新黄单85—1(京7×U8)是一个特紧凑型中早熟玉米杂交种,原新乡地区农科所1984年育成,经1985年及1986年两年试验、示范结果,均表现丰产性好、抗逆性强、且品质优良,很受群众欢迎。 (一)产量结果:1985年在本所两项试验中平均亩产617.5公斤,分别较鲁玉6号和烟单14增产19.6％和27.8％;1986年参加本所承担的北方玉米杂交种区域试验(早熟组),在每亩4000株的情况下,亩产647.5公斤,名列第一,比对照种鲁原单8号亩产521公斤,增产24.3％,分别比参试种郑单8号,商单3号(豫玉1号)增产6.8％,8.3％。同年在焦作市郊区种子公司主持的两项
Xinhuang single 85-1 (Beijing 7 × U8) is a special compact early maturing corn hybrids, the original agricultural Bureau of Xinxiang Prefecture bred in 1984, after 1985 and 1986 two years of trial and demonstration results, all showed high yield Good, strong resistance, and good quality, very popular with the masses. (I) Output results: In 1985, the average yield per mu of 617.5 kilograms in two experiments of our institute was 19.6% and 27.8% higher than that of Luyu 6 and Yandan 14 respectively. In 1986, we participated in the northern corn hybrid region Test (early-maturing group), in the case of 4,000 strains per mu, 647.5 kg per mu, ranked first than the control Luyuan single No. 8 per mu 521 kg, an increase of 24.3%, respectively, than the test species Zheng 8 , Shang Dan 3 (Yu Yu 1) increased 6.8%, 8.3%.
