Title:
METHOD FOR CREATING NEW RUSSELL PRAIRIE GENTIAN CULTIVAR
Document Type and Number:
WIPO Patent Application WO/2016/052760
Kind Code:
A1
Abstract:
The problem of the present invention is to elucidate the inheritance pattern of Russell prairie gentian, including the genotype of the thus far unknown yellow flower, white flower, double flower, marginal variegation, and splashed pattern traits and further, to provide a method for creating a new Russell prairie gentian cultivar having diverse flower colors and/or flower forms. Provided is a method for creating a new Russell prairie gentian cultivar using a genotype corresponding to the flower color trait and/or flower form trait of Russell prairie gentian, where the genotype is Ans/ans·HxHx·Pg/pg·Cy/cy·Dp/dp consisting of: (a) genotype HxHx (whereHx is the dipole gene represented by HT, HF, HD, HZ, HO or HE) of the dipole gene that controls B ring hydroxylation of the pigment precursor of flavonoid biosynthesis and that participates in synthesis of the main anthocyanidin pigments of Russell prairie gentian, peralgonidin (Pgn), cyanidin (Cyn), or delphinidin (Dpn); (b) genotype Pg/pg·Cy/cy·Dp/dp of peralgonidin (Pgn), cyanidin (Cyn), or delphinidin (Dpn), which is the primary anthocyanidin pigment of Russell prairie gentian; and (c) genotype Ans/ans of colored flower/white flower, or a genotype that is a combination of Ans/ans·HxHx·Pg/pg·Cy/cy·Dp/dp with any one or more selected from genotype YxYx that determines the combination of yellow flowers and white flowers, genotype DxDx that determines the combination of 8-flower, 2-flower, and 1-flower clusters, genotype E/e of marginally variegated petals/solid-colored petals, and genotype B/b of solid-colored petals/splashed-pattern petals.
