Establishment of Simple Sequence Repeat Fingerprint for Identification of Mungbean Varieties (Vigna radiate L.) Grown in Liaoning
摘要
Abstract
Objective:This study aimed to establish a DNA fingerprint for rapid and accurate identification of mung bean varieties grown in Liaoning.Methods:A total of 48 mung bean samples from different varieties were used to construct a fingerprint database and a DNA fingerprint with 15 pairs of polymorphic simple sequence repeat (SSR) primers.Results:A total of 58 alleles were detected,2-7 of which,with an average of 3.9,were detected with each pair of the primers used,and 13 specific bands were obtained,accounting for about 22.4% of the total.The polymorphic information content (PIC) varied from 0.114 5-0.776 4,with an average of 0.378 4.Five pairs of efficient primers were selected.The discrimination rate obtained with their combination was as high as 75%,while a discrimination rate of 89.68% was obtained with a combination of all 15 primer pairs.Based on these results,the DNA fingerprint database composed of the digits 0 and 1 and the SSR fingerprint were established,which allowed unequivocal identification of all the varieties except a few unique ones.Conclusion:The SSR fingerprint presented in this study can open up a new way of identifying mung bean varieties and provide a basis for mung resource evaluation and protection as well as breeding of new varieties.关键词
