Table 1 PCR markers for determining the presence of different alleles ofVRN-A1,VRN-G1in tetraploid Timopheevi wheats and diploidAe. speltoides

From:The occurrence of spring forms in tetraploid Timopheevi wheat is associated with variation in the first intron of theVRN-A1gene

PCR marker Name Primer (5’ → 3’) Target allele(s) Expected pro-duct size (bp) Annealing temp. (°C) Reference.
