Problems solved by technology

Distant hybridization can create more abundant variation, and it is hoped to obtain more exotic and novel hybrid offspring than intraspecific (inter-species) hybridization, but due to the distant relationship, it is difficult to succeed in many cases

Embodiment 1

[0029] The cultivation and domestication technology of the hybrid new variety of violet flower tree described in the present embodiment mainly comprises the following steps:

[0030] First, the tall deciduous tree Jacaranda mimosifolia (common Jacaranda) and Jacaranda cuspidifolia (beautiful Jacaranda) in Argentina were selected for the first inter-type hybridization. After the first inter-type hybrid tree species was obtained, the hybrid tree species After the second intertype hybridization with Jacaranda chelonia (Chalong blue jacaranda), a stable hybrid tree species is obtained, and then the stable hybrid tree species is backcrossed with Jacaranda chelonia, and after the F1 generation, the male parent jacaranda tree species is obtained;

[0031] Second, based on the fact that the flower color and quality of woody flowers are determined by the content of the pigment characteristic substances in the buds controlled by their genes, the South African Danbia wood Dombeya Rotundif...

Embodiment 2

[0037] The cultivation and domestication technology of the new violet flower tree hybrid variety described in this embodiment are basically the same as in Example 1, the difference is that the content of the pigment characteristic substance in the bud is controlled to be 0.9265 μ p, and the resulting violet flower tree hybrid new variety is as follows: image 3 As shown, the cultivated and domesticated violet flower tree hybrid new variety has good flowering traits, a large number of flowers, good quality, light purple and light blue color, very beautiful and spectacular.

Abstract

The invention discloses a cultivation and acclimatization technology of new gillyflower tree hybridization species, mainly comprising the following steps: common jacaranda, indigo jacaranda and Charoen jacaranda are hybridized among types, the hybridized hybridization tree species is in backcross with the Charoen jacaranda, and a male parent jacaranda tree seedling is obtained after F1 generation; South Africa wurmbaeoideae and South Africa specialty gillyflower tree perform with distant hybridization, and the hybridized hybridization tree species is in backcross with the gillyflower tree; after F1 generation, the growing blade tip meristematic tissue, with favourable growth traits, of the gillyflower tree plant which does not restore sexual variation to form layers in the genetic gene vibration; tissue culture vitro is carried out to form whole favourable tree seedling, and then field cultivation is carried out to obtain female parent gillyflower tree species; the female parent gillyflower tree species is hybridized with the male parent jacaranda tree species, the pigment characteristic substance in a bud is controlled to be 0.0001 mu p-1 mu p to obtain the gillyflower tree. The gillyflower tree is as high as jacaranda and blooms and as gorgeously as cherry blossom trees, the amount of flowers is more than that of a cherry blossom tree, and flower has good quality and has thecolor of violet.

Description

technical field [0001] The invention belongs to garden woody flower breeding and cultivation technology, and in particular relates to a cultivation and domestication technology of a new hybrid variety of violet flower tree. technical background [0002] Cross-breeding refers to a breeding method in which hybrid offspring are obtained through sexual crossing between two genetically different individuals, and then a new variety is bred through selection among the hybrid offspring. Hybrid breeding is an important means of creating new varieties or types of flowers. It can not only combine the excellent characteristics and characteristics of two or more species and varieties, but also produce huge heterosis, improve the growth advantage of flowers, Stress resistance, etc., and sometimes through hybridization, a certain excellent trait of the wild type can be transferred to the cultivated variety. For example, the hybridization of wild orchids will continue to produce new evil or...
