Notes:
Manganese (Mn) deficiency is a major constraint of alkaline soils around the world, particularly for cultivation of durum wheat, which is more intolerant of low Mn levels than either common wheat or barley. Genetic variation for Mn efficiency exists in the current germplasm of durum wheat. Several restriction fragment length polymorphisms (RFLPs) previously shown to be linked to the Mel1 locus for Mn efficiency on chromosome 4HS of barley were tested on 88 selected F2 plants of the durum cross, ‘Stojocri 2’ (Mn efficient) בHazar’ (Mn inefficient). The Mel1-linked RFLP marker Xcdo583a was closely linked to the trait and explained over 42% of the total variation for Mn efficiency in the ‘Stojocri 2’/‘Hazar’ F2 progeny. This marker has the potential to provide a valuable tool for the marker-assisted selection of Mn-efficient durum progeny derived from crosses with ‘Stojocri 2’.
