Phenotypic and molecular marker analysis uncovers the genetic diversity of the grass Stenotaphrum secundatum.

ABSTRACT:

Background

Stenotaphrum secundatum is an important grass with a rich variety of accessions and great potential for development as an economically valuable crop. However, little is known about the genetic diversity of S. secundatum, limiting its application and development as a crop. Here, to provide a theoretical basis for further conservation, utilization, and classification of S. secundatum germplasm resources, we used phenotypic and molecular markers (single-nucleotide polymorphisms, SNPs; sequence-related amplified polymorphism, SRAP; inter-simple sequence repeat, ISSR) to analyze the genetic diversity of 49 S. secundatum accessions.

Results

Based on seven types of phenotypic data, the 49 S. secundatum accessions could be divided into three classes with great variation.
