Abstract:

In order to carry out pear variety resource identification work more scientifically, quickly and accurately, the article reviewed the SSR fingerprinting ID technology, the research progress and application of this technology in pear variety identification, and analyzed in detail the current problems of this technology in terms of simplicity, expandability, and collection and analysis of tagged data, etc. To address the above problems, the article introduced the direction of improvement such as using more efficient coding methods, data expansion, and fluorescent labelling capillary electrophoresis detection technology, etc. The article also looked forward to the future of SSR fingerprint ID technology combined with the new generation of sequencing technology, to achieve faster, more accurate and more efficient identification of pear varieties.

Key words: pear, SSR marking, fingerprint spectrum, molecular ID card, research progress
