PROBLEM TO BE SOLVED: To provide means to create novel intergeneric hybrid plants that can assist in the development of such characteristics as increased capitula diameter, male sterility, female sterility, improved heat tolerance, perpetual flowering, new flower colors and brighter flower colors.SOLUTION: New plants were created from a new and efficient method of intergeneric hybridization between a plant from the group consisting of I. versicolor and Glebionis sp. as a female parent and a plant from the genus Argyranthemum as a male parent. The plants were created by rescuing an embryo from the cross-pollination of a plant from the group consisting of I. versicolor and Glebionis sp. as a female parent with an Argyranthemum male parent. A method for infecting hybrid plants with a virus and a viroid to modify plant phenotype is also described. Intergeneric hybrid plants and self-pollination plants are created by the methods of producing plants.
