武宁县山地辽阔,发展玉米生产潜力很大。原伊山等乡虽有少量种植,但因品种不理想,产量低,抗性差,群众不愿扩种,鉴于以上情况,我所自1983年开始,从全国各地陆续引进优良玉米单交组合16个,经3年观察比较,认定华玉二号可适合我县大力推广。 华玉二号是华中农学院选育的恢复型雄性不育系单交种,由于是雄性不育系杂交种,制种简单,种子生产成本低,质量好,增产潜力大,深受广大农户欢迎。 1.产量高、潜力大 华玉二号参加我所品比试验(中肥组),产量居第一位,亩产693斤,比对 Wuning County, a vast mountain area, the development of corn production potential. Although the original Yishan Township, such as a small amount of planting, but the species is not ideal, low yield, poor resistance, the masses do not want to expand, in view of the above, I since 1983, from all over the country introduced fine corn single cross combination 16 A, after 3 years of observation and comparison, that Huayu two may be suitable for my county to promote. Huayu No. 2 Huazhong Agricultural College breeding single male sterile line of single cross, because it is a male sterile line of hybrids, seed production is simple, low cost of seed production, good quality, large potential for production by the majority of farmers welcome. 1. High yield, potential Huada Yu II to participate in my ratio test (fertilizer group), yield first place, 693 kg per mu, compared with
