Abstract
The purpose of the present invention is to provide a breeding method for a plant having a blue flower color with a simpler blue color development controlling technique, without requiring complex mechanisms for blue color development that have been previously presented and techniques reproducing such mechanisms. Delphinidin-based anthocyanins, in which the both 3′ and 5′-positions of the anthocyanin B-ring have been glycosylated, and flavone glycosides or flavonol glycosides as copigment are made to coexist in the cells of flower organ such as petals.
Claims28
A method of creating a plant with a blue flower color, comprising making delphinidin-based anthocyanins having glycosyl-residues at both the 3′- and 5′-positions of the anthocyanin B-ring coexist with a flavone glycoside or flavonol glycoside in plant cells.
A plant with a blue flower color wherein delphinidin-based anthocyanins having glycosyl groups at both the 3′- and 5′-positions of the anthocyanin B-ring coexists with a copigment (flavone glycoside or flavonol glycoside) in the plant cells, or its inbred or outbred progeny.
