试验对新选的14个玉米杂交种和郑单958进行比较.结果表明,杂交种1号、2号、5号、8号、9号、11号、14号和15号在农艺性状、产量性状和抗病性上均优于对照,方差分析呈极显著水平,可以申报山西省或国家区域试验和生产试验;杂交种7号、10号和12号产量比对照极显著增加,但其他性状表现一般,建议继续进行试验;杂交种6号产量虽高于对照,但没有达到极显著水平,建议淘汰;杂交种4号和13号无论产量还是其他性状均不及对照,也建议淘汰.
The comparison tests between the new 14 corn hybrids and Zhengdan 958 indicate that hybrid 1, 2, 5, 8, 9, 11, 14 and 15 are better than the reference in agronomic, yield and disease resistant traits with obvious analysis results of variance, making them ready to apply for Shanxi provincial or state-level tests and production tests.Hybrid 7, 10 and 12 show ordinary performances in other traits except higher yields, and more tests are suggested.Hybrid 6 results in a better yield but not in an obvious way, while 4 and 13 fall behind the reference both in yield and other traits, and all of these three are advised to be eliminated.
