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

[0027] a. Establish an experimental field in Zibo, Shandong Province, select healthy parents without disease and pests, and carry out male parent B line rose glandular leaves (Rosa kokanica Regel ex juz) on the female parent A line Shandong double-petal red rose (rosa gugosa cv.plena) .) of 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 them, select the better plants among them, and carry out artificial pollination by backcrossing with the recurrent parent A line Shandong red rose (rosa gugosa cv.plena) again. Carry out manual daily management after pollination, and collect good seeds. After repeated backcrossing for 7-8 times, a rose plant with ideal flower leaf shape, plant flower yield, fragrance type and resistance was produced, and the rose plant was self-purified again to obtain a new rose variety Zhongtian Rose No. 1 (Topr...

Abstract

The invention provides a method of cultivating rose cultivars through distant backcross. The method comprises the following steps: rosa multiflora with cold resistance, drought resistance and saline-alkaline tolerance and traditional roses are hybridized through research, wherein a female parent A system is Rosa gugosacv. plena, a male parent B system is Rosa kokanica Regel ex juz.; an offspring F1 which has the comprehensive characters of the traditional rose of the female parent A system and the target characters of the rosa multiflora of the male parent B system is obtained by cultivation and screening after the hybridizing; the F1 is backcrossed with a recurrent parent A system for multiple times, the offspring of the F1 is self-crossed for purification, and a new generation stable hybrid rose variety, which has comprehensive characters and target characters and is capable of continuously flowering, is selected and obtained.

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 distant backcrossing. 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 through distant backcrossing. The new roses bred by the method have the advanta...
