Abstract :Tulip (Tulipa spp.), belonging to the Liliaceae family, is a bulbous ornamental plant with approximately 280 natural species and 4000 varieties. The aim of this study was to select the most promising genotypes of different tulip (Tulipa spp.) species grown in Turkey with the objective of selection breeding and developing homogenous pure lines of these tulip genotypes (suitable for use as park and landscape plants, possessing traits like large flower, thick stem, long flower life, etc.). The study consisted of 74 tulip genotypes belonging to different Tulipa species. The weighted ranking method was used to select superior tulip genotypes with pedigree selection breeding. Local genotypes scored between 380 and 865 points according to the weighted ranking methods. In addition, tulip genotypes were grouped into classes based on the selection criteria, and the classes and distribution frequencies of tulip genotypes were identified. The top 10 most promising tulip genotypes were selected for evaluation in the variety breeding program. The first three highest-scoring genotypes were G2 (865 point), G3 (790 point), and G1 (785 point) of T. agenensis species, respectively.Keywords : Tulip, genetic resources, selection, frequency distribution, diversity, weighted ranking methods
