2.5% of at least 2000 individual plants. Our above-
mentioned studies proved that a variety with an
SSR-HLR > 95% is uniform. In other words, a variety
is uniform if the SSR-HLR is > 95% and the seed
purity is ≥ 97.5%. Considering the experimental cost
of testing seed purity using SSR markers, the sample
size is set at 100 individuals. Since the sample size is
far less than the recommended 2000 individuals, the
seed purity threshold is reduced to > 95% when
assessing wheat variety uniformity. Therefore, the
