Abstract:

To explore the genetic relationship of Shushanggan apricot, SSR molecular marker technology was used by PCR amplification and a modified polyacrylamide gel electrophoresis, 18 pairs of SSR polymorphism primers were identified in nine varieties (types) of Shushanggan apricot and other apricots, to get the DNA fingerprint. The genetic relationship between Shushanggan apricot and other apricot varieties (types) were identified from different DNA levels. The genetic relationship of apricot varieties (types) were analyzed by clustering. The results showed that Shushanggan apricot had two different varieties, namely Shushanggan apricot No.1 and Shushanggan apricot No.2. Shushanggan apricot No.4 and Shushanggan apricot No.1 were the same type. The close genetic relationship to Shushanggan apricot No.1 was Gongliu wild apricot> pearl oil apricot> Disishi 61 Tuan ancient apricot, the genetic similarity coefficient ranged from 0.673 to 0.808. Shushanggan apricot No.3 and Shushanggan apricot No.2 were the same type, and they were closely related to Liguang apricot, the genetic similarity coefficient ranged from 0.654 to 0.846. Huocheng wild apricot was far related to Shushanggan apricot.
