A breeding method for cultivating new germplasm of ornamental dwarf sugarcane

Abstract

The invention belongs to the technical field of sugarcane breeding, and in particular relates to a breeding method for cultivating a new germplasm of ornamental dwarf sugarcane, which aims at cultivating ornamental sugarcane with dwarf stalks, compact plant type, and not easy to defoliate, which can be potted on balconies or indoors. Taking Valdella as the female parent, a distant hybrid was obtained by distant hybridization with the male parent of the wild species of Saccharomyces spp. The male parent is crossed to obtain noble hybrids, and finally the noble descendant lines with significantly dwarfed plant height are selected for self-crossing, and finally a series of plants with compact plant shape, upright leaves, emerald green color, not easy to defoliate, and strong tillers are cultivated Dwarf, slow-growing plant height, short and dense stem nodes, plant height 80cm-150cm, can be planted in the ground, potted, and has the function of beautifying courtyards, decorating balconies, and greening vegetation.

Description

technical field [0001] The invention belongs to the technical field of sugarcane breeding, in particular to a breeding method for cultivating new germplasm of ornamental dwarf sugarcane. Background technique [0002] Ornamental plants refer to plants specially cultivated for ornamental purposes, including small foliage and flower viewing plants. With the improvement of people's living standards, the demand for ornamental plants is increasing day by day, and many novel ornamental plants have appeared, such as ornamental vegetables, ornamental sweet potatoes, ornamental fruit trees, ornamental rapeseed, etc., which have greatly stimulated people's interests. Become the most potential part of the flower industry. [0003] Sugarcane (Saccharum officinarum) is an annual or perennial tropical and subtropical herb plant, belonging to C4 crops, with cylindrical stems erect, tillering, clustered, with nodes, with buds on nodes, solid internodes, wax powder on the outside, purple , ...

AI Technical Summary

Problems solved by technology

In recent years, garden sugarcane has been favored by some families, but sugarcane grows too fast, the leaves are easy to fall off, the plant height is too high and needs to be fixed in the later stage, it is not easy to manage, and it takes up a lot of space, etc., which restricts the industrial development of sugarcane as an ornamental plant.
