Abstract:

DNA fingerprint is a useful tool for identification new cultivars, cultivars’ authenticity and seed purity in wheat production and trade. In the present study, 15 SSR markers and 20 AFLP-SCAR markers were employed as DNA fingerprints of 455 wheat cultivars collected from 12 provinces and eco-regions of China. The fingerprints built by the two kinds of marker could explore the cultivars’ genetic diversity more reliably. Therefore, an approach to build wheat fingerprints was set up by connecting both SSR and AFLP-SCAR codes. In this paper, we exampled the way of constituting DNA fingerprints for wheat cultivars by 10 pairs of SSR marker and 10 pairs of AFLP-SCAR marker. The approach is put forward to converting DNA fingerprint code to bar code and give every wheat cultivar an ID number in the future.

Key words: Wheat, DNA fingerprint, SSR marker, AFLP-SCAR marker
