Abstract: Trichoderma strain Y15 was isolated from the vegetable soil under Shandong greenhouse, and identified by analysis of internal transcribed spacer regions of the rRNA gene cluster (ITS), partial sequences of transcription extensions factor 1alpha (tef1α) and morphological characteristics. Results show that Y15 is T. paratroviride. The strain is colony dense, panniform, greyishgreen on PDA. Conidiophore main axes is long with short secondary branches, not extensively rebranching. Its branches are coupled or verticillate. Phialides usually has 2~4 verticils, lageniform or subulate, straight or flexuous. Conidia is subglobose to obovoid, greenish and smooth. The tef1α sequence of strain Y15 has 99% homology with strains S489 and S385 of T. paratroviride type, and has the closest genetic relationship with them in phylogenetic tree. It is originally reported in China as a new Chinese record of genus Trichoderma.

Key words: Trichoderma paratroviride, ITS, tef1-α, Chinese new record
