摘要:
应用AMMI模型分析方法对福建省2008~2011年连续4年甜玉米区域试验数据进行产量相关性状分析,结果表明:以基因型效应为主的有株高、穗位高、穗长、穗行数,以环境效应为主的有产量、出苗至采收日数、穗粗,以基因型与环境互作效应为主的有行粒数、鲜百粒重;性状的稳定性以穗长、穗粗、穗行数最好,其次为出苗至采收日数、行粒数、鲜百粒重,第三为株高、穗位高,最差为产量;不同性状在不同生态条件下表现出不同的基因型与环境互作效应。

Abstract:
The yield-correlated characters of sweet corn were analyzed by AMMI model analyzing method based on the regional trial data of sweet corn in 2008-2011 in Fujian. The results showed that plant height, height of ear location, ear length and rows per ear were determined by genotype effect, and the yield, days from emergence to harvesting, ear thickness were determined by environment effect, and grain number per row and fresh weight of 100 grains were determined by genotype譭nvironment interaction effect. As the traits stability, the best were ear length, ear thickness and rows per ear, and the secondly were days from emergence to harvesting, grain number per row and fresh weight of 100 grains, and the thirdly were plant height, height of ear location, the poorest was yield. And different traits showed different genotype譭nvironment interaction effect under different ecological condition.
