Resistance to foliar diseases was studied in 67 samples of 8 Triticum L. species and 1 amphidiploid from the collection of the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR). Under the laboratory conditions resistance to leaf rust, Septoria nodorum blotch (SNB) and Helminthosporium leaf blotch (HLB) was studied at two temperatures. Resistance to hemibiotrophic pathogens was studied at concentrations of spores: 10⁵, 10⁶ and 5 × 10⁶ conidia ml⁻¹—for SNB and 2 × 10⁴ and 4 × 10⁴ spores ml⁻¹—for HLB. Spores’ concentrations on the field experiments were 3 × 10⁴, 10⁶, 2 × 10⁴ for leaf rust, SNB and HLB, respectively. Most of the samples were susceptible to the diseases at the seedling stage in all experiments. Adult plant resistance was studied after plants spraying with suspensions of pathogens’ spores and inoculation with microchambers. Under the laboratory conditions, only samples of T. monococcum L. and T. sinskajae A. Filat. et Kurk. were resistant to leaf rust at two temperatures. Under field conditions, samples of T. monococcum and T. sinskajae, two samples of T. dicoccum (Schrank) Schuebl. and one each of T. polonicum L. and T. turanicum Jakubz. were highly resistant to leaf rust. Two samples of T. persicum Vav. and T. sinskajae were resistant to HLB at 7th day after inoculation under high inoculation pressure at 22 °C, and all were susceptible at 28 °C. All samples were susceptible to SNB. Under field conditions, all samples were highly susceptible to SNB and HLB.

在NI Vavilov全俄罗斯植物遗传资源研究所（VIR）的馆藏中，对67种8种小麦和1种二倍体的叶面病抗性进行了研究。在实验室条件下，对叶锈病的抵抗力分别在两个温度下进行了诺氏斑霉病（SNB）和蠕虫孢子病（HLB）的研究。耐hemibiotrophic病原体在孢子浓度进行了研究：10 ⁵，10 ⁶和5×10 ⁶个分生孢子毫升^-1 -用于SNB和2×10 ⁴和4×10 ⁴个孢子毫升^-1 -用于HLB。孢子在田间试验浓度分别为3×10 ⁴，10 ⁶，2×10 ⁴对叶锈病，SNB和HLB ，分别。在所有实验中，大多数样品在幼苗期都易感染该病。在植物喷洒病原体孢子的悬浮液并接种微腔后，对成年植物的抗性进行了研究。在实验室条件下，仅T. monococcum L.和T. sinskajae A. Filat的样品。et Kurk。在两个温度下均能抵抗叶锈病。在田间条件下，可得到T. monococcum和T. sinskajae的样品，这是T. dicoccum（Schrank）Schuebl的两个样品。和每一个T.  polonicum L.和T. turanicum雅各布兹。对叶锈病具有很高的抵抗力。百日草的两个样品。在22°C的高接种压力下接种后第7天，T。sinskajae和T. sinskajae对HLB有抗性，并且在28°C时均易感。所有样品均易受SNB影响。在野外条件下，所有样品都对SNB和HLB高度敏感。
