The flax seed used for screening of the world collection originated from 1689 flax accessions regenerated during one of the years 1999-2001 by PGRC at Saskatoon (Diederichsen et al.
Thirty accessions from the PGRC world collection produced, in addition to the soluble mucilage, an insoluble gelatinous precipitate which could not be removed by centrifugation or filtration and, therefore, influenced the viscosity measurements.
The 15 accessions of the world collection with the highest and lowest MIV are listed in Tables 5 and 6, respectively; the screening results for all accessions can be found in the PGRC Internet accessible database http://www.
A screening of the PGRC world collection identified genetic resources with lower and higher values (range: 22.

About 10 to 15 seeds of each accession were sampled from the PGRC flax collection and grown in a greenhouse at the Saskatoon Research Centre, Agriculture and Agri-Food Canada.
These regional patterns of RAPD variation are significant for the management and utilization of flax germplasm, particularly for those in the PGRC collection.
Establishing a core subset of flax accessions from the PGRC collection can enhance the management and utilization of flax germplasm (Brown and Spillane, 1999), but challenges remain in the applications of sampling to capture the existing variability.
The PGRC flax collection displayed a large amount of genetic diversity in flax germplasm.

This average proportion of fixed loci was lower than those observed for all of the other cultivars in the PGRC collection (51.
