METHOD OF CROSSING FLOWER COLOR GENOTYPES

摘要

It is intended to clarify heredity of the biosynthesis of flower pigments and the relationship between flower color heredities and pigment genotypes, thereby providing a method of crossing flower color genotypes which is practically available in creating a novel flower color. There is found out a novel rule that flower color genotypes relate to the biosynthesis of flavonoids represented by the pathway (I) and the heredities of flavonoid 3'-hydroxylase (F3'H) and flavonoid 3',5'-hydroxylase (F3',5'H) are controlled by 5 multiple alleles. As a result, it becomes possible to provide a method of producing a novel flower color with the use of genotypes D/d.E/e.H<X>H<X>.Pg/pg.Cy/cy.Dp/dp by which flower colors can be freely created based on flower pigment genotypes without resort to gene recombination or mutation caused by exposure to radiation, etc.
