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

[0026] a. Set up an experimental field in Zibo, Shandong, select healthy parents without disease and pests, and carry out the male parent B line Baiyutang rose (Rosa multiflora Thunb.Var) on the female parent A line Shandong double-petal red rose (rosa gugosa cv.plena) .Albo-plena Yü et Ku) artificial pollination. Carry out artificial daily management after hybridization, and collect good seed F 1 . In the second year, the hybridized seeds F 1 Sow seeds separately, compare and identify them, select better plants among them for selfing, and perform manual daily management after selfing, and most of the plants produced are red in color. 2(R) , a few suits are white F 2(w) , collect the plants F with white flower color 2(w) Seed. Cultivate white roses in the coming year F 2(w) , and then F again 2(w) Selfing.

Abstract

The invention discloses a method for cultivating a rose variety through interspecific hybridization. Wild rose is hybridized with traditional rose to generate a novel rose variety with good parent character. The female parent A is Rosa gugosa cv.plena, the male parent B is Rosa multiflora Thunb. Var. Albo-plena Yuet Ku, an offspring F1 with comprehensive characters of A series traditional rose and target characters of B series wild rose is obtained through hybridizing, cultivating and screening, F1 performs selfing purification, most of the plants grow red flowers, a few of plants grow white flowers, the plant with white flowers performs selfing, and the new generation of stable hybridized rose variety capable of flowering continuously and having comprehensive characters and target characters is selected.

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 interspecific 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 cultivating rose varieties by interspecific hybridization. The new roses bred by the method have th...
