A kind of edible rose and its breeding method
Technical field
The present invention relates to technical field of plant cultivation more particularly to a kind of edible rose and its breeding methods.
Background technology
Rose, alias are hovered flower, the rose family, belong to fallen leaves bush, and China's rose cultivation technique has more than 1300 years
History, there is plantation in existing Korea, Japan, Russia, Europe.It can be for the ornamental and precious Chinese medicine of people, and changes
The fragrance source of chemical product and the important addition raw material of food industry, while also having the function of mountain area greening, water and soil conservation.With
The deep processed product of rose has continuously emerged in the raising for scientific and technological level.Fresh flower can extract attar of rose, brew cider,
Rose medicinal extract, bud can be used as medicine, make health products, can also cuisines dish processed.The ground such as Beijing, Shanghai, Guangdong, Fujian, which are in fashion, to be drunk
Various dried flower tea, rose dried flower flower bud are one kind critically important in dried flower, are widely used in various advanced teahouses, bar, are rich in
The flowers and fruits of natural Vc, are applied to beverage, cigarette, tealeaves, cosmetics.In addition, its value of the attar of rose through refinement is higher than golden number
Times.Rose and its deep processed product are the important source materials of the expensive essence and flavoring agent of manufacture.Essence and flavoring agent industry and people's living standard
Raising it is closely related, in terms of world wide, the growth rate of essence and flavoring agent industry in recent years is flat always above other industry
Equal speed.The international fragrance industry nineteen ninety output value is 5,100,000,000 dollars, reaches within 2000 10000000000 dollars, reaches within 2002 16600000000 U.S.s
Member reaches 18,400,000,000 dollars for 2004, reaches 35,000,000,000 dollars within 2013.Demand cumulative year after year of the domestic market to essence and flavoring agent,
Shared manufacturing enterprise 450 in 1994,8,400,000,000 yuan of the gross output value, by 2000, manufacturing enterprise up to 600, the output value up to 15,000,000,000 yuan,
By 2013, manufacturing enterprise reached 750, and the output value is close to 30,000,000,000.As the improvement of people's living standards, perfume industry also exists
It will keep the development trend of high speed for quite a long time from now on, also year by year to the demand of rose and its deep processed product
Increase.
China has a long history in the cultivation of rose, use aspects, but industrialized development is started late, industrialization
Level differs greatly with foreign countries.The rose of western China is cultivated mainly based on the misery town of Gansu Province Yongdeng County, rare cultivation
History has reached nearly 200 years time, at home and abroad wins a high admiration, but since varieties of plant aging causes without update
Industry development is slow.Itself main reason is that:First, edible rose researches and develops professional technician scarcity, varieties of plant long-term
Without update, now plant rose variety and seriously degenerate, yield and external mainstream kind " Damascus " occurred compared with
Big gap.Existing 250-300 kilograms of rose variety per mu yield fresh flower, " Damascus " yield is at 500 kgs/acre.Second, existing rose
The rare kind florescence excessively concentrates storage of high cost, and storage can cause main component loss to influence product quality.Third, existing rose
Rare kind fragrance is excessively strong not to be welcome by international market.4th, China western part is vast in territory, illumination is sufficient, well-ventilated, is
Rose cultivates comparatively ideal region, but since the region winter temperature is low and the existing kind of soil meta-alkalescence is difficult to normal growth,
Limit rose scale industrialized development.
In addition, Gansu Province's ecology fragility, Hexi prefecture faces the serious challenge of desertification, and being badly in need of one can be in desert edge
Growth and the new variety of plant resource with Development volue develop to form an industry with huge drive in desert edge
Chain checks winds and fixes drifting sand and improves the ecological environment for western China and play to build up one of green Great Wall in desert edge
Important function.
Therefore it provides a kind of high yield and the edible rose suitable for being planted in China North China, the dry regional culture in Midwest
The technical issues of rare kind is those skilled in the art's urgent need to resolve.
Invention content
In order to solve technical problem present in background technology, the present invention proposes a kind of edible rose, yield it is high and
Suitable in China North China, the dry regional culture plantation in Midwest.
A kind of edible rose breeding method proposed by the present invention, includes the following steps:
S1:The strong edible rose kind of resistance and high yield edible rose mixing breed is selected to obtain edible rose elite plant
System;
S2:The edible rose elite plant strain obtained in S1 is subjected to secondary stem apex detoxification tissue cultures, is adopted again later
Handled with polyethylene glycol stress, induce drought resisting strain, for height drought resisting elite plant strain on alkaline medium after being commissioned to train
It supports, for the tissue-cultured seedling of acquisition, moves into greenhouse and carry out tentatively mirror choosing, obtain elite plant strain and move into field progress systematic breeding, expand
Big breeding edible rose explant simultaneously carries out strain comparison by main economic SHAPE DETECTION, is detected and is tied according to above-mentioned economic character
Fruit obtains edible rose improved seeds;
S3:After the edible rose improved seeds obtained in S2 are screened by variety test and pilot production,
New lines regional test is carried out, edible rose new varieties are obtained.
Preferably, in step sl, use planting area kind as the strong edible rose kind of resistance for parent with it is non-
Planting area high yield edible rose kind is hybridized.
Preferably, in step s 2, when tissue cultures, mutagenesis examination is added in the medium in the tissue cultures starting stage
Agent.
Preferably, in step s 2, variant is tied up under isolated culture condition, is handled by resistance, acquisition high yield,
The strong plant of resistance carries out asexual propagation.
Preferably, in step s 2, it in tissue culture procedures, is first then used successively using stem section alternating temperature detoxification treatment
Meta-alkalescence solid medium, alkaline medium containing hormone, high sugared solid medium, high salt culture medium are cultivated.
The invention also provides the edible rose that above-mentioned edible rose breeding method obtains, plant height 1.8-2m or so, branches
Item is sturdy, and stem is grown thickly, and stem has thick thorn, autumn stem to become red, imparipinnate leaf alternate, 7-9 pieces of leaflet, ellipse
Extremely oval, there is sawtooth at apex point, edge, and chill mark is deep, and the back side has bloom, and net vein is apparent, villous and gland point;Total leaf
Handle villous and seta;Stipule and common petiole symphysis, blade are tipping up.
Preferably, flower pure white, 23-40, petal, pistil is light yellow;Flowers are born in an end, and fragrance is dense, more dry stronger;
6.5-9 centimetres of single flower crown diameter, 2.5-3.5 centimetres or so of bud are red, the month at florescence 5-9 when bud is not opened.
Preferably, oil content is in 0.08%-0.10%.
The edible rose that edible rose breeding method proposed in the present invention is cultivated, high yield, yield is in 500-650 public affairs
Pound/acre;Slightly above Damascus;Florescence was long and disperses, up to 150 days or so;Odor type and international mainstream kind " Damascus "
Close but more containing, bottom note is thick and heavy;Resistance is strong, can be grown under alkalinity, drought condition in 900-2000 meters of altitude ranges,
It can normal cultivating and growing in desert edge area.
