Application of allochroic method on screening excellent hybridized strains of Hypsizygus marmoreus

Abstract:

[Objective] To shorten the process of screening excellent hybridized strains in Hypsizygus marmoreus. [Methods] We used the allochroic method in this study. [Results] The results showed that the color change of the allochroic medium was concordant with decolorization ratio (D value), of which the medium was yellow and the D value was positive value, and the medium was blue and the D value was negative value. Furthermore, we found that the D value was related to the main agronomic characters closely, and the mycelial growth of the strains with positive D value was faster than the strains with negative D value, the output per bottle and the number of normal fruit bodies had positive relationship with D value, and the number of abnormal fruit bodies had negative relationship with D value. [Conclusion] Application the allochroic method could screen the excellent hybridized strains quickly and easily, and could shorten the breeding process of H. marmoreus.
