| 摘 要： | 对家蚕品种最适环境片区划分进行了研究，初步得到如下结果：参试的8个地区可以划分为两个环境片区。第一个环境片区包括四川、重庆和浙江；第二个环境片区包括陕西、山东、安徽、湖北和镇江；第一个环境片区的最适基因型是品种B；第二个环境片区的最适基因型是品种C。如果在各环境片区推广相应最适基因型比在所有地区只推广品种C，则全区平均万蚕收茧量可提高2．1％。

| Abstract: | The objective of this study is to apply AMMI model to mega-environment analysisfor silkworm genotypes. Based on the results,the eight areas tested were classified into 2mega-environments. The first mega-environment included Sichuan (SC),Chongqing (CQ)and Zhejiang (CJ), and the second mega-environment included Shaanxi (SX), Shandong(SD),Anhui (AH),Hubei (HB) and Zhenjiang(ZJ). The variety B wins in the first megaenvironment,the variety C wins in the second mega-environment. By rcaing the varietyof the most suitable genotype in the corresponding mega-environment,the cocoon yieldof 10000 larvae would be increased by 2. 1 percent. |
