Abstract: 【OBJECTIVE】The flower yield/plant of 13 Rugosa Roses during 2 years was analyzed【METHOD】by AMMI model. The article discussed the interactive effects of genotype and environment on flower yield/plant. 【RESULTS】The results showed that environment made significant influence on each quantitative trait. There were infinitely significant distinct in flower yield/plant on different cultivars.【CONCLUSION】The cultivars of high and stable flower yield/plant was R. rugosa ‘Xizi’, R. rugosa ‘Zifurong’ and R. rugosa ‘Saixizi'. The cultivars of relative stability flower yield/plant was R. rugosa ‘Jade Plate’, R. rugosa‘Tang Pink’, R. rugosa ‘Purple Branch’, R. rugosa ‘Purple Cloud’, R. rugosa ‘Purple Goose’ and R. rugosa ‘Zhuzishuanghui’. The high and unstable cultivars were R. rugosa ‘Tang Purple’ and R. rugosa ‘Puce Dragon’. The lower and unstable cultivars were R. rugosa ‘Tang Red’ and R. rugosa ‘Xiangciguo’.
