Description

Molecular labeling primer and application for the U.S. cultivar identification of Kiwi berry gold
Technical field
The invention belongs to molecular biology and Biotechnology in Genetic Breeding field, it is more particularly to for the U.S. kind mirror of Kiwi berry gold Fixed molecular labeling primer and application.
Background technique
China is the source area of actinidia and the original centre of origin of Kiwi berry genetic resources.In recent years, China Kiwi berry industry expands steadily, and by 2017, national cultivated area 2,900,000 tons of yield, occupied first place in the world up to 2,400,000 mu. In kind pattern, China is studied based on native country Kiwi berry genetic resources, and it is new to have selected the Kiwi berrys such as ' Jin Yan ', ' east is red ' Kind, cultivation extensively, revolutionizes the single pattern of world's Kiwi berry industry only ' Hayward ' kind in the world, pushes The diversification of Kiwi berry market diversification and consumption.
With the increasingly release of Kiwi berry new varieties, the identification of new varieties is a great problem urgently to be resolved.Currently, to Mi The identification of monkey peach patent kind only passes through the traditional means such as tree vigo(u)r, leaf morphology, florescence, floral shape, fruit appearance, inevitably by The influence of environment and other human factors.To the uncertainty of Kiwifruit Cultivars, the healthy and sustainable development of industry, and seedling are limited The wooden kind is impure or even wrong orchard worker's economic benefit will be caused to be badly damaged.
Molecular marking technique can quickly, it is accurate, efficiently kind is identified, to guaranteeing the correct of kind in agricultural production Property has great importance.The suitable molecular labeling of selection and its mating detection technique, establish it is a set of easy, economical, accurate and Efficient cultivar identification and fingerprint pattern technology system, be hit fake and forged seedling, protection plant genetics and breeding worker and The legitimate rights and interests of peasant, specification China agricultural, commodities market there is an urgent need to.
The variation that molecular marking technique is generated in the genome by detecting bion, to carry out area to Different Individual Point, it is the ideal genetic marker of one kind of development after morphological markers and biochemical marker.It is identified in plant germplasm resource And in breeding, reach its maturity to the application of molecular labeling.SSR molecular marker quantity is abundant and is uniformly distributed in gene at random Group is in codominance, and allelic variation is high, and easy to operate and stability is good, has been applied to the cultivar identifications sides such as soybean, apple and grape Face.In Kiwi berry, it has been multiple excellent Kiwi berry product that molecular marking technique is applied to the identification of Kiwi berry male series of products Kind is accurate to provide pollination staminiferous plant, promotes the breeding efficiency of Kiwi berry.
' Jin Mei ' kiwifruit fruit is oval, 60-80 grams of mean fruit weight, close by yellowish-brown bristle, in storage easily It falls off.Pulp yellow or yellow green, the dense sweet tea of flavor, the tender succulence of matter, soft ripe fruit are averaged soluble solid 20%-25%, always Sugar 15%, total acid 1.2%, Vitamin C content 115-158mg/100g fresh fruit meat.Acquisition Ministry of Agriculture New species right in plant in 2018 Certificate.The Molecular Identification that exploitation is suitable for Kiwi berry ' Jin Mei ' kind marks, and is conducive to clearly define patent from molecular level Kind carries out identification and kind protection conducive to Kiwifruit Cultivars.
Summary of the invention
It is an object of the invention to utilize molecular marking technique, a kind of point for Kiwi berry ' Jin Mei ' cultivar identification is provided Sub- labeled primer, the molecular labeling are named as Geo13-84, and the primer for its design is Geo13-84-F: TGAACGAAAGTGGTGCTTTG and Geo13-84-R:AGCCTTCATCGTCTCCTGAA.
It is another object of the present invention to provide the molecular labeling primers for being used for Kiwi berry ' Jin Mei ' cultivar identification to exist Application in Kiwi berry breeding.
