华玉2号是华中农学院农学系用“双MO17CMS×自凤1”育成的恢复型雄不育、抗病、高产、中熟杂交玉米新组合。1979年在湖北的11个点进行试验,平均亩产939.8斤,比豫农704(对照)增产24％。在以后的各次湖北省区试中,它都比豫农704增产显著,1981年以后在各地的生产试验、试种和示范中,比当地的推广杂交种分别增产6.6—51.9％,表现高产稳产。1985年7月,湖北省农作物品种审定委员会常委会通过了对“华玉2号”的审定意见,推荐 Huayu 2 is a new combination of restorer male sterility, disease resistance, high yield and medium maturity hybrids bred by Department of Agronomy, Huazhong Agricultural College with “double MO17CMS × Zi Feng 1”. In 1979, 11 trials in Hubei were carried out, with an average yield of 939.8 kg per mu, an increase of 24% over that of Yulong 704 (control). In each subsequent trial of Hubei Province, it increased yield significantly than that of Yuinong 704. After 1981, it increased yields by 6.6-51.9% over that of its local counterparts in production trials, trials and demonstrations, showing high yields Stable production. July 1985, Hubei Province, the Standing Committee of Crop Variety Approval Committee adopted the “Huayu 2” approved the views of the recommended
