Minimal Marker Set

Accurate identification of named accessions in germplasm collections is extremely important. Thus, an inexpensive, reliable, and rapid genotyping method is essential because it avoids the need for laborious and time-consuming morphological comparisons. Single Nucleotide Polymorphism (SNP) marker panels containing large numbers of SNPs have been developed for many crop species, but such panels are much too large for basic cultivar identification. Here, we have identified a minimum set of SNP markers (32; see table below) sufficient to distinguish wheat varieties genotyped at Bristol University (over 2,500 varieties).

Examples of SNP profiles:

• A01_1_Peragis,0,1,0,0,0,2,1,0,0,2,0,2,0,0,1,0,0,0,1,0,0,0,0,2,0,0,0,0,1,1,0,0
• A01_597_kyalami,1,0,2,0,0,2,0,0,0,0,2,2,1,2,0,0,0,1,0,2,2,0,2,9,0,2,2,0,0,0,0,0

We have developed minimal marker sets for other speices:

• Apple
• SARS_CoV_2
