APPLICATION OF SSR MARKER IN EVALUATING THE GROWTH OF HYBRID EUCALYPTUS LINES.

Abstract

Molecular marker assisted selection has been increasingly paid more attention because it can shorten the selection time, even selecting in the seedling stage. The molecular markers which link with the interested traits will be used to evaluate in order to select the superior lines. 13 SSR primer sets have been used to evaluate the growth of Eucalyptus hybrid lines from some of the hybrid combinations. The initial results have shown that the evaluation based on the molecular markers has been in conformity with the growth of progeny trials of the hybrid lines grown on diffirent sites. Among of the 13 SSR primer sets, six primer sets (including of EMBRA28, 80, 93, 111, 187, and 361 primers) have been identified to be able to use to distinguish between the fast growth and the slow growth lines. However, the present study has used only a little of primers and hybrid lines, so we need to make an experiment with alarger number of primers and lines.
