Abstract

Abstract: In order to breed new varieties of Lentinus edodes which can bear high temperature by UV mutation, a wild high temperature resistant L. edodes sample XG-1 was used as the starting strain. New varieties of high temperature resistant L. edodes were screened by different UV irradiation time and intensity, and the cultivated strains with better comprehensive characters were cultivated. Mutant XG-5, known as Jinxi 1 was screened when the mutation time was 25~30 s and mutation intensity was 12~16 W; Its fruited temperature was up to 38 ℃, so it belonged to high temperature resistant varieties. In leaning cultivation mode, the field of Jinxi 1 could reach 1.013 kg per bag (polyethylene bag size 17 cm × 33 cm), and the biotransformation rate reached 92.09%.

Key words: high temperature Lentinula edodes, UV mutagenesis, mutagenesis time, induced temperature, bioconversion rate
