降低小麦茎秆高度,是在高肥水栽培条件下获得小麦高产的重要途径之一。“矮变一号”是陕西省西安市农科所于1972年从“矮秆早”小麦中选得的天然变异株。该品种具有冬性较强、矮秆性稳定、株高为26～29厘米、穗大、叶片挺等特点。1976年引入我所,除广泛用作矮秆亲本外,并进行矮秆遗传特性研究。 Reducing the height of wheat stalks is one of the important ways to obtain high yield of wheat under high fertilizer and water culture conditions. “Dwarf No.1” is a natural variant selected from the “dwarf wheat” in 1972 by Xi’an Agricultural Science Institute of Shaanxi Province. The varieties have strong winter, dwarf stable, height 26 ~ 29 cm, spike, leaves and so on. I was introduced in 1976, in addition to widely used as dwarf parents, and dwarf genetic characteristics of the study.
