Breeding method for cultivating new germplasms of ornamental dwarf-stalk sugarcane

Abstract

The invention belongs to the technical field of sugarcane breeding and particularly relates to a breeding method for cultivating new germplasms of ornamental dwarf-stalk sugarcane. In order to cultivate ornamental sugarcane which is dwarf in stalks, compact in plate type and not prone to defoliation and can be potted on a balcony or indoors, the method comprises the steps of using Badila as a female parent; carrying out distant hybridization on the Badila and a wild Erianthus rockii male parent of Erianthus fulvus to obtain a distant hybrid; selecting a progeny strain with remarkably dwarfed plant height as the female parent; hybridizing with a German sugarcane 93-88 male parent to obtain a noble hybrid; finally, selecting a noble progeny strain with remarkably dwarfed plant height for selfing; and finally, carrying out cultivation to obtain a series of new sugarcane germplasms which are compact in plant type, upright in leaf, emerald green in color, not prone to defoliation, strong intillering, short and small in plant, slow in plant height growth, short and dense in stem node, 80-150 cm in plant height, capable of being planted in fields and potted, and have the functions of beautifying courtyards, decorating the balcony 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.
