The present study investigated the stability and adaptability of maize ( L.) hybrids. In this study, 12 maize hybrids were planted and examined considering the grain yield. The experiment was arranged in a randomized complete block design (RCBD) with three replications in four research stations in Iran during two crop years. The combined analysis of variance showed that genotype-environment interactions were significant at one percent probability level. The grain yield can stabilize, and hybrids with specific adaptability are recommended to each environment. Hybrids with specific adaptability can be recommended to all types of the environment. Means comparison yield of the genotypes identified DC370 as a high-yield genotype. Regarding AMMI analysis, genotype × environment interactions (GEIs) and two first components were found significant. The SC647 genotype was identified as the most stable genotype. Regarding the stability parameters, SC647 and KSC705 genotypes were selected as the most stable genotypes. From AMMI1 and AMMI2 graphs, the SC647 genotype was identified as the most stable genotype compared with other hybrids.
本研究调查了玉米杂交种的稳定性和适应性。在本研究中，种植了12个玉米杂交种，并考虑籽粒产量进行了检测。试验采用随机完全区组设计（RCBD），在伊朗的四个研究站进行了两个作物年度的试验，重复三次。方差的联合分析表明，基因型与环境的相互作用在1%的概率水平上显著。籽粒产量可以稳定下来，并向每个环境推荐具有特定适应性的杂交种。具有特定适应性的杂交种可推荐给所有类型的环境。基因型产量均值比较确定DC370为高产基因型。关于AMMI分析，发现基因型×环境互作（GEIs）和前两个主成分显著。SC647基因型被确定为最稳定的基因型。关于稳定性参数，SC647和KSC705基因型被选为最稳定的基因型。从AMMI1和AMMI2图来看，与其他杂交种相比，SC647基因型被确定为最稳定的基因型。
