根据遗传学原理,将6个具有不同遗传背景的亲本,经过组配—选择—再组配—再选择以及辐射等方法,使多个早熟材料的早熟基因以及其它目标性状逐步重组、累加,选育出集早熟、抗寒、高产、优质于一体的冀麦 37号新品种。该品种一般产量为 6 000～7 500 kg/hm~2,与对照相当,高的可超过 9 000 kg/hm~2。熟期较对照早 4～5 d,能为下茬多提供积温 100～130℃。它的育成填补了河北省冀中南两熟制种植区早熟冬小麦品种的空缺。在河北、山东、新疆等省(区)累计推广面积 930 000 hm~2。1995年新疆定名为新冬 20,1996年河北省认定为冀麦 37号。1997年获河北省科技进步二等奖。
According to the principle of genetics, six parents with different genetic backgrounds were gradually recombined, accumulated and selected by the method of combination-selection-reassembly-re-selection and radiation Bred early maturity, cold hardiness, high yield, high quality in one of Ji Ma 37 new varieties. The general yield of this variety is 6 000 ~ 7 500 kg / hm ~ 2, which is comparable to the control and can exceed 9 000 kg / hm ~ 2. Maturity earlier than the control 4 ~ 5 d, to provide more accumulated temperature below 100 ~ 130 ℃. Its breeding has filled the vacancy of early-maturing winter wheat varieties in the two-cropping system in Jizhongnan of Hebei Province. In Hebei, Shandong, Xinjiang and other provinces (autonomous regions), a total area of 930 000 hm ~ 2 has been popularized. In 1995, Xinjiang was designated as Xin Dong 20, and in 1996 Hebei Province was designated as Ji Ma 37. In 1997 by Hebei province science and technology progress prize two.
