“津丰1号”是1970年用钻60伽玛(Υ)射线10,000伦琴剂量,辐射“石家庄63”干种子,经6代选育而成。它的主要特点是:株型紧凑,叶色深绿,叶片挺立,抽穗前旗叶上冲,开始灌浆转为下垂;株高70厘米左右,秆壁厚、机械组织发达,因而秆硬,加上秆矮,抗倒伏能力强,生长、抽穗整齐,下层穗少;早熟,在天津试种3年,成熟期都在6月10—13日,比当前推广品种一般早熟4—5天;千粒重较高,通常为40—45克;籽粒白色,角质,皮薄,蛋白质含量达15.71%;高抗条锈,中感叶锈。弱点是抗寒性稍弱(在天津),生长后期易感白粉病和遭蚜虫为害,成熟时易落粒,种子休眠期短。“津丰1号”具有一定的增产潜力。1975年天津 Jinfeng No. 1 was drilled in 1970 with a dose of 10,000 Ruanqin on a drill 60 gamma (γ) ray and radiated “Shijiazhuang 63” dry seeds and was bred from 6 generations. Its main features are: plant compact, dark green leaves, leaves stand upright, heading flag on the red before heading, began to pour into sagging grouting; plant height of about 70 cm, stalk wall thickness, mechanical tissue developed, and thus stalk hard, plus Short stalk, strong resistance to lodging, growth, heading and tidy, lower spike less; precocious, three years of trial in Tianjin, mature in June 10-13, 4-5 days ahead of the current promotion of varieties generally; High, usually 40-45 grams; grain white, horny, thin skin, the protein content of 15.71%; high resistance to stripe rust, leaf rust in the sense. Weaknesses are weaker in cold resistance (in Tianjin). Susceptible powdery mildew and later aphid infestation in the late growth stage are easy to fall off when mature, and the seed dormancy period is short. “Jin Feng 1” has a certain yield potential.
