Twenty-five durum wheat (Triticum durum L.) lines, one triticale (X Triticosecale Wittmack) cultivar and four wheat (T aestivum L.) cultivars were evaluated in six trials under sprinkler irrigation taking into account the grain yield, agronomic characteristics and disease resistance. The durum wheat lines 14 (61150/Leeds//Gallo "S"/3/Garza "S"/4/Mexicali "S"/5/S-15-Crane "S"), 21 (Boyeros "S"/Cocorit-71/5/Crane "S"/Ganso "S"//Marte "S"/3/Tildillo "S"/4/Memo "S"), 25 (Gallareta "S") and 8 (Gediz "S"/Yavaros "S"), showed the following traites: resistant to stem and leaf rusts; moderately resistant to powdery mildew; susceptible to leaf spot, and short to medium stature. These lines presented good grain yield in soils with low acidity. However, they did not differ in yield from the wheat cultivar IAC-60, the most cultivated actually in the State of São Paulo and from the triticale Álamos. The durum wheat line 19 (Mindum/Kingfisher "S"//Sandpiper) showed at the same time immunity to the causal agents of stem (with exception of line 21) and leaf rusts and moderate resistance to the causal agent of powdery mildew. The cultivars Álamos (triticale) and IAC-29 (wheat) exhibited immunity to the causal agents of powdery mildew. All considered genotypes were susceptible to the leaf spots patogens, with exception of the durum wheat line 6 (Dackiye/Gerardo Vezio 394) which was moderately resistant.
