TÓM TẮT
Cordyceps (Cordyceps militaris) is a valuable agricultural medicinal crop in many countries. In recent years, this mushroom has become increasingly popular in Vietnam. This study presents the results of a diversity assessment of eight commercial Cordyceps strains collected from different provinces in Vietnam. Morphological characteristics such as color, length, width, and surface features of the mushroom fruiting bodies were studied. Molecular markers of two genes of the MAT1-1 locus (MAT1‑1‑1, MAT1‑1‑2) and one gene of the MAT1-2 locus (MAT1-2-1) were used for genetic evaluation. The results of the analysis showed that all the strains were diverse in their morphological characteristics. Seven strains P1, P3, P4, P5, P6, P7, P8 had only one MAT1‑1 mating type locus. Only one strain P2 contained two MAT1-1 and MAT1-2 loci simultaneously. This result shows the diversity of Cordyceps strains in Vietnam and supports their selection to create new strains through sexual hybridization
