Provides practical procedures to follow when planning, designing and analysing tree improvement trials.

Experimental Design and Analysis for Tree Improvement provides a set of practical procedures to follow when planning, designing and analysing tree improvement trials. + Full description

Using many fully-worked examples, it outlines how to: design field, glasshouse and laboratory trials; efficiently collect data and construct electronic data files; pre-process data, screening for data quality and outliers; analyse data from single and across-site trials using either GenStat or SAS; and interpret the results from statistical analyses.

The authors address the many practical issues often faced in forest tree improvement trials and describe techniques that will give conclusive results with the minimum expense. The techniques provided are applicable to the improvement of not only trees, but to crops in general.

Building on the success of the first edition, this new edition has been fully revised and updated to relate to the latest commercially-available software packages for design generation (CycDesigN) and data pre-processing and automated generation of programs for statistical analysis (DataPlus). For analysis, it now provides both GenStat and SAS programs as generated by DataPlus.

Dr Emlyn Williams, a statistician with over 30 years research experience, is at the forefront of statistical research into the construction of efficient experimental designs, particularly for use in field, glasshouse and laboratory trials.

Dr Colin Matheson and Dr Chris Harwood and are internationally recognized tree breeders with extensive experience in developing, implementing and managing breeding programs for a wide range of Australian native and introduced tree species.

The authors, all from CSIRO Forestry and Forest Products, have over 20 years experience in several countries in the various activities involved in design and analysis of field trials. For many years they have been involved in training courses based around the book’s contents, held both in Australian and overseas
