Abstract
A new plant was created as an interspecific hybrid of the genus Euphorbia. The plant was created by the rescue of an embryo resulting from the cross-pollination of a cultivated Poinsettia, Euphorbia pulcherrima, with a seedling of the uncultivated Euphorbia cornastra. The new interspecific hybrid plant was found have unique traits that differed from either parent. The plant exhibited colorful flower bracts indicating desirable characteristics for ornamental use. In addition to providing the interspecific hybrid plant and parts thereof, the invention provides methods for making the same as well methods for creating interspecific hybrid plants having altered growth characteristics and the plants created thereby.
Claims25
An interspecific hybrid Euphorbia plant produced from a cross between Euphorbia pulcherrima as a female parent and Euphorbia cornastra as a male parent.
A plant part of an interspecific hybrid Euphorbia plant produced from a cross between Euphorbia pulcherrima as a female parent and Euphorbia cornastra as a male parent.
A process of producing an interspecific hybrid Euphorbia plant comprising crossing a Euphorbia pulcherrima plant with a Euphorbia cornastra plant, rescuing an embryo resulting from the crossing and obtaining an interspecific hybrid Euphorbia plant grown therefrom, wherein the Euphorbia cornastra plant is used as a male parent and wherein the Euphorbia pulcherrima plant is used as a female parent.
A process of preparing an interspecific hybrid Euphorbia plant comprising the steps of:
- a) obtaining a cutting of an interspecific hybrid Euphorbia plant produced from the cross of Euphorbia pulcherrima as a female parent and Euphorbia cornastra as a male parent;
- and
- b) cultivating said cutting to obtain an interspecific hybrid Euphorbia plant.
A process of altering the plant growth characteristics of an interspecific hybrid Euphorbia plants produced from a cross of Euphorbia pulcherrima and Euphorbia cornastra, the process comprising the steps of:
- (a) providing a plant having free-branching characteristics to be used as understock;
- (b) obtaining a scion of an interspecific hybrid Euphorbia plant produced from the cross of Euphorbia pulcherrima as a female parent and Euphorbia cornastra as a male parent;
- (c) making a graft union between the cellular tissue of the understock plant and the scion, whereby the characteristics of a vegetative shoot arising from said scion of said interspecific hybrid Euphorbia plant are altered;
- and
- (d) cultivating said shoot to obtain an interspecific hybrid Euphorbia plant comprising altered growth characteristics.
