[0002] SCARMA MARKER FOR DISSEMINATION OF BLUEBERRY AND USE THEREOF {

The present invention relates to SCAR (Sequence Chracterized Amplified Region) markers for discriminating blueberries and their use, and more particularly, to a SCAR primer set for discriminating blueberry varieties, a method for discriminating blueberry varieties using the SCAR primer set, And a kit for discriminating a breed.

Blueberry (Vaccinium spp.) Is a shrubby crop belonging to the genus Vaccinium (Cyanoccous) section of the family Ericaceae. It is one of the world's top 10 super foods of the Time magazine. It is anthocyanin, It is also known as the 21st-century fruit tree because its efficacy has been acknowledged by its effective ingredients. Blueberries are also known to have effects such as vision recovery and enhancement, retinal degeneration and cataract prevention, carcinogenesis inhibition, and antioxidant effects.

Blueberries, known as the origin of Europe, such as North America and Finland, have been widely known for their taste and efficacy. Since the 1950s, cultivars have been developed and about 200 varieties of blueberries are known. Currently, about 100 varieties of blueberries are cultivated in Korea, but it is difficult to distinguish the correct varieties and the characteristics of purchased varieties are different.

Molecular markers, which are one of the methods to identify fruit varieties such as blueberries, can be useful because they can quickly distinguish cultivars without being affected by the cultivation environment or growing season of the crop. Molecular markers are a method of expressing individual polymorphisms in the nucleotide sequence differences of DNA, which is the essence of genetic phenomena, and include microsatellite or nucleotide sequence-based markers consisting mainly of repeating simple nucleotide sequences, or RFLP (Restriction Fragment Length Polymorphism) probe or SCAR (Sequence Characterized Amplified Region) marker.

In particular, the Random Amplified Polymorphic DNA (RAPD) method is most commonly used because it is easy and simple to analyze among various analysis methods. However, the RAPD method has disadvantages in that it is difficult to expect reproducible experimental results because the results may vary depending on the reaction conditions. In order to solve this problem, a method of performing PCR by preparing a new SCAR (Sequence Characterized Amplified Region) primer through cloning and sequencing of specific DNA bands generated from RAPD analysis results can be used. SCAR primers prepared in this manner can be used as more precise and finer primers. Korean Patent Registration No. 10-1457944, for example, discloses a scam marker for discriminating persimmon varieties and uses thereof. The need for the development of marker markers for the identification of blueberry varieties to prevent the incorporation of varieties of distribution seedlings using such molecular marker technology is required in order to develop molecular marking technology for blueberry varieties identification .

The purpose of this study is to develop molecular markers for the identification of blueberry varieties which can be used as a breeding certification technology in domestic blueberry distribution for the purpose of preventing the inclusion of variety in the distribution seedlings.

However, the problems to be solved by the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.

The first aspect of the present invention provides a SCAR primer set for discriminating blueberry cultivars comprising a set of primers selected from the group consisting of SEQ ID NOS: 1-32.

According to a second aspect of the present invention, there is provided a method for producing a plant, comprising the steps of: a) extracting genomic DNA from a blueberry to be cultivated; b) amplifying the DNA using the extracted genomic DNA as a template using the SCAR primer set according to the first aspect of the present invention; And c) analyzing the amplified DNA product.

The third aspect of the present invention can provide a kit for discriminating blueberry cultivars comprising a SCAR primer set, a DNA polymerase, dNTPs and a buffer solution for PCR reaction according to the first aspect of the present invention.

Using the SCAR marker for discriminating blueberry varieties according to the present invention, it is possible to accurately identify the varieties of more than 45 kinds of blueberries, so that it can be utilized as a breed identification technology for prevention of the inclusion of varieties of distribution seedlings and distribution of domestic seedlings. In addition, SCAR markers are not affected by environmental conditions such as reaction conditions as compared with other PCR markers, and thus can be used as more accurate and detailed molecular markers.