In order to achieve the above object, the present invention takes following technical measures:
The acquisition of molecular labeling primer for Kiwi berry ' Jin Mei ' cultivar identification: applicant is from Kiwi berry genome sequence Download ' Red Male ' Kiwi berry complete genome sequence in website (http://bioinfo.bti.cornell.edu/kiwi).Pass through SSR Finder software developing SSR within the scope of full-length genome marks, and is annotated according to gene structure as a result, selecting gene loci design SSR label primer.Using the primer of design synthesis, PCR amplification is carried out to Kiwi berry ' Jin Mei ' kind, screening obtains molecular labeling Geo13-84, the primer for its design is Geo13-84-F:TGAACGAAAGTGGTGCTTTG and Geo13-84-R: AGCCTTCATCGTCTCCTGAA。
Application of the molecular labeling primer in Kiwi berry breeding for Kiwi berry ' Jin Mei ' cultivar identification, including the use of this The primer of invention be used for Kiwi berry breeding, or using primer pair Kiwifruit Cultivars of the invention, especially ' Jin Mei ' kind into Row identification, or include: ' Bu Lunuo ', ' emerald ', ' your length ', ' China to different cultivars according to the size and number of different bands Light 2 ', ' Jin Kui ', ' peasants who dig gold ', ' Jin Xia ', ' Jin Yan ', ' gold and jade ', ' gold circle ', ' chief is close ', ' Longshan is red ', ' MBR ', ' rice good 1 Number ', ' mill mountain 4 ', ' Qingyuan Qiu Cui ', ' No. WH-1 ', ' Hunan fiber crops No. 6 ', ' selecting No. 1 in west ', ' Xu Xiang ', ' Henan emperor's No.1 ', ' river Mi No. 3 ', ' Chu Hong ', ' east are red ', ' Feng Yue ', ' osmanthus sea 4 ', ' H-15 ', ' Hua You ', ' Jin Mei ', ' all over the sky red ', ' logical mountain 5 ', ' force plants No. 3 ', ' tall building is No. 1 sub- ', ' new to see No. 2 ', ' rivers and mountains is tender ' Kiwi berry distinguish.
Compared with prior art, advantages of the present invention:
1. morphological markers simple, intuitive, but quantity is few, polymorphism is poor, vulnerable to environmental influence.Molecular labeling operation Simplicity, it is detectable in each tissue and developmental stage of plant, not by season and environmental restrictions.Quantity is more, throughout entire Genome.Polymorphism is high, and there are many allelic variations between kind.
2. primer of the invention can expand in kiwi series kind and obtain different size of DNA fragmentation.The molecule mark Note amplification stability, can be used to carry out the identification of Kiwi berry ' Jin Mei ' kind.
3. molecular labeling primer specificity provided by the invention is high, applied widely, can be from the Mi of 40 multiple and different kinds ' Jin Mei ' kind is identified in monkey peach, is expanded using molecular labeling Geo13-84 primer pair DNA, only Jin Mei can be special The band for amplifying 161bp of property.
4. in addition to identifying ' Jin Mei ' kind according to specific band, can also according to stripe size and number to ' Bu Lunuo ', ' emerald ', ' your length ', ' magnificent light 2 ', ' Jin Kui ', ' peasants who dig gold ', ' Jin Xia ', ' Jin Yan ', ' gold and jade ', ' gold circle ', ' chief is close ', ' dragon Mountain is red ', ' MBR ', ' summer millet ', ' mill mountain 4 ', ' Qingyuan Qiu Cui ', ' No. WH-1 ', ' Hunan fiber crops No. 6 ', ' selecting No. 1 in west ', ' Xu It is fragrant ', ' Henan emperor's No.1 ', ' river Mi 3 ', ' Chu Hong ', ' east is red ', ' Feng Yue ', ' osmanthus sea 4 ', ' H-15 ', ' Hua You ', ' Jin Mei ', ' all over the sky red ', ' logical mountain 5 ', ' force plants No. 3 ', ' tall building is No. 1 sub- ', ' new to see No. 2 ', ' rivers and mountains is tender ' Kiwi berry distinguish.
