AMMI模型应用于桤木种源区域试验的分析研究

Analysis and Research of AMMI Model for Alder Provenances Regional Trails

对桤木 1 3个种源在 5个测试点进行了生长性状的遗传测定。AMMI(加性主效应和复合交互效应 )模型和传统稳定性分析模型相比较 ,AMMI分析和生态价法的结果很吻合 ,而与回归分析法的结果有所差异 ,但排序结果基本是一致的。AMMI的Di 值法相对比较精确可靠。桤木树高在种源间差异极显著。树高相对稳定的种源是四川泸定沙湾、四川雅安和四川金堂淮口 。

The response of 13 alder (Alnus cremastogyne) provenances was evaluated for height at 5 test locations. The genetic stability and adaptability of provenances have been evaluated by using Eberhart's trait regression parameters (b_i and S^2_(di)), Wricke's ecovalue parameter (W_i), the D_i parameter of additive main effects and multiplicative interaction analysis (AMMI). The estimates of AMMI are greatly concordant with the estimates of ecovalue. The methods of AMMI model is comparatively scientific and efficient. It proved that there was a highly significant difference among provenance in height. The stability of provenances including Shawan, Luding, Yaan and Huaikou, Jingtang in height was the highest. The stability of provenances including Changle, Jingtang, Muchuan in height was also the lowest.
