    摘要:

    用吉单27、先玉335和郑单958等3个品种作对照,对从美国引进的5个玉米新品种进行品比试验。结果表明,所有参试品种的产量均高于对照吉单27,除Y1301差异不显著之外,其余达到显著水平或极显著水平。尽管所有品种的熟期均比先玉335和郑单958早,但是,除Y1301之外,其余4个品种的产量均高于对照先玉335和郑单958,差异未达显著水平。试验证明引进品种具有较好的丰产性,直接引入品种是可行的,但需进一步做多年多点鉴定。

    Abstract:

    Jidan 27, Xianyu 335 and Zhengdan 958 were used as controls, 5 new maize varieties introducedfrom USA were compared. Results showed that the yields of all varieties were significantly or extremely significantlyhigher than control Jidan 27, except for Y1301, which difference was not significant. In spite of the growth period ofall varieties were matured earlier than Xianyu 335 and Zhengdan 958, but in addition to Y1301, yields of the rest 4varieties were higher than the control Xianyu 335 and Zhengdan 958, the difference was not significant. The experi-ment proved introduced varieties have good yield potential, so the direct introduction of varieties is feasible, but fur-ther screening on different sites is needed.
