The purpose of the options listed here is to facilitate learning the Tree Breeding Tools offered on this web-site. These tutorial tools should facilitate the understanding of the programs and concepts (e.g. group coancestry, group merit selection, status number). More tutorial entries can be found elsewhere on this web.

Minicourses on quantitative genetics focusing on "my" favourite pets, there are three somewhat different variants of the material: a web page; a document; a slide presentation.

There are a number of Examples, where you can try to solve or study solutions and improve your understanding

There is a glossary in construction, which is especially designed to be helpful to TBT users;

 A review about status number Lindgren D & Kang KS. 1997. Status number - a useful tool for tree breeding Research Report of the Forest Genetic Research Institute of Korea 33:154-165. This is the last article in the last volume of the series, and thus in a way the last word in the history of Forest Genetic Research Institute of Korea before it was merged with the other sectors of forest research into Koran Forest Research Institute. 

A powerpoint presentation about TBT presented at a conference in Finland March 24, 2001. A description of TBT presented at the proceedings for the meeting in Finland (Lindgren, D 2002. Tree Breeding Tools (TBT). Proceeding at Nordic Group for Management of Genetic Resources of Trees Meeting in Finland 2001. In Haapanen M & Mikola J (Eds): Integrating Tree Breeding and Forestry - Proceedings from a meeting of the Nordic Group for Management of Genetic Resources of Trees. The Finnish Forest Research Institute Research Papers 842, p 59-70)

 COANCESTRY_MATRIX.XLS is to show how a coancestry matrix looks like in a worksheet.

 The introduction to TBT contains information, which is recommended before making extensive use of the site or if you encounter problems

A rather complete source of information about genetic relatedness, were given in lecture notes by Elizabeth Thompson.which can be found at this link http://zwets.com/pedkin/thompson.pdf

I appreciate feed back, preferable by E-mail. Inform me if you run into problems. People may interpret the programs or even the examples in all sort of unexpected ways and then run into trouble, and if I get to know how, I may take actions so it will not happen again. The programs may not work for all situations. And I may have done direct mistakes (it would not be the first time), but how can I know if no-one tells me... Thus, send a comment to: dag.lindgren@genfys.slu.se

Many thanks to people who have tested the programs, concepts and examples by trying to solve the examples, in particular Nebi Belir, Matti Haapanen, Anni Harju, Kyu-Suk Kang, Huan-Lin Lai,  Darius Danusevicius, Milan Lstiburek...
