Abstract
Seedlings of 47 varieties or strains of 16 species of'Triticum, 44 varieties or strains of 19 species of Aegilops, 23 varieties or strains of 6 species of Hordeum, one strain of Hc, ynaldia villQsa, one strain of Avena sativa and 4 selections of Aegilotricum were tested with Puccinia graminis f. sp. Tritici 11. The experimental results are summarized as follows : 1. Among species of Einkorn group of Triticum, three strains, of Triticum monococcum and one strain of T. aegilopoides var. boeticum were susceptible to Puccinia grc, ninis f. sp. Tritici 11, but one strain of Triiicum monococcum (early) was resistant to it. Eight species of Emmer group : Triticum dicoccoides, T. dicoccwa, T. durum, T. turgidum. T. polonicwa, T. persicum, T. pycmidale and T. orienta:le were su:sceptible. Three strains of T'riticum Timopheevi belonging to Timopheevi group weire highly resistant, but one strain of this species was moderately resistant. Five species of Dinkel group : Triticum Spelta, T. vulgare, T. conlrpactum, T. sphaerococcum and T.
