Abstract
Durum wheat (Triticum turgidum) cultivars (Mindum, Spelmar, Arnautka, Kubanka, Acme, Golden Ball, and Entrelargo de Montijo) used as standard or supplemental differentials for wheat stem rust were studied for resistance to selected pathogen cultures in the seedling stage. The presence of Sr9d in Mindum, Spelmar, and Arnautka was verified by using an avirulent race, Pgt-MCC, to inoculate F 1 , F 2 , and F 3 plants from crosses of these cultivars with the susceptible cultivar Glossy Hugenot. Mindum and Spelmar had an additional incompletely recessive gene for resistance to the race Pgt-QTH, and Arnautka a dominant gene for resistance to Pgt-GMC (...)
