Some notes on SNP markers data analysis and genome-wide selection methods in tree breeding (PDF).

Course notes for analysis of binary and count data. Solved examples for forest tree diseases.


Some Course notes and SAS examples for progeny test data analysis in tree breeding:

You need to have at least medium level SAS programming experience to run most codes.

* SAS tips for data manipulation

* Data examination using SAS (PDF).

* Half-sib progeny data analysis using SAS (PDF).

* Genetic Correlations and Correlated Response (PDF)

* Analysis of Diallels using SAS (PDF).
If you really need to analyze Diallel Mating Designs routinely, think about ASReml. It is much easier.


 

Hike in Goreme
With a group of students from the College of Natural Resources, we had Study Abroad Program in Turkey In June 2007. Hiking in Pigeon Valley (Goreme, Turkey).

We had a another trip in June-July 2009 to Turkey. Here is a picture from Black Sea Mountains. Click here to see more pictures

Current Research Projects

Marker Aided Selection in Trees (2007-2011, USDA): Discovery and genotyping of single-nucleotide polymorphisms have become affordable in recent years, but methods for applying these technologies to tree improvement programs are still lacking. As part of the Conifer Translational Genomics Network (lead by David Neal), my current research focuses on using markers in tree breeding, specifically in prediction of breeding values (using the mixed model theory and BLUP) in Pinus taeda breeding populations (with Ross Whettena and Steve McKeand).

Genetic Improvement of Pine for Fusiform Rust Disease Resistance (Forest Industry): A major threat to pine plantations in the southern USA. Research on fusiform rust disease includes new disease resistant gene discovery in elite pine clones, utilization of resistance genes in pine breeding programs (gene stacking, genotyping and association with disease occurance) and study of host pine genotypes by pathogen interactions (with Ross Whetten, Steve McKeand, Saul Garcia).

Regulation and Modeling of Lignin Biosynthesis (2009-2012, NSF): The mechanisms of regulation of lignin biosynthesis are largely unknown. The project seeks to build models to describe how the pathway is regulated and to reveal new control mechanisms, leading to lignin polymers. The project will use the model woody plant, Populus trichocarpa (black cottonwood) and a systems approach including advanced quantitative methods of genomics, proteomics, biochemistry and structural chemistry, to provide a comprehensive analysis of the regulation of lignin biosynthesis (with Vincent Chiang, Ron Sederoff, Joel Ducoste and John Ralph).
