摘　　要：旨在准确、合理的评价基因型与基因型？环境互作效应（G？E）对薏苡产量稳定性及地点鉴别力的影响,为优良品种的鉴定、推荐和登记提供科学依据。采用AMMI模型结合双标图及稳定性参数Dg（e）对第二轮（2012-2014年）国家薏苡区域试验的产量数据进行了分析。结果表明,G1~G6在不同试点的产量变异范围分别：2380.0~6061.0 kg/hm2、1933.3~5790.0 kg/hm2、2192.0~5632.3 kg/hm2、905.3~5485.7 kg/hm2、978.3~4680.0 kg/hm2、991.0~5340.0 kg/hm2;基因型效应、环境效应和基因型×环境交互效应（G×E）均达到极显著或显著水平,环境效应占总变异的55.10%,G×E交互效应占14.03%,基因型效应占8.41%,IPCA1、IPCA2和IPCA3分别解释了交互作用（G？E）的60.97%、18.97%和3.07%,三者加起来解释了全部交互作用的83.01%,而且第一主成分（IPCA1）达到差异极显著水平。AMMI双标图及稳定性参数显示,‘黔薏鉴2号’、‘安紫薏苡’和‘文薏2号’属于高产稳定型品种（系）,可作为推荐品种,‘莆薏6号’产量中等、稳定性最差,‘文薏3号’、‘金沙1号’的丰产性较差,综合稳定性一般;此外,云南昆明、福建莆田、贵州兴义和贵州安顺的试点代表性较强;云南文山、贵州凯里、广西百色和福建福州的地点鉴别力相对较弱。The study aims to investigate the effects of genotype and environment interaction on yield stability and site discrimination of Job＇ s Tears in China, and provide guidance for identifying, recommending and registering excellent cultivars in production scientifically. The combination of double mark figure and special interaction [Dg（e）] of AMMI model was used to identify yield stability and site discrimination of the Job＇ s Tears cultivars, whose data came from the national regional trials of 2012-2014. The results showed that the output of 6 varieties ranged from 2380.0-6061.0 kg/hm2, 1933.3-5790.0 kg/hm2, 2192.0-5632.3 kg/hm2, 905.3-5485.7 kg/hm2, 978.3-4680.0 kg/hm2, 991.0-5340.0 kg/hm2, respectively. There were significant effects of genotype （G）, environment （E） and G x E interaction. The percentage of the sum of squares of genotype, environment and G × E interactive effects on total sum of squares were 8.41%, 55.10% and 14.03%, respectively. IPCA1, IPCA2 and IPCA3 represented the 60.97%, 18.97% and 3.07% of GxE interaction with a total of 83.01%, of which the IPCA1 was at 0.01 significant level. Therefore, ‘Qianyijian3＇, ‘Anziyiyi＇ and ‘Wenyi2＇ had higher and more stable output, which should be recommended. ‘Puyi6＇ had a moderate output,and ‘Wenyi3＇ and‘Jinshal＇ possessed worse stability and a general yield. Moreover, test-sites of Kunming in Yunnan, Putian in Fujian, Xingyi in Guizhou possessed a stronger site discrimination, to the contrary, Wenshan in Yunnan, Kaili in Guizhou and Baise in Guangxi had a relatively lower one.
