(一)选育过程1961年春由内蒙物理研究所协助用钴60(γ射线)处理品种间杂交种“赤交26号”(斯吐吉娜×白穰铁岭黄)第一代种子。剂量:2千、4千、6千、8千、1万、2万仑琴共6个处理。1961年及1962年同剂量内进行选株采粉混交繁殖。1963年在2千仑琴剂量的一个穗行小区里抽雄期发现有4株不孕,即:—29、—9、—33、—17株,当即选择本小区内可孕株—30、—35、—32
(A) Breeding process The spring of 1961 was assisted by the Inner Mongolia Institute of Physics in the treatment of the first generation of seeds of the hybrid “Zajiao 26” (Sijinajina × Baitie Tielinghuang) with cobalt 60 (γ-rays). Dosage: 2 thousand, 4 thousand, 6 thousand, 8 thousand, 10,000, 2 million Lun Qin a total of six treatment. 1961 and 1962 within the same dose of selected strains of mixed powder breeding. In 1963, at a heading rate of 2 gullen, four infertile plants were found during the tasseling stage, ie -29, -9, -33 and -17, 35, -32
