摘　　要：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 bio-genetics, 6 germplasms with different genetic background were crossed-selected-recrossed-reselected and combined with radiation, so different early genes and other target characters were recombined and accumulated, and Jimai 37 was developed with characters of early-maturity, winter resistance, high yield and good quality. Its yield level is 6 000-7 500 kg/hm2, maximum is 9 000 kg/hm2, same as the check variety, and mature date is 4-5day's earlier than the check variety, so it can save up 100 - 130℃ temperature for the next crops. Jimai 37 was released and planted 0. 93million hectares accumulatively in Hebei, Shandong and Xinjiang provinces or autonomy. It was named as Xindong 20 in Xinjiang autonomy in 1995, and Jimai 37 in Hebei province in 1996. It was rewarded the second prize in science and technology progress by Hebei Science and Technology Committee in 1997. It was also entered the list of key extension project of achievements in science and technology by the provincial and national committee of science and technology in 1997 and 1998 respectively.
