河北省农科院粮油作物研究所育成。是依据基因重组的原理,在玉米自交系黄早四繁殖田的大群体中。采用选择非典型的优良单株自交的方法,经过多年异地自交选择与人工接种鉴定育成了黄早四—15。该系保持了亲本黄早四配合力高与抗青枯能力强,还具备了抗小斑病、褐斑病的性能,且自身产量也提高了32.8％。目前该系已在玉米制种中应用,并取得了显著的经济效益、社会效益。

Hebei Academy of Agricultural Sciences Institute of grain and oil bred. Is based on the principle of gene recombination in the corn inbred line Huangzao four breeding fields in large groups. The method of inbred selection of excellent atypical plants was used to cultivate Huangzao-15 after many years of self-selection and artificial inoculation. The department maintained its parents Huangzao 4 with high ability and anti-brownstock ability, also has the resistance to small spot disease, brown spot disease performance, and its own production also increased by 32.8%. At present, the department has applied corn seed production and achieved significant economic and social benefits.
