Gene action for grain protein content in durum wheat

The aim of this study was to determine the gene action and combining ability of durum wheat for grain protein content. During the three year period a diallel cross was carried out with five modern parents of durum wheat – ‘Victoria’, ‘Deni’, ‘Superdur’, ‘Progres’ and ‘Predel’. Ten hybrid combination...
