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.
