Comment When mapped as a QTL Vrn-B1 showed closest association with Xgwm408-5B {10007}.
All common wheat genotypes carrying Vrn-B1a studied so far have a 6.8 kb deletion in intron 1 (Triple Dirk B, Bersee, Festiguay, Mara, Milturum, Noe, Spica) {10202}.
Two variants of Vrn-B1a were distinguished in {920,921}. Carriers of an earlier designated Vrn2b (characterized by Diamant 1*8/Skorospelka 35 5A) showed accelerated flowering after 15 and 30 days of vernalization, whereas carriers of Vrn-2a, (characterized by Ank-18 and Saratovskaya 29*8/Mironovskaya 808 5A) did not respond to these periods of vernalization. This distinction was not made in the above list.
