摘要： 【目的】评价宁夏南部山区玉米品种的丰产性、稳产性、适应性以及各试点的鉴别力,筛选适宜该地区大面积推广种植的玉米品种。【方法】运用AMMI双标图及稳定性参数（品种稳定性参数为D_i、环境稳定性参数为D_j）对2023年宁夏南部山区晚熟玉米区域试验13个参试品种在6个试点的籽粒产量进行稳定性分析,并对试点的鉴别力进行评价。【结果】方差分析结果表明,参试玉米品种籽粒产量的品种、试点及品种与试点互作效应均达到极显著水平（P<0.01）。试点效应在总平方和中占比最大（83.89%）,品种与试点互作效应占比7.40%,品种效应占比1.73%。AMMI双标图和D_i参数显示,润丰969、银玉8333、KH385属于高产稳产品种;今成839、祺玉128、贺丰216、HY37丰产性一般且不稳产;金润889、科优219、富强235高产但稳产性一般;宁禾237、KY158稳产但丰产性一般。各试点对参试品种鉴别力不同,鉴别力最强的是隆德县试点、最弱的是西吉县试点。【结论】润丰969、银玉8333、KH385是高产稳产品种,适宜在宁夏南部山区大面积推广种植,隆德县试点对品种具有较强的鉴别能力。

Abstract: 【Objective】To evaluate the high-yield potential,yield stability,adaptability of maize varieties in the southern mountainous region of Ningxia,as well as the discriminatory power of each test site,in order to screen maize varieties suitable for large-scale promotion and cultivation in this region. 【Methods】AMMI biplot and stability parameters（variety stability parameter denoted as D_i,environment stability parameter denoted as D_j） were applied to analyze the stability of grain yield for 13 maize varieties tested in the regional trial of late-maturing maize across 6 test sites in the southern mountainous region of Ningxia in 2023,and to assess the discriminatory power of the test sites.【Results】The analysis of variance revealed that the effects of variety,test site,and variety-by-test-site interaction on grain yield of the tested maize varieties all reached extremly significant levels（P<0.01）. The test site effect accounted for the largest proportion of the total sum of squares（83.89%）,followed by the variety-by-test-site interaction effect（7.40%）and the variety effect（1.73%）. The AMMI biplot and D_i parameter indicated that Runfeng 969,Yinyu 8333,and KH385 were high-yielding and stable varieties;Jincheng 839,Qiyu 128,Hefeng 216,and HY37 exhibited moderate yield potential with poor stability;Jinrun 889,Keyou 219,and Fuqiang 235 were high-yielding but had moderate stability;while Ninghe 237 and KY158 showed good stability but moderate yield potential. The discriminatory power of the test sites varied among the varieties,with the Longde County site exhibiting the strongest discriminatory power and the Xiji County site the weakest.【Conclusion】Runfeng 969,Yinyu 8333,and KH385 are high-yielding and stable maize varieties,suitable for large-scale promotion and cultivation in the southern mountainous region of Ningxia. The Longde County test site demonstrates strong discriminatory capability for variety evaluation.
