Problems solved by technology

[0004] Because it is difficult to improve the shape of cotton flowers and is easily affected by light and temperature, it is very difficult to fix the variation of cotton flower shapes. Cotton varieties with rose-shaped or windmill-shaped flowers need at least 7 generations to be successfully cultivated, and the breeding time is long
Moreover, during the popularization process, since the genetics of cotton varieties with rose-shaped or windmill-shaped flowers have been stabilized, they can be self-bred and retained, so it is difficult to protect intellectual property rights

Abstract

The invention relates to the field of ornamental plants, in particular to a breeding method for ornamental cotton. The breeding method comprises the following steps: taking a cryptanthous material CJ1548143 as a female parent, taking island cotton variety Xinhai 21 as a male parent, hybridizing and harvesting F1-generation seeds; planting the F1-generation seeds, then selfing and harvesting F2-generation seeds; planting the F2-generation seeds or offspring seeds thereof, and screening to obtain target flower-shaped ornamental cotton; taking the screened ornamental cotton as scions for grafting, and culturing to obtain seedlings of the ornamental cotton. The inventor accidentally discovers that windmill-shaped or rose-shaped or approximately flow-shaped ornamental cotton can be obtained bytaking the cryptanthous material CJ1548143 as the female parent, taking the island cotton variety Xinhai 21 as the male parent, hybridizing, slefing the harvested seeds and then further planting; theornamental cotton is bred by adopting a grafting mode, and ornamental cotton plants can be quickly produced on a large batch, so that the demands of a cotton ornamental market are met.

Description

technical field [0001] The invention relates to the field of ornamental plant cultivation, in particular to a method for propagating ornamental cotton. Background technique [0002] In plant taxonomy, cotton belongs to Plantae, Angiospermae, Dicotyledoneae, Malvales, Malvaceae, and Gossypium. my country has a long history of cotton planting. As one of the main economic crops, cotton is harvested as natural fiber and used in the textile industry. [0003] In recent years, with the improvement of living standards, people's pursuit of beauty has become higher and higher, and they have begun to plant a large number of ornamental plants at home to cultivate their sentiments and improve their living environment. Cotton has unlimited growth habits, suitable environmental conditions, can grow for many years, and has a long flowering period. In addition, cotton bolls are also considered as a kind of flower after flowering, so cotton has also begun to be planted as an ornamental plan...
