Although there are over sixty mustard (Brassica juncea (L.) Czern & Coss) germplasm accessions are present in the gene bank of PGRC [6] in Sri Lanka, genetic diversity and the relationship among these accessions have yet to be studied fully.
For eight cultivars, information about the mucilage was available from a preliminary screening conducted by PGRC in 1999.
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., 2002).
The objective of this analysis was to assess the geographic patterns of RAPD variation in the world collection of cultivated flax maintained at PGRC. Molecular markers are less affected by environmental factors than those morphological and botanical characters previously used to describe flax variation and should be more informative in determining geographic patterns of flax diversity (Harlan, 1986).
The PGRC collection of flax germplasm is largely a duplication of the flax collection maintained in the United States National Plant Germplasm System.
Approximately 10 to 15 seeds of each cultivar were randomly selected from the accession in the PGRC oat collection and grown in the greenhouse at the AAFC Saskatoon Research Centre.
Abbreviations: bp, base pair; AFLP, amplified fragment length polymorphism; PCR, polymerase chain reaction; PGRC, Plant Gene Resources of Canada; SSR, simple sequence repeat.
The RAPD characterization procedures used were the same as those previously applied for all the flax accessions held at PGRC and include seed planting in greenhouse, extraction of DNA from young leaves, PCR analysis of isolated DNAs using RAPD primers, and scoring of DNA fingerprints (Fu et al., 2002a).
This average proportion of fixed loci was lower than those observed for all of the other cultivars in the PGRC collection (51.2% including fiber flax cultivars), higher than those for the flax landrace accessions assessed (42.7%), and comparable with those for the whole flax collection (45.8%; Fu et al., 2002a; Fu et al., unpublished).
