[Analysis on SNPs linked with wood properties of Populus nigra L. gene resources].

In this study, 115 Populus nigra L. collected from Europe were used as materials. They were detected for SNPs of genes linked with lignin and holocellulose (4CL, PAL and CesA2) by TaqMan technology and correlations between SNPs and wood properties (the wood speciely gravity, fiber length, fiber width, microfibre angle, lignin, holocellulose content and a-Cellulose content) were also studied.

[SSR molecular markers related to wood density and fibre traits in poplar].

In this study, field experiment was carried out following the randomized complete block design with five replications in 1999. F2 population was derived from a cross between the female ZH3 and the male ZH1 (ZH3, ZH1 were selected from F1 individuals derived from the cross of Populus deltoides with P. cathayana, produced by HUANG Dong-Sen in 1973).
