The invention provides a method for interspecific hybridization culture of a rose cultivar.A new rose species with excellent characters of parents is generated through hybridization of wild rose and traditional rose.The female parent line A is Rosa gugosa cv.plena, the male parent line B is Rosa multiflora thunb.Var.Albo-plena Yuet Ku, the offspring F1 with the comprehensive characters of the traditional rose line A as well as the target characters of the wild rose line B are cultured and screened through hybridization, F1 is subjected to selfing and purification, the flower color of generated plants is red mostly and white as minority, selfing of plants with white flower color is conducted, and a new generation of white hybridization rose cultivar which can bloom continuously, has both comprehensive characters and target characters and is stable is selected.

The invention relates to an artificial cuttage breeding method of wild Rosa odorata var. gigantea. The method comprises the following steps of: selecting a wild Rosa odorata var. gigantea tree which grows for 3-5 years and has favorable development of a tiller branch of the root and stem part as a female parent material; cutting the lignified or semi-lignified raw branch in the current year, which is the stem and root part and is not budded, as a fringe; selecting the tip part and middle section part of the fringe for manufacturing inserted fringe; carrying out right-angle cutting on an uppernotch in the cutting position, wherein a lower notch is an inserted fringe base notch; carrying out slope cutting and cleaning disinfection on the node and soaking the node in a root growing powder accelerating agent aqueous solution, and then inserting into a seedling bed according to the plant row space of 30cm*10cm; and after growing and budding the inserted fringe, withdrawing a sunshade screen and entering a natural growth phase. The method disclosed by the invention is simple and convenient and has low cost; on one hand, the method provides sufficient raw material guarantee for the production of a pharmaceutical enterprise and realizes the scientific utilization of plant resources; on the other hand, the method protects wild resources and ecological environment and has favorable market application prospect.

The invention provides a method for cultivating a rose cultivar by double hybridization of three cultivars. Double hybridization is performed by three different rosa plants. A series Shandong Rosa gugosa cv. plena serving as a female parent is artificially hybridized with B series Rosa bella Rehd.et wils to obtain an offspring ABF1, the A series Shandong Rosa gugosa cv. plena serving as the female parent is artificially hybridized with C series Rosa davurica Pall to obtain an offspring ACF1. The ABF1 is hybridized with the ACF1, variant plants with flower color, petal count, flowering phase length and drought, cold, salinity and alkalinity resistance obviously improved as compared with parents are screened out, and the offspring of the variant plants is inbred and purified to obtain the stable new-generation hybrid rose cultivar capable of continuously blooming and having comprehensive characters and objective characters.

The invention discloses a rapid identification method of physiological race of Chinese rose powdery mildew bacterium. The rapid identification method comprises the following steps: separating, purifying, and propagating Chinese rose powdery mildew bacteria, preparing spore suspension of Chinese rose powdery mildew bacteria, preparing a Chinese rose host material, inoculating, observing the state of powdery mildew, and carrying out statistics, analysis, and identification. In the step of separation, purification, and propagation, powdery mildew bacteria from wild Chinese rose are transferred to leaves of tissue cultured seedlings of rosa odorata; powdery mildew bacteria from cultivated Chinese rose are transferred to leaves of tissue cultured seedlings of purple Chinese rose; 11 domestic identified host materials are chosen, after the step of separation, purification, and propagation, Chinese rose powdery mildew bacteria to be identified are inoculated on 11 domestic identified host materials, and the physiological race can be identified by comparing the physiological race with a comparison table. The method can identify 11 physiological races of Chinese rose powdery mildew bacterium. Only 7 days are needed from inoculation to identification. The method can be used to guide the breeding of Chinese rose species that is resistant to powdery mildew.

The invention provides rose and lemon honey cake, which is prepared from the following ingredients in parts by weight: 200 to 230 parts of glutinous rice flour, 60 to 70 parts of pineapple powder, 25 to 35 parts of yolk powder, 35 to 40 parts of almonds, 45 to 50 parts of peanuts, 35 to 45 parts of lemon, 25 to 30 parts of dark plums, 60 to 70 parts of yoghourt, 8 to 10 parts of black tea, 10 to 13 parts of rose, 8 to 10 parts of mint, 5 to 7 parts of sepium, 4 to 6 parts of bletilla striata, 4 to 5 parts of radices pseudoginseng, 3 to 5 parts of fructus evodiae, 2 to 3 parts of lycopus lucidus and the like. The rose and lemon honey cake provided by the invention has the advantages that the preparing process achieves environment-friendly and pollution-free effects; the rose and lemon honey cake is processed by adopting natural food materials; fruits such as the lemon and the dark plums are added, so a good oxidation-resistant effect and a good radiation-resistant effect are achieved; through the addition of extracts of the rose, the mint, the sepium, the bletilla striata, the radices pseudoginseng and the like, certain effects of astringency, hemostasis and radiation resistance are achieved; and the rose and lemon honey cake is particularly suitable for people working and studying under the radiation effect for a long time to eat.
