Analysis of variance on combined diosgenin levels from the three sites and two years revealed that accession, accession x year, and site x year effects were significant for diOSgenin content, whereas site, year,and site x accession effects were not.

Red oat was genetically more diverse than its common and hull-less counterparts, and hull more related to common oat than red oat, and landrace and non-landrace accessions displayed similar AFLP variation patterns.
Allelic Diversity Changes in 96 Canadian Oat Cultivars Released from 1886 to 2001
- Yong-Bi Fu, G. Peterson, G. Scoles, B. Rossnagel, D. Schoen, K. Richards
- Biology
- 1 November 2003
Findings indicate that allelic diversity at particular loci, rather than average genetic diversity, is sensitive to oat breeding practices and indicate the need for attention to be paid to Oat germplasm conservation.

The risks to pollinator biodiversity in Canada are examined through a generalised model with inputs on environmental sensitivity, pressure indices, and societal response as they relate to the…
Impact of plant breeding on genetic diversity of the Canadian hard red spring wheat germplasm as revealed by EST-derived SSR markers
- Yong-Bi Fu, G. Peterson, Ju-Kyung Yu, Li-feng Gao, J. Jia, K. Richards
- Biology, MedicineTheoretical and Applied Genetics
- 8 February 2006
Findings from genomic SSR markers suggest the Canadian wheat breeding programs have reduced genetic diversity in the hard red spring wheat, and illustrate the impact of theCanadian wheat breeding on the transcriptional segments of the wheat genome.
