摘　　要：对15个玫瑰品种进行了产量性状的遗传相关和通径分析。相关分析结果表明,单株花蕾数、分枝数、花瓣数与产量呈极显著相关;通径分析结果表明,单株花蕾数、分枝数和单个花蕾鲜样质量对产量形成的直接作用最大,这3个性状对产量的决定系数总和达0.920 5,可以作为玫瑰育种的主要选择性状。This research aimed to study the genetic correlation and path analysis of 15 kinds of Rosa rugosa yield traits. The results of correlation analysis revealed that a very significant positive correlation was found between the yield and the number of floral bud per plant, the number of branches and petals. The results of path analysis showed that the yield was affected mostly by three traits, i： e. the number of floral bud per plant, the number of branches and the fresh mass of pedals per floral bud. Therefore, the determination coefficient of these three characters to yield amounts to 0. 920 5, and they could be taken as main selection characters for high yield of Rosa rugosa.
