Problems solved by technology

Long-term artificial cultivation and selection have made Celosia a crown-shaped inflorescence, obvious main stem, few branches, long and wide leaves, etc., which are suitable for viewing. However, the plants lacking green beetles are taller, have many branches, and narrow leaves. and other features

Embodiment 1

[0020] Embodiment 1: the selection and breeding of Qianhuohong

[0021] a. Selection of distant parents and hybridization and hormone treatment

[0022] The red cultivated cockscomb was used as the female parent, and Qingyi No. 1 was used as the male parent. The red cockscomb has a plant height of 60cm-75cm, a single red corolla, red leaves, and light red stems; Qingyi No. 1 has a plant height of 138cm-170cm, multi-branched, scattered spikes, the tip of the inflorescence is lavender, and the leaves are green. Stem green.

[0023] From late July to mid-September in Wuhan, from 6:00 to 9:00 in the morning, thinning and emasculation of red cockscomb flowers were carried out, and covered with paper bags; from 10:30 to 12:00, take Qingyi No. 1 with tweezers Put the anthers in a small petri dish, use a clean brush to stick pollen on the emasculated stigma of red cockscomb, use 4 to 5 pollen of No. 1 Qingli for each flower, and then bag it. From 4:30 to 6:30 in the afternoon of t...

Embodiment 2

[0030] Example 2: Breeding of "Hongtalin"

[0031] Procedures a~b are the same as the breeding of Qianshuihong. The traits selected in the process c are focused on the characteristics of the red multi-branched lighthouse type. After 9 generations of self-selection, a new line (species) of celosia with a plant height of 90cm~110cm, multi-branched, red leaves and stems, each branch gathered into a tower-shaped inflorescence was formed stably, named "Hongtalin" .

Abstract

The invention provides a method for breeding cockscomb new variety with new variety characteristics and diseases resistance, and the method is realized by utilizing a distant hybridization and back cross breeding technology of culturing cockscomb and feather cockscomb. The technical scheme of the method is as follows: a, selecting a distant parent to perform hybridization and hormone treatment; b, selecting a hybrid to perform back cross breeding with the other culture variety; c, selecting hybrid progeny; and d, stabilizing a finished product variety (system). The method has the following advantages that 1, excellent characteristics of wild feather cockscomb are hybridized to the new variety to form a poly-spike new variety, namely poly-spike red cockscomb; 2, new characteristics combining the cockscomb and the feather cockscomb are generated, such as red tower cockscomb, yellow tower cockscomb, red torch cockscomb and short multi-crown cockscomb; and 3, the new variety (system) has new ornamental characteristics, and has the characteristic of stronger disease resistance.

Description

Technical field [0001] The present invention involves a method of using far -fate hybridization and recovery technology to select new varieties of cocks, which belongs to the technical field of flower breeding of modern agriculture. Background technique [0002] In the process of cultivating excellent varieties, due to the easier success of the varieties in species, breeders have always used the genetic resources of cultivation species (Pan Jiaju, 1994, general theory of crop breeding, 129-148).Now I have felt that the genetic resources in the cultivation species are poor, and some characteristics and characteristics are difficult to find in the cultivation varieties, and wild species generally retain and accumulate these characteristics and characteristics under the harsh survival competition and natural conditions.Therefore, by cultivating the excellent genetic resources that have been domesticated and a large number of unlaticized species that have been domesticated and a larg...
