Screening method and application of azalea hybrid offspring flower phenotype excellent single plants

The invention provides a method for screening single plants with excellent flower phenotypes of hybrid offspring of rhododendron. The method comprises the following steps: S1, variety collection: hybridizing rhododendron to obtain hybrid offspring; s2, data collection: collecting morphological data of to-be-screened azalea, and respectively determining quantitative traits and quality traits of each hybrid offspring of the azalea; and S3, calculation: calculating the variation coefficient of the quality character and the quantitative character according to the following formula: screening out the single plants with higher Cv values to finish screening. The invention provides the accurate, rapid and efficient digital screening method for the single plants with excellent flower phenotypes of the rhododendron hybridized offspring, fills the vacancy of the screening technology of the flower hybridized offspring of horticultural plants including rhododendron, and has important application value in the fields of new
