Abstract

The invention relates to the field of ornamental plant cultivation, in particular to a method for cultivating ornamental cotton. The method comprises the following steps that with a cryptanthous material CJ1548143 as a female parent and an island cotton variety Xinhai 21 as a male parent, hybridization is conducted to harvest F1 generation seeds; the F1 generation seeds are planted and selfed to harvest F2 generation seeds; the F2 generation seeds are planted and screened to obtain the ornamental cotton in a target flower shape. It is unexpectedly discovered by the inventor that with the cryptanthous material CJ1548143 as the female parent and the island cotton variety Xinhai 21 as the male parent, hybridization is conducted, the harvested seeds are selfed and then further planted to obtain the ornamental cotton in a windmill shape or a rose shape or an approximate flower shape, and the market demands for the ornamental cotton are met.

Description

technical field [0001] The invention relates to the field of ornamental plant cultivation, in particular to a method for cultivating 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...
