青贮专用玉米品种新青1号产量稳定性分析

Analysis to Yield Stability of Xinqing No.1 of Silage Maize Variety

为了探讨青贮专用玉米品种新青1号的产量潜力和适应范围,采用DPS系统,按S.A.Ebechart和W.A.Russel提出的品种稳定性参数法,评估新青1号丰产性、稳定性和适应性,为品种推广及合理布局提供依据。结果表明,新青1号全株生物产量5 254.57 kg/666.7 m^2,比对照新多2号增产21.6%,6个试验点全部增产,位于参试品种首位。变异系数3.042579,回归系数1.2397。说明新青1号在参试品种中丰产性最好,增产潜力最大,稳定性最强,具有广泛的适应性。

In order to explore the Yield potential and Adaptation of Silage Maize variety Xinqing No.1, DPS system and the method of Variety Stability Parameters proposed by S.A.Ebechart and W.A.Russel.are used to provide a basis for the promotion of rational distribution. The results show that the whole plant biomass yield of Xinqing No.1 is 5 254.57kg/666.7m2, and increases by 21.6%, higher than other six test stations that are also increase the yield. The variation coefficient is 3.042579 and regression coefficient is 1.2397. It shows that Xinqing No.1 is with best yield potential and strongest stability as well as a wide range of adaptability.
