一、内麦五号的选育经过: 内麦五号系小麦育种课题组用(欧柔×辽春一号)F_1×如罗复式杂交第一代选株的干种子经CO~(60)γ射线二万伦琴的剂量照射后又经连续的单穗及单株选择培育而成。其具体选育经过如下: 育种工作开始于文化大革命前,当时我区水地小麦的育种目标是抗锈、抗倒、丰产。鉴于生产用种甘肃96号抗锈性丧失,丰产性亦逐渐退化,迫切要求新的良种进行更换。一九六五年智利小麦欧柔引入我区后深受群众欢迎,在生产上迅速推广。但是一般认
First, Neimes fifth breeding: Neimes fifth wheat breeding group (Osuron × Liao Chun-1) F_1 × such as the Luo Fu hybrid first generation of selected seeds by CO ~ (60) Gamma ray two million Roentgen doses after irradiation by successive single ear and single plant selection from training. The specific breeding process is as follows: Breeding began before the Cultural Revolution, when the water of wheat breeding in our region is the goal of rust, anti-down, high yield. In view of the loss of anti-rust properties of Gansu 96, which is used for production, the high yield is gradually degenerated, and new varieties are urgently required to be replaced. In 1965, after introducing the European wheat from Rouqiu to Chile, it was well received by the masses and rapidly popularized in production. But generally recognized
