Embodiment Construction

[0019] Part of the basic information data of pears, stable morphological feature data, cytology data, S gene data, and molecular fingerprint data are used to establish the identification number of pear varieties.

[0020] For basic information data, select two descriptors with common characteristics as the information of pear variety ID, namely "scientific name" and "origin"; for morphological characteristics data, select stable descriptors, namely leaf edge serration, fruit shape, Four descriptors of fruit surface color and sepal state; cytology data adopts chromosome ploidy data; S gene data; molecular marker data adopts SSR fingerprint data. One site with good polymorphism in the Pyrus plant was selected, namely NH007b. In the more than 500 pear varieties identified by this marker, 24 alleles have been expanded respectively.

[0021] Method for establishing pear variety information ID card data:

[0022] 1. Use an Arabic numeral to indicate the scientific name of the pear;

[0023...

Abstract

The invention relates to a method for establishing identity card (ID) number of pear variety. In the method, one digit number represents the scientific name of the pear; two English-letter country domain represents the producing country of the pear; two-digit number represents the producing province of the pear; one digit number represents the leaf margin sawtooth shape of the pear; two-digit number represents the fruit shape of the pear; one digit number represents the fruit color of the pear; one digit number represents the sepal state of the pear; one digit number represents the germplasm ploidy of the pear; a gene code represents the S gene data; two digit number represents molecular marker data; and the digit and the letter coded data string determines the ID number of the pear. By the method, the ID number of the pear variety is coded according to the variety, the original producing area, properties and gene data. The method has the characteristics of clear and bright markers and convenience of identification and is applicable to determining ID number of the pear and other fruits.

Description

Technical field [0001] The invention relates to a fruit tree variety identification technology, in particular to a method for establishing a pear variety ID card number. Background technique [0002] my country is the center of pear origin, with abundant pear variety resources, with more than 2,000 pear germplasm resources originating in my country. For more than 60 years since the founding of the People’s Republic of China, after several generations of hard work, my country has basically mastered the germplasm resources of pears and established the "National Fruit Tree Germplasm Xingcheng Pear and Apple Nursery" to secure the diversified germplasm resources. save. As of the end of 2010, 14 pear species and more than 1,000 pear germplasm resources have been safely preserved, making it the world's largest collection of Oriental pears and a diversity research and development center for pears. [0003] How to identify pear varieties has always been a big problem for researchers, prod...
