Genetic diversity of taraxacum germplasm revealed by sequence-related amplified polymorphism (SRAP) analysis

Abstract

Sequence-related amplified polymorphism (SRAP) and morphological markers were employed to determine the genetic diversity and relations among 11 population of taraxacum in northeast of China. Data on 34 morphological traits were collected and analyzed. A total of 795 polymorphic SRAP’s bands were scored with 20 combinations of primers. The genetic relationships analyzed with un-weighed pairgroup method with arithmetic mean (UPMGA) showed that 11 population of taraxacum were grouped into three clusters. The results reveal by SRAP molecular markers were consistent with those based on the agronomic traits, suggesting that SRAP markers could be used in the taxonomic analysis of taraxacum germplasm.

Key words: Taraxacum, sequence-related amplified polymorphism (SRAP), genetic diversity, un-weighed pairgroup method with arithmetic mean (UPMGA).
