  1. Frequency of α-gliadin gene copies derived from the Gli-A2 locus in genomic DNA of three 'Chinese Spring' accessions and in the homozygous deletion line 6AS-1 of 'Chinese Spring' missing the short arm of chromosome 6A, as determined by pyrosequencing on two SNP positions (T2/C3 & GG20/A21), n = number of technical repetitions performed per 'Chinese Spring' line.; a, b: a different letter indicates a statistically significant difference between the two samples; LSD for the Gli-A2 frequency among 'Chinese Spring' lines = 3.3% ± 0.004 at P < 0.001 (general ANOVA; Genstat).
