我们对1985~1986年河南省夏播玉米区域试验的郑单八号等十个杂交种丰产性和稳产性参数及主要农艺性状进行综合分析,并作出较为客观准确的评价,同时对与之有关的问题进行了讨论。材料与方法参试种有郑单八号(黄早4×32)、豫单八号(3184×黄早4)、豫单九号(潍矮141×L34122)、全矮201×黄早4、安早3号(南繁51×黄早4)、植单抗螟一号(植 We conducted a comprehensive analysis on the yield and stability of 10 hybrids, including Zhengdan 8, in the field trials of summer sowing maize from 1985 to 1986 in Henan Province, and made a more objective and accurate evaluation of the hybrids. At the same time, The issue was discussed. Materials and methods Participants were Zhengdanhao No. 4 (Huangzao 4 × 32), Yuhan No. 8 (3184 × Huangzao 4), Yuhan No. 9 (Weizai 141 × L34122), all short 201 × Huangzao 4 , Ann early on the 3rd (Nanfan 51 × Huangzao 4), planting a single anti-borer on the 1st (plant
