中文摘要:
      对玉米区域试验数据进行基因型与环境互作分析,全面掌握参试品种丰产性和稳产性信息,对筛选适宜冀中南地区推广种植的优良品种有着重要意义。本研究借助AMMI模型和GGE双标图对2015年河北省夏播玉米区域试验中13个参试品种在10个试点的相关农艺性状进行分析,内容包括籽粒产量,穗长,穗行数,秃尖,千粒重。结果表明,各农艺性状在不同基因型和环境间存在极显著差异,基因型和环境间存在极显著互作效应。参试品种丰产性表现较好的有G7(龙华369)、G1(J1302)、G6(衡玉1182),丰产性表现较差的有G5(澳玉698),G2(JF33)。品种稳定性方面,G6(衡玉1182)、G1(J1302)、G8(荃玉18)、G13(郑单958)、G7(龙华369),G11(鑫研218)稳定性最差。丰产性、稳产性和适应性较好的品种有G1(J1302)、G6(衡玉1182)、G7(龙华369)。综合运用AMMI模型和GGE双标图,为河北省夏播玉米品种合理布局提供理论依据。
英文摘要:
      The analysis of genotype and environment interactions in the maize regional trial, knowledge on yield stability of the tested cultivars, and it is of great significance for screening suitable cultivars to plant in the central and south of Hebei province. In this study, An additive main effects and multiplicative interaction (AMMI) model and a genotype main effect (G) and genotype and environment interaction (GE) (GGE) biplot were used to analyze the related agronomic traits of 13 tested maize cultivars at 10 test sites during the regional trial in Hebei province, including grain yield, ear length, ear row number, baldness and 1000-kernel weight. The results showed that there were significant differences in agronomic traits between genotypes and environments, and there was a significant interaction between genotypes and environment. The yield performances of G7 (Longhua369), G1(J1302) and G6(Hengyu1182) were higher than others.Whereas,cultivars G5(Aoyu698) and G2 (JF33) had the lowest yield performance.The cultivars G6 (Hengyu1182), G1 (J1302), G8 (Quanyu18), G13 (Zhengdan958) and G7 (Longhua369) were more stable than others and G11 (Xinyan218) had lowest stability among all cultivars. According to comprehensive analysis, the cultivars G1 (J1302), G6 (Hengyu 1182) and G7 (Longhua 369) were better in yield performance, stability and adaptability. In conclusion, the combined used of AMMI model and GGE biplot provided more accurate analysis and assessment to provide a theoretical basis for the rational layout of summer maize cultivars in Hebei Province.
