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。

Abstract: 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×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 G?E 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,
