Problems solved by technology

But so far, there are few reports on the interspecific hybridization technology between roses and roses. Researchers have made many attempts, only using traditional pollination hybridization operations to deal with roses and roses, and found that roses and roses have serious differences. Interspecific hybridization barriers seriously affect the breeding process of rose varieties

Embodiment 1-8 and comparative example 1-2

[0032] The cultivation methods of Examples 1-8 and Comparative Examples 1-2 are similar, and the difference is that: the female parent A line rose Serbia is treated differently in the early stage of hybridization. A specific cultivation operation process is given below to illustrate:

[0033] S1: This application establishes an experimental field in Tai'an, Shandong Province, and selects healthy parents that are free from disease and pests. The day before the flowering period of the female parent A series roses in Serbia, strong flower buds are selected for emasculation, covered with sulfuric acid paper bags for isolation, and harvested from different plants. The anthers were collected in different clean sulfuric acid paper bags, marked and brought back to the room, and placed in a ventilated place at 20-25°C to dry in the shade.

[0034] According to the maturity of the stigma of the female parent A-line Serbia, when the stigma secretes mucus, inject a certain amount of treatm...

Embodiment 9-11

[0054] The difference between embodiment 9-11 and embodiment 8 is:

[0055] In step S1, in Example 9, strong flower buds were selected two days before the flowering period of the female parent A series rose in Serbia to emasculate, covered with sulfuric acid paper bags for isolation, and the anthers picked from different plants were collected in different clean sulfuric acid paper bags , mark it and bring it back indoors, and place it in a ventilated place at 20-25°C to dry in the shade;

[0056] In step S1, in Example 10, strong flower buds were selected three days before the flowering period of the female parent A line rose in Serbia to be detasseled, covered with sulfuric acid paper bags for isolation, and the anthers picked from different plants were collected in different clean sulfuric acid paper bags , mark it and bring it back indoors, and place it in a ventilated place at 20-25°C to dry in the shade;

[0057] In step S1, in Example 11, select strong flower buds to de...

Abstract

The invention discloses a method for cultivating roses through interspecific hybridization. The method comprises the following steps: S1, taking a female parent A line as Rosa Salvia and a male parent B line as Rosa rugosa 'Suyu', collecting pollen of the male parent B line, pollinating the pollen on stigmas of the female parent A line for hybridization, and cultivating and screening out the progeny F1 with continuous flowering characters of the female parent A line rosa and comprehensive characters of the male parent B line roses, wherein a treating agent is injected into the concave part of the receptacle before pollination of the female parent A line, and the treating agent is prepared from echinocandin B with the concentration of 0.005 wt% to 0.008 wt% and colchicine with the concentration of 0.01 wt% to 0.07 wt%; S2, performing selfing purification on the F1 to generate a plant F2 (pw) of which the flower color takes white as a main color and pink as an edging and a plant F2 (P) of which the flower color is pink; S3, performing selfing purification on the F2 to obtain pink edged white roses with stable target characters. The rose variety with high resistance and long flowering period is obtained.

Description

technical field [0001] The invention relates to the technical field of rose cultivation, in particular to a method for cultivating roses by interspecific hybridization. Background technique [0002] Rose (Rosa rugosa Thunb.) is a plant of the genus Rosa in the family Rosaceae. It has been planted in my country for more than two thousand years and is an important ornamental shrub. And Rose Suyu (Rosa rugosa'Suyu') has strong adaptability, has the advantages of being resistant to drought and barrenness, cold tolerance, and strong resistance. month or so), affecting its ornamental value. [0003] Rose (Rosa chinensis Jacq.) belongs to the same family as roses, and now mostly refers to modern rose varieties. It is a huge group of four-season flowering varieties formed after long-term artificial breeding. Because of its gorgeous flower color, beautiful flower shape, wide variety and rich variety, it is deeply loved by people, but its narrow genetic background makes many varieti...
