The common wheat (Triticum aestivum L.) cultivar 'Marquillo' was crossed and backcrossed to 'Marquis,' and was also crossed with the 'Chinese Spring' monosomics. Seedlings from the F2 families from the backcross and from F2 and F3 families from the crosses with the monosomics were tested with race 56 of stem rust (Puccinia graminis tritici Eriks. and Henn.). The results indicated that 'Marquillo' carries a single recessive gene for resistance to race 56, located on chromosome 3B. The gene which was identified as Sr12, appears to be temperature sensitive and was affected by a recessive modifier.Key words: wheat, Triticum aestivum, Puccinia graminis, monosomics, rust resistance.
