以9个超级早稻品种和1个对照品种为材料，在4个地点分别设置2个施氮水平进行种植，利用AMMI统计模型对其丰产性和稳产性进行了研究。结果表明，不同超级早稻品种的产量受到基因型、环境以及基因型和环境互作的影响，其稳产性主要受基因型控制，受施氮量影响较小，而丰产性除了受种植地点影响外还受施氮量的影响，因此，生产中对水稻品种的丰产性和稳产性评价必须结合种植地点、栽培措施等多因素进行综合分析。通过研究，筛选出了中早39和淦鑫203两个典型的高产稳产型品种。
以9箇超級早稻品種和1箇對照品種為材料，在4箇地點分彆設置2箇施氮水平進行種植，利用AMMI統計模型對其豐產性和穩產性進行瞭研究。結果錶明，不同超級早稻品種的產量受到基因型、環境以及基因型和環境互作的影響，其穩產性主要受基因型控製，受施氮量影響較小，而豐產性除瞭受種植地點影響外還受施氮量的影響，因此，生產中對水稻品種的豐產性和穩產性評價必鬚結閤種植地點、栽培措施等多因素進行綜閤分析。通過研究，篩選齣瞭中早39和淦鑫203兩箇典型的高產穩產型品種。

The productivity and stability of nine super early rice cultivars in Jiangxi Province were studied by AMMI statistic model with four plant places and two nitrogen supply levels.The results showed that the grain yields of different cultivars were affected by the genotype, environment and their interaction;the stability of grain yield was mainly determined by the genotype and was less affected by nitrogen level. However,the pro?ductivity was affected by the environment and the nitrogen level.In order to objectively evaluate the productivity and stability of rice cultivars,a comprehensive analysis of the plant place and cultivating measures should be carried out.By compare experiments,two high-yielding and stable-yielding cultivars of Zhongzao39 and Ganx?in203 were screened out.
