Abstract: Heredity of some characters of flower and leaf in F1 individuals of mother(Rosa ‘Yunzheng Xiawei’) and father(R. ‘Sun City’) were measured and analyzed with variance, coefficient of variation, inheritance and correlation. The coefficient of variation in the hybrid population was 7.33%-68.08%, indicating a significant phenotypic variation. Among them, the number of petals in the population showed the highest degree of variation. All the traits measured had high degree of dispersion and came out new phenotypic traits, different from parents. The analysis of the genetic characteristics and correlation of phenotypic traits will benefit for selecting breeding and assisting breeding for dominant genes in controlling phenotypic traits.

Key words: Rosa spp., phenotypic traits, genetic analysis, correlation
