7118—1是我所育种研究室冬麦课题组1971年用“5702”作母体,61(3)/27—6—5作父本杂交,经五年系统选育而成。7118—1与7118—2(张冬9号)是姊妹系。经1977、1978两年的品系鉴定、比较,均具有抗寒力强,灌浆速度快,千粒重高,中早熟,产量高等特性。1978年参加地区区试,在参试的十一个材料中,亩产1027.3斤,比对照晋农27增产51.5％,比7118—2增产4.5％。1979—1981年连续三年参加本地区区试,共设45点次,在有总结材料的29次中,位居1、2、3位的有20次,增产的有25次,减产的4次,平均单产908.4斤,平
7118-1 is my breeding research group winter wheat research group in 1971 with “5702” as the mother, 61 (3) / 27-6-5 as the male parent, after five years of system selection. 7118-1 and 7118-2 (Zhang Dong 9) are sisterhoods. After 1977,1978 two years of identification and comparison of strains, have strong cold resistance, filling speed, grain weight high, early maturity, high yield characteristics. In 1978, he took part in the regional test. Among the eleven materials tested, 1027.3 kg per mu were produced, 51.5% more than the control Jinnong27 and 4.5% more than the 7118-2. 1979 - 1981 for three consecutive years to participate in the regional test, a total of 45 points, there are 29 summary materials, ranking 1, 2, 3 20 times, increase 25 times, cut 4 Times, the average yield of 908.4 pounds, flat
