (30) F_1 with a helium-neon laser (laser output of 2 milliwatts and a wavelength of 6328A °) for 5 minutes in the fall of 1977, Potted, contemporary segregation has a semi-dwarf plant exhibiting rust resistance. Spring 1978, respectively, in Qinghai and the local continuous addition of greenhouses breeding. 1978 - 1979 will be the generation of M_2F_3 generation 54
