Phenotypic Variation in Flower Color and Morphology in the Gerbera (Gerbera hybrida) F₁ Hybrid Population and Their Association with EST-SSR Markers.

ABSTRACT: Gerbera (Gerbera hybrida) is a widely cultivated ornamental plant. However, its genetic improvement is limited by the lack of genetic analysis and molecular markers for traits. In this study, we analyzed the phenotypic and genotypic variation of 140 F₁ progeny from two gerbera varieties with different flower types and colors. We evaluated the flower's morphology, color, and pigment content of the F₁ population and performed cluster principal component analysis (PCA) and correlation analysis. The results showed that the main ornamental traits of the hybrid progeny varied greatly. The segregation ratios of single and double flowers and ligulate and split ray florets were both 1:1. The flower colors of the F₁ progeny were mainly red and purple-red, simi
