Lead Institute FG Institute of Forest Genetics

Studies on stability, growth and diversity of progenies of crosses from selected tree species under various climatic and edaphic conditions

Methods of cross breeding are useful for the improvement of growth, stability, and adaptability especially regarding climate change. For Scots pine (Pinus sylvestris L.) and hybrid larch (hybrid between European and Japanese larch) a number of progeny tests exist. Results of these tests will show growth performance of the respective progenies and hybrids.

Background and Objective

The objective of this project is to investigate the possibilities of crossbreeding for improvement of growth, stability, and adaptability especially regarding climate change and its consequences for genetic constitution and diversity. Furthermore parameters of quantitative genetics like heritability shall be estimated and gene markers detected.

Approach

Object of the investigation are progeny tests of Scots pine and trials with hybrids between European and Japanese larch.

Results

Results of older progeny tests showed the possibility to improvement growth and quality and to combine both traits together positively by means of cross breeding. Genetic constitution and combining ability of selected parent trees may vary considerably.

For larch the outstanding growth performance of hybrid larch was confirmed due to the results of the progeny tests. Superiority of hybrid progenies was between 20 and 30 % vor single tree volume.
