Embodiment Construction

[0023] In order to overcome the problem that the crossing between forage triticale and forage rye distant hybridization is difficult to succeed due to lack of flowering period, the present invention provides a method for adjusting forage triticale and forage rye distant hybridization for flowering failure. For the first time, the flowering period of forage rye is delayed by timely mowing, which is basically consistent with the flowering period of forage triticale. The present invention will be further described in conjunction with specific examples below.

[0024] From October 2012 to June 2014, we arranged forage rye cutting experiments at the Hebei Provincial Academy of Agricultural Sciences Dry Farming Water Saving Experimental Station for two consecutive years. Taking forage triticale and fodder rye without mowing as controls, a total of 7 experimental treatments were carried out, each treatment was planted with a plot, the area of ​​the plot was 2m×3m, the row spacing was ...

Abstract

The invention discloses a method for adjusting asynchronous flowering of forage triticosecale wittmack and forage rye in distant hybridization. The forage triticosecale wittmack and the forage eye are selected as hybrid parents for distant hybridization, the forage triticosecale wittmack is used as a male parent, the forage rye is used as a female parent, the forage rye is cut before the forage rye is in a booting stage, and the method is used for ensuring that the forage triticosecale wittmack and the forage rye have synchronous flowering. The problem that the forage triticosecale wittmack and the forage rye have asynchronous flowering in distant hybridization is solved, and convenient conditions are provided for richening the species genetic basis of the forage triticosecale wittmack through external source genetic genes.

Description

technical field [0001] The invention belongs to the technical field of breeding triticale varieties for feeding, and in particular relates to a method for adjusting the flowering period of distant hybrids of triticale and rye. Background technique [0002] Distant hybridization is of great significance in the field of breeding. By using distant hybridization, biological evolution and kinship can be studied, and the law of species development can be proved; by using distant hybridization, new species can be created, such as triticale; by using distant hybridization, you can use Exogenous genetic material enriches the genetic basis of species. However, there are also some problems that are not easy to solve in distant hybridization: first, the hybridization is not easy to succeed; second, the hybrids are not easy to survive and appear sterile; The growth period of the two species of distant hybridization is quite different, and the gametes of both sides are separated in time,...
