Problems solved by technology

[0002] At present, most of the roses planted in my country use traditional roses, which bloom in one season, have relatively poor resistance, single fragrance, low yield, and limited suitable growing areas.
Due to factors such as flower production, essential oil yield, fragrance type and planting scale, the processing industry has not yet formed a complete industrial chain, let alone go abroad to occupy the international market share

specific Embodiment

[0028] a. Set up an experimental field in Zibo, Shandong, select healthy parents without disease and pests, and carry out the male parent B line rose (Rosa webbiana Wall.ex) on the female parent A line Shandong double-petal red rose (rosa gugosa cv.plena) Royle's artificial pollination. Carry out manual daily management after hybridization, and collect good seeds. In the second year, the hybridized seeds F 1 Sow the seeds separately, compare and identify, select the better plants among them, and use it as the female parent to cross artificial pollination with the male parent C line Rosa davurica Pall again. Carry out artificial daily management after pollination, and collect good seeds F 1 C, F 1 C was then purified by selfing to obtain F 2 c. Then adopt the derivation system method to carry out the selection of excellent plants, and obtain a new product rose plant with ideal mosaic leaf shape, plant flower yield, fragrance type and resistance, which is Zhongtian Rose No....

Abstract

The invention provides a composite hybridization and cultivation method of rose variety. The cold resistance, the drought resistance and the saline-alkaline and poor soil resistance of wild roses are high and accordingly the important germplasm for cultivating the new rose variety is achieved. The composite hybridization and cultivation method comprises serving Rosa gugosa cv. plena as a female parent to perform the first hybridization on the Rosa gugosa cv. plena and Rosa webbiana Wall. ex Royle, cultivating and screening out descendants F1 which comprise comprehensive traits of the traditional roses and target traits of the wild roses; performing the second hybridization on the F1 and Rosa davurica Pall and screening out variant plants, wherein the flower color, the number of petals, the flowering duration and the drought resistance, cold resistance and the saline-alkaline resistance of the variant plants are significantly improved in comparison with the parent; performing selfing purification on descendants of the variant plants and selecting out a new generation of stable hybrid rose variety which can continuously bloom and comprises the comprehensive traits and the target traits.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for cultivating rose varieties through compound hybridization. Background technique [0002] At present, most of the roses in my country are planted with traditional roses. Traditional roses bloom in one season, have relatively poor resistance, single fragrance type, low yield, and limited suitable growing areas. Due to factors such as flower production, essential oil yield, fragrance type and planting scale, the processing industry has not yet formed a complete industrial chain, let alone go abroad to occupy international market share. Therefore, developing new product rose is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0003] The object of the present invention is to provide a method for compound hybridization to cultivate rose varieties. The new roses cultivated by the method have the adva...
